Question about 1995 Jeep Grand Cherokee
New fuel pump, new fuelpump relay,new throttle position sensor,checked MAP sensor, replaced crankshaft sensor,pickup coil,etc.....
When I try to start the car it won't start right away. I have to turn key on and let it set for a long time before it will start. It will click from the fuel pump relay, when this stops then the relay on the throttle snaps, it will sometimes start after that, when I try to start again if it doesn't start the injectors snap and RPM gage will fluxuate with injectors. After awhile they will stop snapping, because of this I have gas in my oil.
When I first posted, I did not read "comments" after reading what you have done and our results, it seems as though the engine control system "thinks" the engine is running when it is not. I don't believe this is a key switch problem, otherwise if you turned the key to "on" it would flood the engine. Therefore there is a strong possibility that the engine control unit is staying "hot" even when shut down, permitting the pump relay &injectors to receive trigger signals .BUT, I would also take a look at the pressure regulator on the fuel rail. flow through there may be causing the pump to stay on if too much fuel is being bypassed. And, again...did you check codes???
