electrical issue in a 2002 f250
I'm tryin to help a guy out and fix the starting problems on his sons psd. after work on the side. I have no books on this unit at all and the 2002 seems to be it's own breed of cat.
I have found the grounds at the three pins at the pcm go open with the key on.
Is this normal? last i knew a ground wire was grounded at all times. This is g101 in wich i am referring to. the pcm was bad-had a burnt transister in it. 4wd module was burnt also.
as a side note, the dome lamps dont work either.
originally thought there was a problem with the glow plug system but the pcm is not activating the glow plug relay. i have printed a lot of material from ford, but there is no symptom code for this concern that i can find.
The idm relay also buzzes continuously with the key in the key in the on position.
PLEASE guys, point me in the right direction.
