1993 Grand Cherokee 5.2 not getting power to fuel pump
My 1993 5.2 Grand Cherokee is not getting power to fuel pump. I have replaced fuel pump,
camshaft position sensor, ignition coil, fuel pump relay. I am at a loss. I primed the carb
with gas and it started and ran until I turned it off. and then I turned the key to see if the
fuel pump would prime and it doesn't prime. Has to be a electrical current problem. Could
it be the PCM?
check all other fuses and relays, especially the pcm relay. inspect the wiring to the pump. get a tester and trace the wires. check for 12 volts at wiring harness to the pump.
Where is the pcm relay located?
Not sure on your model, but it shouldn't bre too hard to find. Is there a power panel under the hood? Possibly in the glove box? Also, it wouldn't be a bad idea to scan the computer for codes whether or not you have a check engine light or not. If there is no power to something, check every fuse you can find.
