Hard warm starts
HI. I'm new to this forum but not to the powerstroke. I have a 94,180,000mi 50hp chip mostly stock work truck. About 3 weeks ago I started having hard warm start issues. Pulled the IPR cleaned it, new o-rings and went to a real hard start and running bad. IPR was sticking so I got a new one from ITP deisel on e-bay. Put it in and got good start and good run but I still have a hard warm start issue. Sometimes a good clean start sometimes a hard start. HPOP is not leaking down. I can not pull codes yet because I need a newer PCM so I can get the codes with my AE code reader. I am having a hard time finding a newer PCM. Any ideas on what I can check until I can get codes would be apreciated. What are the chances of a bad IPR?
