hi sorry for the delay i just got back from my holidays
umm what is the CKPS and the ICM?? how can u test the ECM?
and well i tested the fuel system i put a fuel pressure gauge on the rail and i turn the key to on it goes up to 60psi but then drops down to 0 i read in my book can be a regulator or pinched lines etc or even a leaking injector
basiclly i know i can replace the regulator easliy but how the heck do you know ur injector is leaking or how to test for it?
