So I've got an early 1995 model 7.3lt Powerstroke with VIN engine code K. Just got this truck, it would only run for 15-20miles and then die. Would not restart for 30+ min afterwards, then run rough for awhile. So I'm new to working with diesels and thought this would be a great opportunity to learn. All I can say is I quickly got over my head.
So he is what I did to the truck..
1. Replaced all the injectors and injector cups. Pressure tested cooling system to 15psi after parts install. No fuel in cooling system. No cooling in oil.
Seems everything went well with this part.
2. Replaced HPOP and IPR. These were 94-95 version parts. Purchased Bosh pump with matching IPR from same source. Replaced worn looking hoses
while I was working on this. Using IPC port I was able to read I have over 1000PSI (only have 1000PSI gauge). I cracked open hoses while under pressure
to try and bleed out any air.
3. Replaced all fluids and filters. Oil, cooling and fuel. Do not have any signs of fluids mixing. I also pumped out the HPOP tank and refilled.
4. Replaced the IPC Sensor
5. Replaced the CPS
6. Replaced the temp sensor next to the water pump. (it had a minor leak).
7. Replaced both of the valve cover gaskets. Both left and right sides had melting of several of the glow plug connections.
When I replaced these I also installed new pigtails of the engine wiring harness. I soldered each wire, insulated the connection with heatshrink tubing.
Each wire was then ohmed with a meter from the end of each wire to the engine wiring harness connector. Verified wiring color codes with each wire
going to the correct device.
8. Replaced both batteries and the starter.
So, I have cranked on it a bunch of times, the engine sputters but never keeps running after the start stops.
First few times I cranked on it, fuel pressure only went up to 10psi. A few more times got it up to 20psi. a few more times its now to 40psi.
That just seems low to me, that fuel pressure should have come up alot faster then that. But I dont know.
Any guidance anyone can offer would be great. Thanks.
