No power to fuel pump on '93 Grand Cherokee Limited
I have a '93 Grand Cherokee Limited that my daughter drives. I have no power to the fuel pump. I have power to the relay & have replaced the relay. I have also manually reset the security system (no remotes). Any ideas?
Do you have grounds at the relay? if not it could be the signal from the pcm that isn't working. also check your fuses. an efi fuse could keep the pcm from sending the signal to the relay. also check the wire from the relay to the pump for high resistance. you want continuity between the fuelpump and the relay power wire.
