1990 Chevrolet Truck Repair Question
1990 Chevy Lumina Euro 189Kmi. 3.1litre No Voltage Fuel Pump
Any help would be appreciated as I don't have much hair left anymore lol...Thanks
If the fuel pump relay closes for a few seconds when you turn the igniion switch to the on position and then opens again then you know that everything is good from under the dash and hood as far as fuses and relays.
The problem is probably betwen the relay and pump.
The repar manual for that vehicle should have a troubleshooting section under the fuel section that deals with jumping the fuel pump to see if it works.
On the 90-95 lumina apv,transports, silhoettes, you have to disconnect the electrical connetors under the car that go to the fuel pump by te tank. Disconnetth wire harness that comes out of the tank and goes into connects to frame. Connect 12 bolts battery voltage to the gray wire terminal and the black wire to ground. Make sure battery has a good charge. If the pump runs its ok then check all connections and wiring again. If it doesnt run it may need replacing. You have to drop the whole tank.
Make sure you continue to check your voltage on the hot wires.Let me know how you make out.
