Car bogs when gas pedal is pressed

[silverarrow27]

I'm getting similar fueling issues with mine too. Been battling it the last couple months on and off. My car is rough at first start up and have to keep the throttle open for several seconds until it catches and idles for a minute or so then stumbles and dies. I can't seem to rev past 3-3500 rpms on my car like a bad MAF, have replaced the MAF & FPR/gauge thinking it may have been a combination of all three.

Nope, fuel pressure still stays at 0. Previous gauge was a B&M and current gauge is a Marshall. Previous FPR was an Aeromotive A1000 & now have an Aeromotive 13129 EFI Bypass Regulator. Starting to think it's my fuel pump because I can't hear my fuel pump prime anymore when my key is at acc.

Thanks for the tips S14DB, done a couple of your suggestions already. Will do the other ones which I have not.
