1993 Jimmy Fuel Pump Relay Location

There are two relays mounted on the drivers side firewall, the existing ones have no numbers. Which is the Fuel pump relay? What is the other one. The parts dealer, owner's manual, and repair manual don't give me this information. Thanks

Well an easy way to find out is pull one relay out and turn your key without cranking the engine, just so you can listen for the fuel pump to turn on.

If you hear the pump, that's not the one, put the relay back in and pull out the other one and try the same test.

One of the 2 will not allow the pump to operate, thus, it is the fuel pump relay. The pump does not receive voltage if the relay is pulled out.

Nice post, good simple way to test.

Does it run. If so, start it up, and pull the relay that is on the left hand side, when you are facing it from the front of the engine. Sorry, I don't know what the other one is.
