95 t-bird will not stay running,help!!!

[theevilmexican]

i brought a 95 t-bird for my son which he wil need for school soon.it will start fine but after about 5-10 mins it will stall out.i have changed the fuel filter and the fuel pump and the inert switch,but it still continues to stall after 5-10 mins.and will not start untill about an hour.

Did you check the fuel pressure at the rail? The fuel pressure regulator may need replacement, too.

Also, when it dies, can you start it again with your foot just barely holding the throttle open? If so, the Idle Air Control valve is the culprit which is mounted on the intake plenum.

well i am getting fuel to the rail.it will start again but for a min then stalls.when i try angain it will not start,after a while it will do the same thing.i guess it only starts when its cool.

[theevilmexican]

well i just tried it again and it started just fine but after a min it stalled.when i tried it again it started but when i pressed the gass it stalled again and would not start gain evenif i just gentaly pres the gas it will not start until after a while.

Just a guess, but perhaps the fuel tank isn't venting properly. without refreshing air into the tank an immense vacuum will result and choke out the engine.

if there was a vent/vacuum problem, then the car would not be able to start again until vacuum was eliminated. do you hear suction noise when you open your fuel filler cap? do you hear your fuel pump noisily whine just before the engine cranks? is there alot of black smoke immediately upon starting?

If it was a gas tank vacuum issue you can identify it when opening the gas cap. You will hear a rush of air as you open it. You can even try running with the gas cap off but it will probably set a code, just be aware.

You may be barking up the wrong tree. It may be an ignition problem instead of a fuel delivery problem. Have you checked for spark through the plug wires when it won't start? What engine do you have?

[theevilmexican]

i have a 4.6 i dont hear any air rush in when i checked the gas cap.i check each plug wire while the car was running and i get sparks from each one .shock me of course

You have to check for a spark when the car won't start! A clamp on timing light will save you from a shocking experience! As Blue)(Fusion said, check the fuel pressure with a gauge at the fuel rail. See if the pressure drops just before the car stalls and won't start.
