ok this is the deal, went i start the car(if it starts) it idles normal then after a few minutes it dies. ok if i rev the engine which will only go to about 3500rpms and then let off it starts to choke and dies. so far i was able to eliminate the bov,vac. leak, and the engine itself(compression is in normal specs) what else should i try? it kind of sounds like the engine isn't getting enough fuel but pressure is constant and never goes under 38psi plz help as i just put over 15k in this car and i can't even drive it

can you rev over 3500? any check engine light?

it is not the fuel pressure and check your FMU/aux pump connection and make sure you are hooking up to the correct hose. tapping to the wrong hose at the wrong direction will make the car die. esp when the boost kicks in.

check for all connection again for leaks and make sure there's no crack or anything on the rubber 90 degree bends.

i will check the fmu and fuel pump this afternoon but yes it will not rev past 3500rpms what would cause this?

Doesn't a blown maf sensor show this symptom?

You're not giving us too much information. What year is your car? Have you checked for CEL codes? Is your maf sensor before the blower or after in the intake tract?

Also, when is the last time you replaced your fuel filter? If it's been a while, replace the filter first and see what happens.

sounds like MAF....but usually MAF will throw you a code which he didnt see.

I remembered that one of the 90deg join fell off my car and I could still rev up to 4000 rpm. but the car will die once I let go off the pedal and all the warning lights will show up.

but if he hooked up the FMU incorrectly and once the boost kick in (around 3500rpm) the car will shut off too.

you may need a new maf sensor, that is what i think. with a blown maf sensor, you are not able to rev to high rpm's. sucks because i know those maf sensors are pretty expensive, im guessing maybe around 4 bills.
