Question about 1995 Ford F350
Took the vehicle to repair shop and they have replaced the high pressure oil pump (3 times) an the IPR valve.
When the vehicle would not start prior to have towed in I removed the fuel filter atop the engine and stuck my hand down in the diesel fuel and found a wire, pulled the wire and it seemd attached, gave it another small tug; it came out and had a connector on the end of it. It appear the other end had been soldered to the housing some way?
The repar shop is still getting diagonstic code indicating the high pressure oil pump and have replaced it three times. Could this wire be some type of sensor keeping the high pressue oil pump from working. Are you familar with the wiring in the fuel filter housing and what the wiring could be going to. Repair shop said they could not find a place for the wiring or where it would go. It is a repair shop that until recently only worked on diesels. I have been using them for years with good satisfaction......unfortunately they have had the truck for over a week now and three pumpls later I have a growing concern.
Could be camshaft sensor, easy test, Crank engine over and watch the tach on the dash. If tach does not move engine will not start. Also I had Bad wiring for my fuel filter housing heater circuit. I found a cool website www.powerstroke.org. This site has tons of information on 7.3 in its forums. this is a free website although you may need to register. Hope this helps. I've been there.

I have a no start problem with my 1995 7.3L and checked the wiring connectors to the valve cover gaskets to the injectors. One of the terminals (out of five) is burned out on at least two connectors. I'll replace both gaskets and repair the connectors and let you know if that fixes it.
