When the key is in the on position, not cranking, the injector is spraying a constant "shower" (not a light mist) of fuel into the throttle body. This fuel spray continues until we crank it. No start. As I turn off the ignition the injector acts like a toilet and continues to shower nearly a 1/4 cup of fuel onto the closed butterfly valve.
I have switched out the injector and the engine turned right over. As soon as I turned it off and tried to start it again the problem returned.
As I studied further I realized that with the ignition in the On position there is an inconsistent rattle/clicking sound coming from the injector, and I can feel a vibration in the injector in time with the rattle/clicking noise.
I unplugged the injector electrical wires and tried cranking the engine. The was no clicking noise or vibration. With the key still in the on position I plugged the wires back in and the rattle/clicking and vibration DID NOT return. I was able to start the engine and it ran smooth for over an hour.
I turned the engine off and let it cool. When I went to turn it back on, as soon as the key was in the on position, prior to cranking, I could hear the rattle/clicking sound and the engine failed to start, and the excessive fuel shower returned.
have the same problem?
