2001 gagt wont start.....fuel problem??????

i have a 2001 grand am gt with the 3.4 liter. it wont start, it has spark,fuel and the starter whirls it as fast as ever. i put a new crank and cam sensor in it and it still wont start. it has plenty of fuel pressure but it is like the injectors wont open. it was runnin fine the day before i noticed it wouldnt start and i mean perfect, could it possibly be the fuel pump or what could it be??

Welcome to AF!!

If you have spark and fuel pressure there are only a couple of items that it could be. A bad Engine Control Module or a broken timing belt. Check the cams to see if they are rotating when you turn the engine over. If not then you will need to have the belt replaced. If the cams are rotating when you turn the engine over then the only thing left is the computer. They usually don't go bad like that but anything is possible.

my car has a timing chain and the cam is rotating, so do u think that the chain could have sliped cause i have been told that the teeth that the chain are around are teflon teeth and they wear and can cause the chain to slip??

nevermind people it was the theftlock system i searched some other threads and found out how to reset it and luckily it freaking worked!!!!!!!!!!!but hey i couldnt have done it at all if the people on this site didnt direct me in any way......so BIG THANX to all you people who take the time to help others out!!!
