It would just fail to fire. If it was mine, I'd start putting in some temporary status lights so I could tell how far the starter signal is getting. I'd probably start with one on the starter solenoid terminal and one on the Ignition switch start terminal. Then, next time it happens, you'll get a little bit more info from the lights. It'll be a long job, I'm afraid. Cheers, Colin.
