There is a harness that is located around your hpfp. It caused my truck to die and would not restart.

Normal idling frp should be about 5k.

Ya I've read that just was curious if 600 psi would start the truck or not thanks for the response

No 600 psi won't start the truck, pcm needs to see 5000psi to start.

thanks for the response I've seen desired rail pressure on scan tool telling me 4500 but i was wanting to think my truck wasn't actually in bad as shape as it was lol pull fuel sample frame shredder valve today and it looked like coffee super dirty idk how it got that bad I'm just in disbelief at this point lol
