    Where do you have the relay checked for operation?

    If it is not the relay what else could cause the pump not to work?

It is located in the engine compartment, passenger side, side of inner fender on a bracket. I believe it has 5 pins and is about a 2" cube in size. Autozone can't test it, but a new one is $10 there and an easy install. Check the bypass plug at the relay by attaching a 12v power source (a short wire from the + terminal of battery) and listen if your fuel pump comes on, then you will know if it is the relay. Just had similar problem with my 89.

Check you owners manual for sure but it should be on one of the fuse panels in your engine compartment. If the fuse panel is not labeled then the owners manual will tell you which one is the fuel relay. The relay will be about a 1" by 1" square black plastic piece.

Cant find the fuel pump relay on a 1989 chevy caprise

The fuel pump relay is in the engine compartment, attached to a bracket on the side of the right fender. It is approx. 2x2" black cube and has a plug attached to it. You can test it by attaching a short wire to the red test wire (coming from this plug) and touch this to your 12v positive terminal on your battery. A replacement relay is about $10 at auto parts stores.

I need to find a fuel pump relay on a 1989 chevy caprice

The relay for a 305 V8 is under the hood on the passenger side fender. It is a black 2" cube hooked onto a bracket. There is a red test wire and clip coming from it. You can bypass the relay by attaching a short wire from the clip to the positive terminal on the battery. Have some one kneel by the gas tank while you test the relay. If it comes on (the pump in the tank will buzz) then the relay is bad. A new one is $10 at the parts store. Just swap it out.
