Car won`t start when reaching operating temp.

I have a`94 Buick LeSabre Limited with a 3800 engine.
When the engine`s cold,it starts fine and drives fine.
When it reaches operating temp,if you shut it off
It will crank but not start back up untill it`s cold again.
I`ve replaced the crank and cam sensors but no change.


  • The problem might be with an ignition module that's sensative to heat. Have you tested for spark when the engine doesn't start?

  • haven't checked that yet
