Go with failed fuel pump, until you know how to test it.

It is seizing up mechanically or electrically

Check things HOW?

You need fuel pressure gauge,volt meter,oscilloscope
& such, to do testing,as well as wiring diagrams

SOURCE: I have a 1997 Pontiac sunfire 2.2 engine,

why was the sub frame replaced was the car in a wreck? i would check and see if any grounds were left off or broken.next test for a vacuum leak at intake. and or vac. hoses installed incorrectly.if you have a large library in your town you can look up repair manuals and look for a vac. hose routing. you should also perform a fuel pressure test.and yes you could have a bad crank sensor,which would cause your symptoms.i hope this will help you.

SOURCE: 1996 2.2 liter. Starving for fuel

There are a few other things taht could be causing fuel starvation. First of all, did you pull the injectors and clean out the individual filters? There are small, conical screens inside the top of each injector, and they could be clogged. Second, There could be some carbon build-up on the intake valves, which would act like a sponge for the fuel after initial start-up. A can of BG44K fuel system cleaner from NAPA will get rid of that. If it is neither of these, the fuel pressure regulator could be leaking. Other than this, the car would need to be diagnosed by a shop before action is taken. I hope this helps you!

Testimonial: "I ended up taking the car to a local shop for diagnosis. It turns out that the fuel pump is week and not supplying enough pressure to the motor. "

Why my car turns off while driving?


When it doesn't start does it not turn over or does it not fire? When you are driving does it sputter and quit or just suddenly stop running? Does it make a difference what speed you are going? Does it happen after a certain period of time? Does it quit when going over bumps? When it quits will it start right away, or wait a little bit or get it towed home because you don't know when it's going to start again? Do you still have a carburator or throttle body? These questions would help to narrow down what could be causing your problem.

The car runs and then just quits. after about 20 mins it will start up again but it keeps dying and wont stay running. i think it may be a sensor of some sort.

P.1391 problem code car starts but run for 10 to 15 min then cuts out then when u try to start it back up it wont start or u have to keep foot on the gas machine is reading code p.1391


Well I have had this problem with these cars before. Every time I had one of these cars do this it always turned out to be the fuel pump. It would start perfect when it was the first time you started it for the day but when it was warm it would quit after awhile of driving it. Also it did seem to do it more if there was a 1/4 tank or less of gas. Also when i would drive them for a bit and shut it off and let it sit for about 15 mins and go out to restart it it would start super hard and run crappy till i got it going down the road. I think there is some seals in the fuel pump the go bad and start taking in a little air causing the car to get vapor locked. I just know when I had this problem I replaced the fuel pump and never had the problem again. Hope this helps. Don't forget to rate this. Thanks

Suburban stalls while driving after running for 15-30 minutes. After letting it sit for 5-10 min it runs fine for another 5-10 minutes, then starts doing it all over again.


a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,
