Neon will not start after being driven on hot days.
You have an intermittent problem in your start circuit. I'm sure you also have some choice phrases to describe it, go ahead and vent, we have all encountered frustrating problems.
The reason shops can't find it is because it isn't happening when they look at it. Anytime a hot engine is shut down a lot of heat is generated in the engine compartment. So opening the hood helps yours cool down faster and start quicker, a good clue. I believe if you had it at a shop when it won't start, they might find it. First thing they would check, or you could if you have a voltmeter or testlight, is if power is reaching the starter from the ignition switch in cranking position. This is the small wire on the starter solenoid. If there is power there when the engine won't crank, quickly reconnect the wire and verify if car will crank or not. If still nothing, it may be a poor ground wire(battery or engine ground) or a poor battery cable, since you know the starter is good. If you reconnect the wire and it suddenly starts working, it may have just been a loose connection on the wire you pulled off. If it keeps happening when your hot engine is shut off, test may have been invalid-intermittent problem has only now come back, so run the same test again.
If you or a tech ever find no power on the solenoid wire in START, that narrows it down to the path from the ignition switch to the starter solenoid. One needs to trace that path, looking for where the power is stopped. A couple of possibilities are the starter relay and the neutral safety switch. You could try a new inexpensive starter relay and see if that solves it. If not, then further testing needs to be done before giving up or throwing some expensive parts in and hoping. But you have narrowed it down which helps. It could be some arcane problem like a ground source for the starter relay, or who knows what. Have the start circuit checked, and it would be easier if the no crank condition is present when checked. Good luck.
