Could be many reasons. Could use more details like does the engine crank but fails to start and run? Do you get nothing when you turn the key to start? Do you only get a "click" when you turn the key to start? Do the gauges power up when you turn the key on? Give us more info.
Check the timing on the Corsica for jumped timing. Most likely the engine is firing at the wrong time causing it not to start.
fuel pump is the first place i would look
MY CORSICA, 1993 3.1 L IS FAMOUS FOR GOING THRU COIL PACKS, I KNOW IT'S BACKWARDS BUT I START WITH THE COIL PACKS AND WORK MY THRU THE TROUBLE SHOOTING STEPS, 9 TIMES OUT OF TEN I HAVE REPLACED THE COIL PACKS. CHEVY LOCATED THEM IN A POOR PLACE. TIM
could be a number of things but most likely is the TPS or fuel injector
If this Pontiac Tempest is the same car as a Chevy Corsica, and it has a v-6, it should be automaticly tightened. If it wont tighten, you might check to see if it has the right belt, If it is the right belt, it could be the automatic belt tensioner.
1990 gmc p/u 5.7 wont idle showing code 12
no the camaro wheels are 5x4.75 and the truck is 5x5. so they wont fit
Check the timing for the 90 Corsica. the most likely cause for the engine not starting is it has jumped time causing the engine to fire at the wrong time.
There are several safety mechanisms for the Chevy Corsica. if you accidently left the car out of park when you turned of the car, in some models if your lights are left on it wont let you take out the key.
I was told it could be bad fuel pump.
You are missing fuel or spark.
if it is cranking but wont start check for spark, fuel, air and compression.
