2003 Mercury Grand Marquis no start hot issue, after it's been driven for a while, BUT only when it's really hot outside (80+ degrees), like lately. My dad was driving this car today and after driving for about a hour or so, he went into a store, came out and no start. The car has to cool almost completely before I'll start most of the time and sometimes he has to feather the gas pedal to keep the engine running if he can get it to start. Last year we had the crank sensor replaced with a OEM one, thinking that was the issue and that fixed the problem for about 9 months but now the problem is back. We took it to a Ford dealership and since it wasn't hot outside (it was in the mid 70s) they couldn't duplicate the problem. The did however say, they found a crimped wiring harness back by the trunk, charged my dad $900.00 to fix it and the problem is still there, like I said it just happened to my dad today again, since it's hot as hell outside.
