I tried starting my car not too long ago, put the key in the ignition, was full on gas, all lights worked, both inside and outside the car- the battery was fine and well when i tried to start the car the dials wouldent go up to were they should be and the car, and the ignition was turning but the car was not starting, it would make noise when i pushed the key but it just would not start, and earlier that day it was driving fine, could anyone help me?

hummmmm....

Does the CHECK ENGINE light come on when you turn the key over?

If it does not, then the CrankShaft Position Sensor (CPS) is most likely the culprit, it could be a bad PCM but the CPS is a known cause of this problem.
