Stange fuel problem.....
 

I'm looking under my hood when my car is running, mind you this is at idle, and my guage is pegged at 45psi @ IDLE!!!!! worked the throttle from under the hood and gave it a quick rev, stayed at 45psi, when i turn the car off, it goes down to zero. checked everything fuel related, return, FPR, filter...yada yada yada. my guess is it's just the guage, cause i put the stock regulator back on and it was still pegged at 45psi. any clue?

forgot to mention i have an AEM FPR, took it apart and the diaphragm was fine.

or if nothing else rewire the shiznits

rewire what?

up

vaccum leak... been there done that... where is your car idling???

First of all, please, turn "caps lock" off, and second, there is no wires on an underhood fuel pressure gauge....

does it studder when you try to start it?

yep sounds like a leak to me too...

leak..............check all the vacume lines for any cuts or holes or maybe even came off but i had a small hole in mine before and it did the same thing
