Starts and dies

[pawhiteboy]

Rebuilt the motor. Fied itover in the garage and idled just fine for about 7 minutes. With it still running at idle, I picked up the rear bumper and pushed it out of the garage and into the driveway. It then started to bog down and died. It would not start again.

It only fired over when I held the throttle wide open, ran for about 20 seconds and died again. It would now start for about two seconds and die. Then it would start and die immediately. Seems fuel related. TPS possibly?

Crank positon sensors and TPS were not adjusted or removed during rebuild.

Did the injectors get seated and plugged in correctly? I rebuilt a motor and had that issue with the results you described. Otherwise double check your ground (wire on the triangle support), ECM connections, fuel pump connections and everything on the wire harness.

No start condition when I got to it today. Manually primed fuel pump and fired right over. Ran until it lost its prime again
