On the 86 5.0 i just picked up, like the title says, the car with fire right up first turn of the key. But once it warms up to normal operating temp and the car is shut off it will not start until i let it sit for bout an hour. Anybody had this problem or know what wrong?
I think the starter is old, check to see I the car has aftermarket headers, they might cause the starter to get hot so when you try to start the car again it won't be able to turn because it locked up, just my 2 cents it happened to me.
ya henry i can start it, drive around fine and idles just fine. But like i said if it reaches normal operating temp it wont fire back up. But if its cold and i start it and shut it off right away it will start right up again. Only does this after the engine is hot?
even tho its turning over ok and trying to start but wont?
If it's turning over just the same hot as it is cold but it just won't fire, then it's not a starter issue. These cars do have problems killing starters with heat especially if you have longtubes, but the classic symptoms of a starter dying from the heat is slow cranking.
Fogged306, how do i test to see if it is vapor lock?
I have no idea how to actually test for vapor lock. I just had a friends car do something very similar. Only his would run like crap when it got hot and if you shut it off, it wouldn't start until it cooled. We noticed that the fuel lines were really close to the headers, so we moved them away from them just to see if that was the problem, and just like that, the car never had that issue again.
I just meant to check and see if the fuel lines were close to the headers.
