Ive been having this weird problem with my car since I installed the 255lph. When the car is cold, it will pull like a freight train (until the rr runs out) and see around 61# of fuel pressure. But, as the car starts to warm up, the wot fuel pressure will drop off the warmer the car gets. Im baffled by this and praying that its not the wiring showing its age. Does anyone have a clue whats happening?
No one? Do you think that using the crimps that came in the kit instead of soldering everything could be playing a key role?
The electrical gurus (not me) recommend soldered connections. You could always measure resistance cold and then hot?
Your sign doesnt say anything about a afpr I may have overlooked it though. Your reg might be giving some trouble? "maybe"
Is your boost dropping also??? I wouldn't expect the fuel pump to be loosing pressure with heat, maybe the FPR is being affected?
Oh, yea, sorry. I have the kirban afpr. And a cyberdyne digital gauge fuel pressure gauge.
