How EFI travels its fuel from the tank to injectors?
Electronic fuel injection (EFI) The fuel exits the fuel tank via the fuel pump. It travels through fuel lines towards the engine. The fuel pressure regulator constricts the flow of fuel and only lets a calculated amount through to the injectors. This sensor tracks how much air is entering the engine at any given time.
What is the diagnostic code for fuel injector?
If you run the diagnostic mode, via turning the key off/on 3 times quick, you will usually get an error code 51 with this problem. Code 51 is ‘fuel injector #1 short to ground, short to battery, or open load’.
Why is my fuel pump not working on my ATV?
The engine crates a vacuum pulse to the fuel pump, which in turn creates an amount of pressure that pushes fuel into the carburetor. If you’re not getting good suction, try replacing the diaphragms in your fuel pump and make sure your vacuum lines aren’t cracked.
What is the problem with my EFI plug?
It can load up the plug and foul it. The problem is on the coil. The dual coil is mounted to a panel inside the front left fender well. There is one bolt going through the center of the coil mounting it to the panel, which mounts to the frame.
What should I do if my ATV is not getting fuel?
Try starting the engine for at least 20 seconds. If it does start, don’t let it run for longer than 20 seconds. Then you want to sit and wait about 10 minutes or so. You need to give the fuel injector cleaner time to do its work. Repeat the process five more times, but only try to start for 10 seconds, and then let sit for ten minutes.

What to do if your EFI machine is sputtering?
You can also (with the machine off), grab the coil and see if you can rotate it….if you can rotate it, then the ground, mount bolt is loose and needs to be tightened. In order to tighten, you need to remove the two bolts on the mount plate. They screw directly in to the frame.
