Cant rev past 5200 rpms....

[no1sirbutler]

I have no clue what is going on w/ my car. Its a 2001 gt w/ a KB, 5spd and the normal bolt ons. Took it on a trip this week and all of a sudden I cant rev past 5200 rpms. it literally falls on its face and feels like it dies. It seems to run fine up to this point as well. I have no CEL either. I also have a warm starting issue. I have the 03/04 cobra fuel tank and pumps and have deleted frpv in the tank. I used to just have to cycle the key and it would start fine, now I have to cycle it 3 or more times to get it to start. If the car is cold, it starts completely normal, after its warm its just cranks until i cycle the key a couple times. Any ideas whats it going on here?

Sounds like the fuel pump may be going out on you. Do you have a fuel pressure tester or an sct hand held?

I do have an SCT hand held....xcal2. Im pretty sure I can get a hold of a fuel pressure tester. I do have a fuel pressure guage in my car though w/ the sensor in the fuel rail.

Is fuel pressure dropping when your wot?

Is fuel pressure dropping when your wot?

Ill check that when/if I get home....currently at Myrtle Beach and heading home in the morning. Once Im closer Ill do some WOT pulls and watch the guage.

Ok checked my fp gauge.....fuel drops off suddenly the rockets past my normal high after it falls on it's face. So I'm guessing it time ton upgrade fuel systems. What do you guys suggest?
