We have replaced the ignition module(once) and the crankshaft sensor (twice). We are still having the same issues, stalling/ not restarting and no dummy lights to show what's wrong. We took it to GM to have it fixed but they tell me nothing is wrong with the car!!!!! I know there is something wrong with the car and its not safe to drive my toddler around in!!
How do you know if its the mass air control sensor?! on 2007 Pontiac Grand Prix

Learn how to test ignition system for spark!! Keep provisions in car to do this test!! Next time it stalls and will NOT restart, check for spark!! IF spark is present, then start looking at fuel related components!!.... That's the way it's done, or have a repair shop do this but it will take awhile..... In any event.. Stop wasting your money by throwing on parts!.. Obviously that ain't working!!!!
