holley sniper starts and dies
I have a 428 fe with a MSD Blaster 2 Ignition Coil, MSD Ignition Pro-Billet Ready-to-Run Distributor Ford FE, but that's all. Runs, then dies. Capability Range: Moderate Make sure the fuel pump is properly mounted and picking up fuel. Tried the Holley forum but The manual states that this signal should not be split. I'm glad this approach worked for you. Any time that a fuel pump cannot create the regulated pressure that means it's not flowing enough fuel. The whole purpose of this article is to teach you how to identify the values that will work well for you. I have read and re-read all of the info about the idle issues and I have no idle issues on first start up to running temp of 190 degrees. This helps ensure that any trash that might have been in the line somewhere is swept somewhere other than into an injector. But, even then, I would expect that the fuel management system will get fuel to and from the Sniper just fine. seems to be running rich at a idle. (Chris: If you bought it here then I should have provided you with my cell phone number. Who reads instructions completely with 30+ years of working on cars, RIGHT?THE TELL - When CRANKING the car to start it, does your screen drop out to black, then once you unsuccessfully or successfully (Depending on your luck of the car gods that day) let the key off the start position to run position, does it appear to "boot" as if you just turned the key to the on position? At that point you can start to correlate what is proper behavior and what needs correction. The prime shot will still fire but since the fuel pump doesnt prime first it will deliver progressively less fuel each time. sniper Installation If you're installing a Sniper EFI system and almost ready to crank it over for the first time, this is the video for you! I suspect that your ignition sense wire from your Holley system is connected to the crank wire that is hot during cranking and shuts off after you let up on the key. It is going on a 1966 coronet with 1964 413 wedge. How did you install the return line to the tank? Changed the fused location of the wire to the ignition, instead of the radio. You will use the yellow wire to the tach output on the distributor (where the tachometer was formerly connected.) Enjoy! Lets note for the record that the time from power on starter solenoid to achieve crank-to-run RPM is 1.13 seconds. Several things to cover here. I've gone through all the steps and cannot seem to solve the problem. You're not running your EFI system without a gauge are you? Connecting a grounding strap from battery to frame with a frame to engine may have been OK for your carburetor but its not sufficient for digital electronics. Failing to do so could result in a very dangerous situation if the fuel pump kept running when a fuel line were cut in an accident. And it may have improvedor it may have gotten worse. But as you go farther back, it only gets better. Any tips or info on cold starts? Is that an expectable by-product of adding this relay? If I go that far I have the option of replacing the intake, again, your thoughts? 4.56 rear gear and total weight is 2825 with me. features . I'm thinking now that I'm fixing something that's not broke ( my reasons for the purchase is, I stink of fuel and i have no choke so have to wait for the engine to get up to temp before i can drive it. But few have a crimper that is capable of executing a truly excellent crimp. When you remove a spark plug is it bone dry or dripping wet? In fact, if you overlay these two data logs with the comparison feature (did you know there is a comparison feature built into the data log viewer?) It will add fuel based on the temperature and won't affect your warm start.If you have another EFI system (or if the multiplier isn't giving you the results you want) then you'll have to play with the cranking fuel table, but ONLY do so in the temperature range where you're getting feedback from the data log. For the Sniper it is best to run resistor plugs. Seems like thats what its doing. Hard to answer. Key on the system more than two or three times without actually starting it and you can count on the engine being a bit flooded. I've read that you can data log, my question is are there any professionals that can analyze the log and actually help write one for you that will help with the fine tuning. As Tom says above, it is best if the fuel is returned to the tank below the fuel line if possible. Price Point: $$, EFI Systems based on You accidentally wired the switched 12V to the accessory side of the ignition switch. . This is most easily done using the blue fuel pump wire. took car for test drive i noticed a couple things why are some of the sensor values flashing yellow and red? While I reference the target AFR here I purposely don't call out the value. Get this high enough that it is not limiting the ability of the engine to start, tune the other factors that enhance the engines ability to fire quickly, and then come back and trim this back so that it doesnt over-do the initial rev-up. Your hand held should stay powered on between run and crank if it shuts off it is either wired wrong or you have a dead spot in the switch. Everyone else was backordered several months. I Had a holley sniper on this car with no issues whatsover. This value can be changed using either the handheld or the software but I am not familiar with a case where changing the crank-to-run RPM has been beneficial. Also check your cranking voltage if it starts hard. Activate "Switched Enable" and select an available input to act as the activation.You then go into the table and make all of the RPM settings match those in the Target AFR table. Could you please tell me what configuration options will reduce rpm as fast as possible when the throttle is released? #2 I have a return 1/4 pipe coming out of