I'm frustrated - please help
I just received my AE diagnostics equipment and was able to test the HPO system while cranking. It shot up to 1300 PSI so I think the HPO system is fine...BUT...
Where do I go from here?
While I was waiting on my diagnostics program... I replaced the Crankshaft Position Sensor because it was easy, I cleaned the EGR valve, and I removed the ICP and inspected it and ohm-tested it (804) and reinstalled it.
If I am getting good HPO pressure can I assume that the IPR is OK?
At this point I am pretty much lost...I dont know enough about AE program to know if it can test the FICM for me or if I need to do it with a meter...
From the threads I've read and the notes I've assembled I am wondering about the following:
FICM - Fuel Injection Control Module
ICP- Injection Control Pressure Sensor
IPR- Injector Pressure Relay. It is what controls the pressure from the HPOP to the injectors
PCM - Powertrain Control Module calculates the proper idle speed for conditions
IDM - Injector Driver Module – Amplifies the voltage for the injectors
