HPFP failture?

335iJWC · 01-03-2012, 12:51 AM

So i was on my way to a buddies house when my car turned off at a light, I turned it back on and car ran fine for the next 5 miles, when i was parking, it stalled and turned off again, turned it back on this time it cranked for like 2 secs,
parked it and 6hrs later the car wont start it just cranks i just got a ride home, will take my lap top and read codes tomorrow.

ive had 2 HPFP failtures but it was with limp modes and long cranks only when cold.

could this be the the LPFP failing?

Without codes, it's a guessing game.

This morning the car started right up with no codes from the JB4, after idling for like 10 mins the car turned off and now wont start, its only giving me one code " 2e8c intelligent battery sensor function."

The car turns over fine but wont start i tried to jump start it but nothing changed.

If I'm not mistaken, only the dealer can reset that code; I think it's some type of fail safe. Did you leave anything connected to your OBD port or somehow drain your battery? Have you done anything to your steering column? Either way, I'm pretty sure the only fix is to have the dealer clear that code (and get to the root of what caused it).

No nothing should have drained the battery and the car turns over.

it turned on again im running it on map 0 and will remove the meth pump, JB4 and take it in to the dealer tomorrow. Ill have the check the fuel pump as well.

Here is the code list i get, the car would just shut off at idle and only stay on if above 1500rpms

I replaced the Intelligent battery sensor with the negative terminal cable, but the problem persists
