Question about 1996 Cadillac DeVille
I have power to the relay and it cycles on and off, but my fuel pump does not run. Is there an emergency shut off switch to be reset?

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

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.

I had same problem in my 90 deville. Drove myself crazy, I replaced the sending unit in the tank with a new fuel pump. I also had to replace the fuel pressure regulator, which sits behind the rail system. It worked for me.
