Sometimes it will start right up, sometimes you have to cycle the key once or twice. When is won't start, it will just crank and crank, no smoke, icp goes up to 2500. Then if you cycle the key, it will start up like nothing happened, then others times you have to cycle the key again. It did this about 3 years ago once, and then never again till about 6 months ago, idm was shot so i replaced it. It took care of the problem, then about a week ago its doing it again.
No codes. I never took the chip out and tried it, because it doesn't do it all the time. I thought maybe the pcm needs to be re-tinned? You can see some copper, but its been fine for a while, why would it start acting up now?
Sorry for the long post:(

Fuel pump losing prime (bad check valve)?

Do you have access to a fuel pressure gauge to verify?

No, No fuel pressure gauge, yet. I have dual fuel pumps, so if one was acting up, it should get enough fuel with the other.
