Question about 1988 Jeep Comanche
My 88 jeep trucks fuel pump will not turn on the ground is bad some were past were it goes in the cab iam having trouble finding were it goes to see if it is just a bad connection
Try splicing in a new ground and see if that get the fuel pump running. also you can test it by applying 12 volts to the fuel pump wires themselves. if the pump is ok it should spin right up. if the connections are good and the fuel pump still doesn't run, it may be the pump itself that is bad. verify that its a always grounded switched 12 v style pump before attempting to test. if the ground wire just bolts to the frame or the cab then its a normal grounded system. some of the pump are always live and switched by applying a ground.
