Can a fuel injector stick wide open on a Harley?
Yes, that could happen. But if an injector sticks wide open, a TON of fuel would be going in. Fuel would be dripping out the pipe when it was going down the street, You could always swap injectors and see if the front spark plug now goes black. That would be a quick and dirty way to test it.

How does the fuel injection system work on a Harley Davidson?
Ion Sensing System – This system uses ion-sensing technology to detect detonation or engine misfire in either the front or rear cylinder by monitoring the electrical energy at the spark plug after every timed spark.
How do you turn off the fuel injector?
1. Turn the ignition key to “Start,” but do not start the engine. 2. Set your multimeter to measure volts. 3. Disconnect the electrical plug from the non-pulsing fuel injector. Pull the electrical plug and wired lead away from the fuel injector to allow access to the metal tabs in the plug. 4.

Is the fuel injector on my Harley Davidson bad?
Rear injector replaced about 8k ago (took the HD mech 5 hours to figure out the injector was bad, another 3 hrs on the dyno to tune afterward). Now the symptoms are back again- OK acceleration, but misses during steady speed, fuel mileage down, backfires and pops.

What are the symptoms of a fuel injector problem?
Now the symptoms are back again- OK acceleration, but misses during steady speed, fuel mileage down, backfires and pops. Took the plugs out today, the rear plug is fouled.
Can a lack of fuel injector cause a backfire?
Lack of injector would not cause backfire and pops but erratic spark would. Don’t jump to conclusions like an ECM. That will cost you a lot of wasted money. Have you checked for any DTC’s. Have you tested the resistance in the plug wires or replaced them to try to isolate the problem? Fouled plug is missing ignition, not fuel.
