Need electrical help
I have a 95 3.4 5 speed and my injectors aren't pulsing so I disconnect the injector harness from the main harness so I just have the one big plug ok so I tested my driver side bank with 12volts from the two pink wires from the fuses and one fuse was gettin no volts when I tested each injector driver wire on the same side of the harness then I checked the other pink wire and I was gettin a ground from it and I ran a new wire and I still have no injector pulse my cam signal doesn't even fluctuate and ideas the car has been down for five months
On the injector plug, one side is relay controlled battery voltage. The other wire goes to the PCM.
When inj is not commanded open, battery voltage goes to the PCM.
When inj is commanded to open, PCM places a low onto it, but not ground, from its quad driver.
This difference in voltage opens the inj.
The PCM splits the crank sensor signal for ignition timing/spark and also for injector commanding.
