SOURCE: replace my fuel pump relay
The fewl pump relay is located in the bottom part of the fuse box under the hood. It is labeled on the cover where it is. It is one of the big black square s usually taped to the one above it. Cost is about fifteen bucks at advance auto.

Unfortunetly Cadillac does not have an access panel for fuel pump access until the newer years. You will need to drop the tank. Also, don't let the tank come slamming to the ground, make sure you take it slow so you dont dammage the lines to the sending unit.

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

hello. it should be located under your car on a line that's coming off your fuel tank and yes you can do this your self very easy to do ,you'll need a few box/open ended wrenches that's it you'll need to check the fitting or the nut on each side of the filter to see what the sizes are,befor removing the filter you'll want to take off your gas cap and remove your neg battery cable ,not when you find the filter it'll have nut on each side all you have to do it loosen them but make sure that you don't break the fuel line or kink it and after you have both sides loose then just finish turning them off and there you go the filter is off, nope no removing the gas tank some newer models you do and the filter is attached to your fuel pump and don't need replaced but for your car and year you wont need to remove the tank. good luck
