454 tbi hot start issue
Hoping for some help here. Please. I have a 1987 V30 pickup with 454 TBI.
The truck starts cold just fine and will run and drive all day just fine. The problem is only when the rig is hot. It wont restart due to no fuel from injectors. I have spark when this happens just no injector pulse. If I spray starting fluid into the throttle body, the truck will start and run like normal with no problems till I try to start is hot again. I also have good fuel pressure and oil pressure. The oil pressure sending unit is new, the fuel pump relay is new. Just need some new ideas here. |

How hot is the motor when you turn it off?

The motor is at operating temp. about 180. When I shut it off, it wont restart till it cools down.

I figured this problem out, finally. It wound up being the ground in the ignition switch assembly.
