I have a 95 f350 powerstroke and very recently starts no problem when motor is cold, runs great until I shut if off. Doesn't matter how long I run it but once I shut off the key and try to restart, no good!. Cranks but no start. Disconnected the glow plugs and tried sniffing either and fires right up. So not getting fuel, no codes present. Once it cools down a little starts right up and runs great. Changed the cam position sensor, had this happen over the years and was cheap enough and same thing. Changed recently the mechanical fuel pump in the V a couple of weeks ago as it was leaking. Ran great and was saving fuel, lol. Feel it might be a sensor, something telling the injector pump not to pump giving it a false reading. I have a 133k on truck and second owner since 96'
