The fuel pump relay is located behind of the glove box. The fuel pump fuse is located in the same box (Relay Center). The fuel pump relay is either the 2nd or 3rd one down in the 2nd row. You may want to check your computer codes and make sure it is not your ECM or BCM as they can shut down ones fuel pump too.

I am not a Cady expert. In my experience, you can probably run an engine with out the air pump ... but why would you? The air pump reduces emmissions and improves performance. Removing the pump will also require reconfiguring the belt scheme.
Hello, The fuel pump is inside the gas tank. Remove the exhaust, Disconnect and remove all hoses and lines, also disconnect all electrical wires, remove 4 bolts from straps holding tank. Drop tank down. Remove lines and hoses from top of fuel pump module, remove lock ring, pull fuel pump module, turn unit as necessary so you don't destroy the fuel level sender. Hope this helps
first, the 1993 cadillac deville should have a throttle body not a carburetor. And, I think it has ported fuel injection to each cylinder with a fuel injector for each cylinder if it's like my 1990 Cadillac Deville.
the fuel pump is inside the tank. did the distributor cap get wet when you were installing the thermostat? check to see if the wires are pluged into the distributor cap well. if you use a fuel pressure gage you will be able to determine if the fuel pump is working.
