:dunno:
I have a 96 F-350 7.3L with 149k miles on it. It has been running fine, but 2 days ago it suddenly refused to start. It has 2 new batteries and spins over good and fast. It tries to start, but acts like its only hitting on 3 or 4 cylinders and has a loud fuel knock. This is what I have checked so far:
Cranking fuel press. is 60 psi.
Oil reservoir is full.
VC harnesses checked good with ohm meter.
New fuel filter.
No check eng. light on or trouble codes present.
New glow plug relay, haven't checked glow plugs yet.
Disconnected right bank inj. harnesses. Won't even try to fire.
Disconnected left bank inj. harnesses. Will try to fire but won't start.
I should also mention that when I am cranking it I have a battery charger hooked up to assist the batteries and
it is inside a heated shop out of the cold.
I am leaning toward the IDM being the culprit. I am a heavy truck mechanic by trade, but have no experience on the Powerstroke fuel system. Am I on the right track or am I way off base? Any advice would be greatly appreciated.
I have a buddy that owns a salvage and can probably borrow a used IDM or other parts to use for diagnosis. Thanks.
