Possible throttle position sensor sticking and not returning to closed throttle or idle! May cause a crank no start condition really rather common on this vehicle, at least at the shop anyway. SCAN TEST will find the problem!
What is a SCAN TEST
When a mechanic uses a scanner, not a parts person with a code reader, to look at the same thing the computer sees is a scan test. A must have for this kind of repair. You have never heard of this???
