99 f350 wont start

[maxx]

my truck started great yesterday after it warmed up i started to drive as i did it spuddered then died and would not start. I replaced the glo plug relay, also the cam sensor, the fuel filter, put five gallons of new fuel in the tank and bought new batteries. I have checked all the fuses they are fine and i know that fuel is reaching the filter when i try to start it. the engine turns over but will not fire. i am at a loss at this point if any one has any ideas i would be very greatfull i feel lost with out my truck.

are you getting codes. or ses. is your high pressure oil pump full of oil. check that and see if its full.

my hpop is full, as far as codes i am waiting for my friend to come over and check my pcm. thank you for your reply i will post what he finds out, in the mean time any other suggestions would be much appreciated

Does the wait to start light come on with the key? If not then it may be a bad computer or power loss to the computer.

thank you my light did work and upon further inspection i have found the problem. it turns out that my fuel/injector pressure regulator had died so the engine was not getting any fuel. thanks for all your ideas.

Just out of curiosity was it your fuel pressure regulator not letting it get fuel or your injector pressure regulator not letting it get high pressure oil? How did you find it and fix it?

sorry for the delay in responding. it was not getting enough oil pressure to move the fuel, i need 550 psi and i was only getting 35 psi. i found it by checking the pressure then fixed by replacing the ipr and also the pressure sensor. it starts great and runs good nice to have my truck back.