the fuel pump at the fuel tank. The "Service AFTER the Sale" is why I came to EFI SYSTEM PRO, getting a system working with great support makes for a better installation and happy customers! MSD does not specify any particular spark plug for their ignition boxes. superchargeddrt Well-Known Member Joined Aug 24, 2009 Messages 2,420 Reaction score 1,102 What this tells us: First, we dont have any huge problems. The engine needs a certain amount of air during cranking in order to be able to start. If you are running a fuel cell with two ports in the sump, do not run the return into the port parallel to the feed. First, don't get too worked up about the flashing yellow and red values. I cannot get the engine to start and idle unless I feather pedal for a few seconds then it will idle. Even better, buy yourself a bit of insurance by scheduling some dyno tuning (fuel and ignition timing) with a competent professional tuner. Full product line and accessories at excellent pricing. First, there is the obvious--the system has to learn. The way you write makes it so easy to understand. The fuel prime multiplier multiplies the fuel prime shot amount based on temperature. Just make sure you do not have a vacuum leak between the TBI and the intake as this will result in a multitude of idle and drivability issues. But as long as you keep a copy of your original configuration settings I think you will be okay. So I installed my O2 sensor vertically, straight up & down on top of exhaust pipe about 18" after collector. Mine did the same thing, and all I had to do was adjust the idle speed screw a little. EMI is what wipes out all the electronics. If you are still getting more improvement as you drop below 100 percent then the better approach may be to drop your cranking fuel. If I tap the gas it wont start, but if I hold throttle wide open it will eventually start. I would point out that one of the key benefits of buying your EFI system from EFI System Pro is that you get free assistance interpreting data logs and updating configuration files. My car idles beautifully @ about 800rpm. A throttle linkage extender and a progressive linkage kit. But I have MSD 6 AL. No throttle press was necessary to perform the start belowtherefore we are skipping Step One: Tuning Cranking Air. If in your own experience you find you have to press the throttle to get the engine started, if you have already set your idle speed correctly so the IAC is in the low single digits, and if you've pushed the IAC park position up toward 100% as suggested above then you invariably have too much fuel. Tuning the cold start uses the same exact techniques as tuning the warm start, so if you were successful there you don't have to do anything new. So try cutting both of those numbers in half and see what happens. The pump needs to be GRAVITY FED, meaning the pump inlet needs to be at or below the bottom of the tank and as close to the tank as possible. If not then stop and buy one now. Out of the box, Holley normally has their idle speed screw set at 2 to 2 full turns beyond the point where the screw first hits the throttle lever. At least not right away (after time-delay set in relay). Now were getting there. I really would like to replace the intake gaskets. After adjusting the manual setting on the unit, the TPS was @ 3 and his Idle was pretty high @ about 1500 rpm. Stay up to date with the latest releases, events, promotions and more. You may have an injector connector that has come loose.A final note that I can't emphasize enough. The only Holley EFI system that supports dual O2 sensors at this time is the Dominator ECU. If that works then try halving them again. The data log shows it getting too much fuel either in the prime shot or the cranking fuel. 4-hole spacers seem to work better than open spacers. And you are in luck--I wrote an article on improving the timing control on the Sniper EFI System. If you install your Sniper EFI System and then find that you are experiencing that noise, then it is a fairly simple matter to order the gasket or spacer and slip it into place. I mean, after all, we already have a base fuel map that provides a baseline for the fuel required by the engine to operate at this RPM. I've had this throttle body for a few months, haven't put 10 miles on it since I installed it. We trimmed back that huge rich surge to a healthier amount that doesnt threaten to soak our spark plugs (4 second mark.) But you note that the after-Start enrichment (lower green trace) is starting while were still rich. Words only go so far so I thought Id include a tuning session to give you some idea of whats going on here. Help for our customers is just a phone call, test message, or email away. Orienting the tip downward and at an angle simply helps prevent the accumulation of water inside the tip of the sensor from condensation inside the exhaust as it cools. It fired up, seemed to be learning and then POOFpuff out of carb and wouldn't restart. I have a aeromotive stealth 340 fuel tank. Would it start & quit like that if the switched wire wasnt working? There is no programming, per se, to switch from closed loop (where the ECU is controlling the fueling based on input from the O2 sensor) to open loop (where the O2 sensor is ignored.) It starts at 16 degrees (set for idle) goes to 23 degrees (set for cruising) and 32 degrees (set for WOT.) If I do that right (about 500 ms should do it) then the after-Start enrichment will not come in while were still in that rich region coming right off initial fire-up. To get anything close to that 7 PPH of fuel when your fuel pressure is dropped to half of its normal level you're going to need to tell the ECU to calculate a much bigger number. I guess I'm in the 1 to 2% of having the loud sucking sound coming from the IAC, I will keep trying to resolve this issue but it is an issue that I can most