Sounds like a bad motor, or if the motor is capacitor start, the capacitor could be bad. Does the compressor turn freely? (disconnected from the motor)...if not, that's the problem. If so, check the capacitor.

Have you posted this question in the tools forum?

If your compressor pumps up from 0 psi and shuts off at full pressure and won't start when there is tank pressure check the tank checkvalve. Many compressors won't start if there is pressure on the compressor head.
