so for the last few weeks my car hasnt been wanting to start , it will start sometimes but othertimes ill be stuck in a parking lot for 1 hour to almost 3 hours i dont really know anything about the car since ive only had it for a few months ,everything seems to be stock besides the radio fan and exhaust.

 

Does it crank or not. If it cranks & does not start, look to see if the injectors are spraying, see if you have spark, & if you don't see injectors spraying you'll have to get a noid light & a fuel pressure tester.
If it doesn't crank, check for power at the starter & check the battery connections & grounds.

 

I got it to work i clean the tbi up a little bit and its fine now, thanks for the help!
