When I rebuilt engine I put same hpfp back in that came out still hard start so then I replaced the hpfp hard start went away for about 1 week then came back. new hpfp new injectors new lines new filters New gasket and wiring harness.

Welcome, I am Chris (aka-Moose)

Any trouble codes stored?

Have you monitored the actual and desired fuel pressure on a hot restart?

Once it starts does it misfire, run rough, smoke?

No misfire. Just hard start when hot but when it fires up it sounds great and runs just fine. Haven't checked codes yet.

Will you be able to perform the 2 tests I mentioned?

Expert:  Chris (aka- Moose) replied 1 year ago.

As mentioned in my first response, I would stay in contact with you. I've noticed you have not rated the post. So I assume you were not pleased with my help. I hate that you have spent money to get an answer but left not happy. Can you tell me why, or can I help more. If its more help you need just reply and we can pick up where we left off.

Sorry not on here much I drive semi for a living. No I can't do the pressure test because I don't have a scan tool to check it. Been calling around trying to find a scanner that will do it.

Being that you are not able to perform the tests needed. How do you feel I can help you so you will be happy with my assistance?
