no fuel pressure ?

I am new to this so if i am posting this wrong i do apologize . I have a 2006 mustang gt . when car is sitting still the rpms flukuate just a little , but if i turn air on the rpm will drop to 0 and kill car when clutch ingaged. I checked fuel pressure and fuel pressure is only at 35 and when acceleration givin the rpm actually drop instead of getting stronger . I have replaced fuel pump and fuel filter already . the only code the check engine light is a cam postion sensor, but ive heard that other people thought that was the problem and it was not

Re: no fuel pressure ?

35psi is about right at idle, could be a bit higher, but shouldn't be your problem. I wonder if the 4.6's have a fuel pressure regulator? could be an issue. I'm not familiar with the 4.6. Does the pressure drop when u give it gas?

Re: no fuel pressure ?

yes it has a fuel pressure regulator but it is actually built on the fuel pump. so you can say it has been changed also i guess . the pressure does drop when you give it gas

Re: no fuel pressure ?

has it been modded at all? i was really expecting an older car when i said the tps... still could be a possiblity, but i wouldn't suspect it on a newer model...

when did this all start? had anything changed around the same time this started that you can think of? maybe something within a couple weeks?

Are any of your lines crushed or kinked?

Could be a leaking injector.

Re: no fuel pressure ?

your fuel pressure (if similar to 99-04) is right on. Autometer tells me 25-40 psi at idle.

The top gauge is my fuel pressure gauge.
Your fuel pressure should react like that. I'm not sure how you're measuring it (Schrader Valve and throttle blip?)

Re: no fuel pressure ?

I am testing fuel pressure by disconnecting the fuel line from fuel rail and hook it up that way. I do not have a schradier valve

Re: no fuel pressure ?

not that i have noticed , just got it back from the ford place . they changed throttle body and a sending unit. 660.00 dollars. the throttle body did fix the problem with my car dieing when air is on when i am stopping . but did not fix my hesitation.

Re: no fuel pressure ?

He's talking about a hand held programmer. Probably my next investment..
