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,
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.
Good Luck!
