Verify that both battery terminals are clean and tight. Disconnect any after market systems attached to the battery terminals.

Put the ignition key to ON, Engine not started. Note the battery voltage on the instrument panel. Turn the key to start, while watching the battery voltage meter. If the needle does not deflect, then investigate the starting circuit, ie clutch switch, VATS, TDS.

If the volt meter does deflect, it means that the starter solenoid is energizing but the solenoid contacts are not passing current to the starter motor. Rebuild the starter solenoid or replace the starter.

NOTE, keep this procedure handy because it has to be done when the car won't crank. For an intermittent problem like you stated, you will have to wait until the next failure.

Good luck,

Jim
