Hey guys,
Ive been diagnosing this issue with my 94 f250 7.3 N/A. It is a pain in the a$$ to start after having sat for a little while, usually several days to a week at least. Truck has 158K on it.
The issue is: The truck sputters and coughs while trying to start, feels like partial combustion, billows grey smoke (unburned fuel?) usually for a solid 20 or so seconds. Sometimes longer, other times it actually starts easily.
I have installed new fuel filter, electronic fuel facet lift pump, replaced all my return line caps, O rings, lines, clamps etc. I just installed a new GP harness from Classic Diesel (looks awesome btw) since my old harness was falling apart. Killed the batteries yesterday trying to start it after the harness install so I am guessing that wasnt the main issue. However, I juiced it back up today and it started after ~4-5 seconds of cranking.
I believe my injectors and pump are original. Replacing the pump isnt a realistic expense right now due to the virus outbreak and what not.
