Alright guys, I think my fuel pump may be going out but I'd like to run it by yall and see what you think and also which parts to check out.
Key on fuel pressure (no ignition): first turn will put it anywhere from 15-25, second turn will kick it up to 35ish and then the car will be able to crank. The pressure will also bleed down very fast, in 10 seconds or so it will sit at 0 psi.
Idle fuel pressure: 32 PSI
Idle fuel pressure with FPR line disconnected: 43 psi
I pulled the fuel rail and saw no fuel leaking down when key turned.
The pressure does not increase even under WoT but under WoT there is no surging, bucking, bogging or any driveability problems.
The car will also surge under constant light acceleration.
