TO test the fuel pump relay on a 1989 Pontiac Trans am a spark tester can be used. Connect the tester to a ground on the vehicle is check the voltage to see if it is receiving the proper current.
For the fuel gauge? In the gas tank on the fuel pump.
The fuel pump relay is located on the driver side, under dash mounted behind kick panel. Fuel pump is mounted on top and inside the fuel tank.
FOR TESTING PURPOSES ONLY you can jump the fuel pump relay to operate the fuel pump. If the pump is not running, knowing GM fuel pumps, it is probably a faulty fuel pump.
A 2005 PT Cruiser does have a fuel pump relay. They have a fuel pump relay rather than a fuel pump switch. The fuel pump relay is located in the fuse box.
For testing purposes only you can jump the fuel pump relay (#30 and #87).
The main relay and the fuel pump relay are the same. Take the fuel pump relay and swap it with the main relay and see if that will help you....
If the relay is bad, then the fuel pump will not work.
Yes, it is a fuel pump relay.
There are testing procedures for relays and ohm readings but it differs for all makes. The easiest way is to swap out an identical relay on the vehicle and check to see if the pump comes on. I know that on Ford Rangers there are 3 that are the same ECC, fuel pump, and AC. Since I knew that the ac worked I moved the relay over to the fuel pump and got no response still, so I moved it over to the ECC and both it and the fuel pump worked so that told me that the ecc relay was bad and it in turn triggered the fuel pump relay to activate in series.
Bypass the relay and if the pump works the relay is bad.
Bad relay, No power to relay, Wiring from relay to pump and our most likely problem is, the fuel pump is bad. changed it already
The fuel pump relay switch looks like the normal electric switch. The function of fuel pump relay switch is turn the fuel pump on.
