Won't start once up to temp. Starts up right away when cold. Runs smoothly, doesn't hesitate while driving. Just won't start until its cooled down. Any thoughts would help. Thankd

I dont know what side of won't start you are on like it is dead no power to ignition, have lights but won't turn over or turns over but won't start? So...something may not be plugged in or hose is cracked/broke,vaccum leak..fuel filter is clogged, fuel pump is dying? when you get in next time turn the ignition on but don't start listen for a humming noise from the rear then click under the hood and pump should turn off.. the filter is full and you have pressure..

 

I would go for the thermosensors first, one goes to the thermostat housing and there is a wire that goes there and gets bolted down too...

 

Next would be ignition timing...

 

Are you a new owner? Did you do any maintainace? Change timing belts? Thermostat? Wiring? Starter? Could be the starter is getting hot... ignotion switch is breaking down.. try turning a little harder,check fuses, as well the fusible links under the hood on the coolant resivor... I'm sure there's more to look at.. let us know how it goes. Last but not least.. sounds stupid but it happened to me.. my battery terminals gave me problems like that, If they are smashed and trashed they are.not.making positive contact so check those out too..

Just so you know, the duplicate of this post has a lot more Q and A on it.

Yeah just seen that... bummer ;( oh well..

Sorry about the double post
