no hot start

hi I am new here and need a little advice, I got 95 f350 7.3 and it starts fine when cold but after it warms up no hit, I change the lift pump because it was leaking at the wep hole thinking that would fix it. it didn't, new fuel filter, cannot get my scanner to pull any codes, no data link. checked fuses,okthe truck had been running great until now.could use all the help I can get.

excuse my ignorance to diesel as I am a new owner, but do these have a CPS (crank position sensor). If so I would check that as it would cause a gasser to start ok cold (circuit contacts shrink) and not start warm (circuit contacts separate when warm)

first off most scanners will not do much for the 7.3 diesels, you need something like auto enginuity to actually read whats going on. I would bet on it being the IPR or sensor (on back of high pressure pump) not working after heat soaked.
