ok i posted awhile ago that i had a grand am (93) that would not start.
well, i changed the crank sensor the first time and it popped but did not start, i changed it a second time and it ran perfect for about 20sec. i dont just want to keep replacing them, and gain 20sec of driving time each time. when it runs it will run perfect but then just cut out, no stumbling or anything.
what do you think could be the problem?
i got this car for $500 and its in perfect condition, if i could just find out what the hell is wrong with it, it will be a great car.
HELP ME PLEASE

BTW: it has the 3.3L engine

Well Sn, i maybe can help you. I am not sure what you know but lets try this. When the car stall and wont start again, does it have spark? answer this and i will walk you through the rest.
