awhile shuts fire and feul pressure have rebuilt distributor


Posted on Feb 5, 2014

after it sets for awhile it runs for a couple seconds you can see injectors pulse then shuts off and no injector pulse does have fire and feul pressure have rebuilt distributor and replaced eec. You need to verify you are getting spark when you loose injector pulse. If the pcm doesnt see any engine rpm signal it will kill the injector pulse. Verify

the check engine light operation when the problem occurs. The light should be on with the key on and go out when cranking the engine. When you typically lose an injector driver in the pcm the noid light stays lit, Sounds like you have a wiring problem between the pcm and the injectors. Really hard to tell you where to look on this type of concern. You should at least have power at the coil and the injectors. The pcm grounds the injectors to cause the light to pulse. i do have power at coil because engine still has spark when it looses injector pulse ijust went back to start and it started and ran for a few seconds then shut off. i will check tomorrow again with test light to see if i have power to injector my noid light would only be showing pulse i could still have volts to injector but no ground ie driver. noid light needs both to work. Ok you have two main wires for the injector driver circuit one is Tan/Orange and the other is Tan/Red see the schematic below. Either you have a broken splice point or a open circuit, bad connection at the pcm for the driver circuit pins 58 & 59 in the pcm connector.