certainly live with. Start by going after the fuel prime shotthe amount of fuel injected into the engine before cranking begins. Much appreciated! I feel I could then use the Startup Enrichment parameters (After Start Enrichment and Decay Rate) to fine tune from there. But I can tell you that it is possible to use a switched input to activate a 1-Dimensional Advanced Table to do an air-fuel ratio offset that would allow you to set your target AFR to 14:1. Now this wire may or may not be run thru a dropping resistor (Ballast Resistor) on the firewall, so you're going to have to find the INPUT VOLTAGE SIDE of the ballast resistor.Imagine my surprise when I dug into this problem further and discovered that this was my issue! I plan on converting to efi this coming spring. Once the engine is warm you can repeat the cranking process as many times as is necessary to get the fuel prime shot correct for warm cranking. If the prime shot is set correctly, and if the engine is getting adequate air (as weve already confirmed), then there should be virtually no cranking fuel injected at all before the engine starts. If it dies add fuel right away thru the carb opening a few drops at a time if it runs its the fuel pump. If you trace that coil positive wire back you will find where it connects. Looking at the 4500 sniper and I run Super Street 10.90. It is likely that the main power and ground leads are not long enough. Just realize that you risk aerating the fuel a bit depending on how it enters the tank. Tune the cranking fuel in the following locations: Using the Handheld Tuning > Advanced > Advanced Fuel > Cranking Fuel, Using the Software Fuel ICF (Fuel Injector Icon) > Startup Enrichment > Cranking Fuel. Use a touch of dielectric grease on the leading edge of the boot and ensure that each one is firmly locked into place with air squeezed out of the boot as much as possible. Ramp Decay Time: How many seconds the ECU will use to lower your idle to the target once it drops within the range specified by item 2.). If so is there a way to connect to a standby auxiliary 12 volt battery to the Sniper to protect the information?Many thanks,Louis. Starts & immediately dies. Granted, car was not on but still seemed like a lot of fuel to be returning. Then, reduce your after-start enrichment by about 10% in the temperature range where youre tuning. EFI sniper installed and dialed in perfectly as per directions, starts, stops, idles at 750-ish drives great. What is important is that you understand what happens at this point. If it dies again after this it must be a bad coil. Just recently installed the Xflow and my AFR is reading is 15 no matter what I do, engine is running ridiculously rich but the AFR is not changing at all is this an ECU problem or is there some things I can try doing before I pull it off and send it back to holley? Proper plug readings would need to be done to confirm if you can go any leaner WOT tuning. The engine warms up a bit each time. First, remember that after-Start enrichment is not a fixed value. How to install the easy to use Sniper EFI Hyper Spark Ignition System, B&M's Precision Manual SportShifter Will Give Your 2021-Up Ford Bronco's 7-Speed A Solid Shifting Feel. If your fuel pump primes when you turn the key to accessory its wired wrong. My car is going on the dyno for final tuning next week. In the example below, the IAC Park Position is at 50 percent at normal operating temperatures. We do see a massive rich dip in the AFR as soon as engine starts. Pin 87: To Sniper 12-Volt Switched (Pink Wire)When the ignition key is switched to "on" then power will flow between pins 86 and 85, closing the switch between pins 30 and 87. Any help with this would be greatly appreciated.Gary. Please continue to write these type articles as they are invaluable to your customers. to the same number as 4.) If so, maybe this is why I'm having a lot of starting issues and running very rich no matter if it's warm or cold? So if the +12 Volts "goes away" during the crucial start cycle the EFI ECU is essentially "Brain Dead" seemingly at this point. Don't be that guy. Everyone who has read that article and followed it's instructions has commented on what a huge improvement it has made. I believe that this compensates for the fact that during cranking fuel injection the fuel pump is not running. 3.) ), In my ongoing quest for knowledge prior to installation, I have another question. Super helpful and knowledgeable. If so then it is (regardless of what the O2 sensor says.). Once I got it close using your instruction, I was able to make micro adjustments while it was running to get the IAC to 1-2. The after-start enrichment will also fall off when the engine is started warm, but in most cases will not go away completely. That's not the case here is it? That means at or above 55 PSI it is capable of flowing ZERO fuel. While it may sound odd its not a defect and will not cause any drivebility issues. #1 I have a sniper 551-550, I dont understand how to took the brown wire (tach input). But I suspect that's not the case here. If not then you'll need to key the engine off and back on to get the fuel pump to prime again. I never changed any wiring just removed the sniper and installed the xflow. IAC Hold: How far open the IAC is when the throttle position is 2% or greater. Stay after it--you'll make it happen! You see that the AFR trace is ar below the target AFR (pink trace.) Whats the fix? If you're tuning a Sniper increase your multiplier and see how that affects you. Cranking fuel lets us compensate for that drop in pressure. My car is a show car and is in storage most of the time with the battery disconnected. Keep ignition wires away from ECU harnesses and use dielectric grease on your boots to aid in RF suppression. My question is if both of my fuel pumps are wired from relays to my rocker panel where