I have a 1995 f350 crew cab 2wd with the 351w. It idles fine and will drive for 30 or 45 minutes, but then chokes and will not go over 50 mph. I have replaced the fuel pump, filter, distributor (the whole thing), ICM, coil, plugs and wires, throttle position sensor, and fuel pressure regulator. I'm at a loss here. Fuel pressure was fine at 40 to 42 but now I can't even get a reading. I tried a different gauge and still can't get a reading, but it's running fine so I have to assume it has pressure. If I press the valve, it shoots up at least a foot. Any help or ideas is greatly appreciated. Oh, we put a new catalytic converter on it as well. Do I need to reset the computer after the cat install??

 

Pull codes and post up what you get.

 

I checked the codes multiple times through all that and never got anything other than the EGR code that has been there since I deleted it.

 

Have you deleted the air injection system too?

 

No I just deleted the EGR cooler.

 

Man I have 2 separate threads going on here. I got confused. I have NOT deleted anything on this truck. I'm looking for help with my 6.0 diesel too, I should have paid more attention to it. Now I did pull the codes on this 1995 as well, I get a 111 or pass every time.
