With the 3.1 engine: Ignition on 52-59 psi, at idle 42-56 psi. With the 3.8 engine: Ignition on 48-54, at idle 38-51. Let me know if your's is supercharged the specs maybe different.

Were is the fuel filter on a pontiac grand prix v6 located


The fuel filter on this vehicle is located inside the fuel tank and is part of the fuel pump module. It's supposed to be a lifetime filter, and most of the time they are, but if it should ever clog then the entire fuel pump module has to be replaced.

Car starts up and idles fie but when i give it gas it dies out. i replaced the fuel filter map sensor sparkplugs


Sounds like fuel pump, you need to have it check with a pressure gauge. if you have a 3.3 in that car the pressure is suppose to be 40.5 to 47 psi.

My 2001 grand prix will turn over but not start up


I would check for fuel at the test port on the fuel rail. Also check for spark at the plugs. You could have a bad fuel pump or igntion control module.

Where is the fuel pump cut off switch located on a pontiac grand prix se 1997?


There is no fuel pump cut off switch in General Motors vehicles.If you don`t have fuel pressure or the pump is not running you have to check the fuel pressure with a fuel pressure gauge.You can check the fuel pump fuse and make sure it is good.Hope this helps.Good luck.

What makes a car stop while driving but starts


Fuel pressure loss is the usual cause. Check your fuel pressure. This can be caused by a plugged fuel filter or a faulty fuel pump. The next thing to check is your fuel pressure regulator

2001 grand prix starts and then dies right away


Check the fuel pump inline resistor located on the right side front fender between the frame and the windshield washer fluid canister. When this resistor goes bad those are the symptoms.

2001 Grand Prix cutting out


Sounds a lot like a fuel rail pressure issue. Re-check your work. Make sure your supply AND return fuel lines are not pinched or kinked.(that won't cost anything) Put a $15 NAPA Gold fuel filter on. At eight years you can't go wrong-it should need it anyway. Next step up in price is to have a mechanic attach a pressure gauge to the Schrader valve and monitor rail pressure as you drive and reproduce the stumbling. I'm betting your mixture is getting FUBARed causing your PCM (computer) to pull timing, that in combination with the low octane gas is causing your mixture to ignite so late it's still burning in your exhaust system. Retarded ignition timing will cause MASSIVE losses in power and dangerous under-hood temperatures. The reason I say dangerous is the GTP engine fire recall situation. http://www.gminsidenews.com/forums/f33/upcoming-recall-07035-97-03-gp-regal-3800-s-c-vin-1-a-61961/
If you’re throwing half burned gas down the manifolds and into the catalytic converter, it will overheat (and glow red or orange) and the internal lattice will melt and collapse (may have already happened) this will restrict the exhaust badly and cause a further reduction in power and more knock timing ******.
LMK what you find after the filter or fuel pressure test. That will tell you where to go from there.
