let me know if the anti theft light comes on and goes off with the key in the ignition and on. If you have a multi meter or test light we can check for power at the starter. If there is power to the starter you can try to rap it, sometimes the shock will get it to work a few more times. Let me know how many volts at the battery
lets start here
make sure the anti theft light goes out with the ignition key in the on/run position.
Big terminal should have 12 volts at the starter, smaller terminal should have 12 volts when the key is in the start position(turned all the way forward)
you will need an assistant to check this, be careful
