Re: help me no injector pulse!!!!!!!!!!!!!!!!!!
Hi, no injector pulse eh, bunch of codes, i'm guessing that they were is memory, or were they hard faults, Crank signal of course should be checked but dont forget all ecu grounds first, they are ultimatley your injectors ground.
even if codes can be obtained, the fact that their all low voltage codes maybe tells us theres a ground problem somewhere. Engels statement was true it could be also in the pcm.
Getting the spark could tell you everything, spark is obtained by the cranksignal as well is the basic injector pulse. Spark then means the crank signal is working and most likely it would be the injector drivers (pcm) or pcm grounds.
I have seen a good spark and no injector pulse on fords, honda, and holens(gm) and all have lead to a pcm ground, but check its voltage as well.
I trust you used a noid light or led test light to check for injector pulse.
