Over the past month my 96 Hyundai Accent Auto is refusing to re start after i have driven it even a short distance in hot weather. The car runs great from cold and shows no sign of overheating whilst driving. If i have to fill up petrol or stop and shut off engine it will crank but wont spark to life !. I sometimes have to wait for 1-2 hours until engine is completely cool then it will start , any answers ??.

 

The first thing I'd try to do is start removing relays, checking to make sure they're not corroded, and reseat them back in. It could be as simple as a relay that has worked itself loose from the heat/cold cycles. Fuses too.
