Thanks Muc!!! I will check this wire as soon as I get home.
muc He earlier said he put fuel into the throttle body. Does he have TBI or MFI?
That's an interesting thought. My guess is that it would be possible for the TPS (throttle position sensor) to stick at 100% and cause the ECM to go into clear flood mode. This is something that might be able to be checked by unplugging the TPS and cranking the engine with a noid light (this is the name of the light that your tech hooked up when he tested your engine) installed and seeing if it flashes. This is because most --- but not all --- ECM's will insert a default value when they detect a fault with a sensor. The way the ECM sets a fault on a sensor like the TPS is that it is looking for a voltage reading from the TPS between .2 and 4.8 volts. If it senses a reading outside of that range it will reject that reading as impossible, set a fault code and insert an in range value so the engine will run well enough to get you home. I'm 95% certain that your ECM will do this for a TPS fault. You will need a noid light to test this theory (a voltmeter won't work because the ECM give the injector a ground for milliseconds at a time to fire it and a voltmeter won't react fast enough to read that short of a electrical connection) you can probably buy a noid light pretty cheap at an auto parts store,Your last post might just hold the clue as to why all 8 injectors stopped working. I think you need to check the function of the "anti flood" sounds to me that it may not have reset.
Yes on some engines. I'm pretty sure not on this on. Would need to look service or owners manual, the engine or wiring diagram to be sure.Does VP use a clean power feed ?
