Fuel Pressure Regulator gone bad? Good Aftermarket replacement?
 

I've been having an issue with my car where it will start and almost immediately die. Finally getting around to checking the fuel pressure. It seems to be good at the pump (~95 psi), but just after the regulator it is next to nothing...when you start the car it goes to 40, then almost immediately drops to 20, then the car stalls and dies.

Is there anything else that could be causing this other than the regulator? I've been wanting an aftermarket regulator anyway, so this may be a good time to get one. What are good aftermarket units to use? I've seen universal ones such as the AEM one, but I don't know how much trouble these are to install. Are the universal ones a good choice or is there a kit made just for the TII? What do you guys recommend?

I use the AEM universal, and I think its a great unit. Not all that much hassle to install, but you would do well tojust do the parallel fuel mod while you are at it.

what is the parallel fuel mod?

Uhh.. Re-Teds parallel fuel mod.. Its on his site.

I'll check it out. If I don't go the route of doing the parallel mod...would the AEM universal kit come with everything I need to do the install?

From what I recall when I got mine (it was a while ago), it was just the FPR. I had to go get the associated fittings myself.

gotcha...Let me ask this and see if you guys think it could be something else causing these symptoms. The car ran fine, did a FMIC install, and now the car starts and then dies...if you try and give it any gas, it just dies faster. I can't find any vacuum leaks, and the afm is plugged in (that were the first 2 things I could think of). The fuel pressure when checked is as stated in my first post....good at the pump, but at the regulator...it is 40, then drops to 20, then off to nothing and the car stalls. I really hate to think it's the regulator because it would be a heck of a coincidence that it happened to crap out just sitting for a week while the fmic and piping were being installed. You guys have any other ideas before I invest in a new regulator?

*******), but just after the regulator it is next to nothing...when you start the car it goes to 40, then almost immediately drops*********

Anything after the regulator is just fuel returning to the tank. Either your not checking the pressure right or not stating how your doing it right.

A guage tee'd into the fuel hose b/t the filter and where that hose attaches to the engine would be a reading of the fuel rail pressue which should be approx 28-32 psi at idle and 37psi at idle if the vac hose is pulled off the FPR.