does the blue fuel pump prime wire connect or would you just not use it altogether. (Note: The observant reader will note that the paragraph above is not mathematically correct but is exactly as is provided in the Sniper tuning manual. It just can't work properly.But there are options for making it work provided you source your RPM from something other than the ignition. Enjoy! If you . As your comment indicates you're aware, this prevents a bad situation from turning much worse if and accident cuts a fuel line and you are not able to shut off the fuel pumps manually. Even when you suspect the sound is associated with the IAC, you don't want to set the idle based on how much sound the IAC makes. That is pretty straight forward. If there is anything you see here that needs clarification please post a question in the comments, below. Holley's Dominator and Power glide with 1.80 first gear, 6,200 converter. 2.) Don't hesitate to call, nights and weekends included.). Not perfect but not bad. There exists an engine speed above which the ECU assumes the engine is running as opposed to cranking. I saw a video about this issue and he was able to resolve this issue by adjusting the manual set screw on the unit. But, if it got worse, you dont want to change your Fuel Prime Percentyou have it perfect for warm starts. Will going further help more? Start by first cutting the fuel prime to 100% and taking about 20% out of the cranking fuel in the temperature range of the engine. Do you get an RPM reading on the handheld while cranking? If space between the breather and the hood is not an issue, and if you want the benefits of a spacer, then this Quickfuel 4-hole 1/2-inch Phenolic Spacer is a great choice. I always recommend fixing one thing at a time. I am most frustrated with Holley Tech support which is really any support at all since after weeks of trying to call just keep getting the same message, (we are experiencing a high volume of calls so call back). Your assistance would be greatly appreciated. Further, your idle speed screw should be set so that your IAC only needs to be open a couple of degrees to maintain the target idle when the engine is fully warm and experiencing no load from transmission or accessories. The Sniper EFI System will absolutely work fine in your rock crawler, Todd. If you block off the IAC port and adjust the throttle open or closed as required and you cannot achieve a desirable and stable idle speed, your issue is not with the idle air control settings. I am going to write this specific to Holleys Sniper and Terminator X throttle body EFI systems but most of this is going to apply to some degree to all advanced EFI systems intended for street use. Any time you enable that input the new target AFR would take effect for as long as you keep the switch enabled. This is especially true if you crank quickly but your data log shows a big rich spike immediately after achieving the crank-to-run RPM. I need to get an answer to the question concerning the TPS. All times are GMT-6. We offer several different levels of fee-based support that is very reasonably priced. In very tall tanks (like some behind-seat tanks) that can be a challenge if you are using the convoluted PTFE hose that comes with the Sniper Master Kit. Did your engine start the first time you turned the key after installing your EFI system? Part throttle sucking sounds. Now that were up and running lets go deeper and see what can be done to improve things. Great work! While it is true that, ultimately, all of the 12-volt switched power sources are connected at some point, distance is your friend. They are the only ones got me a holley usb to can cable fast. Would love some feedback as what I need to do to help my issue. This is called the fuel prime shot. Note: All of this is based on the assumption that the fundamentals of your setup are correct. I am having a 2 572 BBC being built for my boat. Don't let that get the best of you. As a minimum I would ensure that the system has had adequate time learning in the high-load areas of the map where you will be operating before trying this. Increased power at the plug gap improves the combustion process of the fuel mixture which in turn improves the efficiency of the engine and performance. Capability Range: Advanced Great article. Awesome Article. There should be no relay added to this wire. Price Point: $$$. Beyond that you can turn your cranking fuel down. Price Point: $, Advanced throttle body injection systems capable of transmission control and more. Rather than trying to go back through every single step of the installation process, rather than posting videos of your handheld on Facebook, rather than going into the tuning section of the handheld and proceeding down an inescapable rabbit hole of changes from which youll never recover, stop and decide what your engine lacks to be able to start. Figure out what it's not getting and the find out why. I have a sniper 1250 with a msd 6014 and a painless rocker panel . Great job implementing what I've written! I know it's only 2 feet but ever inch counts. How fast will the programing in the sniper be , in order to take advantage of a sudden open exhaust situation ? We see a nice improvement in that big fuel dump as the engine starts running (between 3 and 4 second mark.) The Ordering process was so easy and non-painful. Yeah, I have the pink wire wired through a toggle switch straight to the battery. Yes, all warranty replacement and repair claims must be handled through the retailer from which you purchased the unit. Thanks. The Sniper EFI throttle-body drops in place of your carburetor. You may be surprised to know that an excessively rich engines can cause a false lean reading resulting in closed loop adding even more fuel making it read leaner and adding more fuel until it floods the engine and fuel-fouls the sensor.
