Ok, number 1: disconnect the battery. 2. drop the fuel tank, by removing the retaining straps holding it up(2) note: make sure you have a jack or somone to help, also the lower the fuel level the better. 3. remove the ring on the top of the fuel pump, you'll have to tap it around until it clears all the locks. 4. pull the old assembly out. 5. make sure all the washers and rubber goes bck in exactly as it came out. remove the old fuel pump, replace it with the new on. Also change your strainer, and fuel filter( rear driver side directly in front of the rear tire. drop the new assembly back in, tighten the ring, place the fuel tank into place, put the straps back on, hook up the battery and get back on the road. Note. once the new pump is in place and all electrical is hooked up, before you put the tank back up, have someone turn the ignition, not start it but just cut the car on. make sure you can hear the pump cut on once the ignition is turned on. if this checks out. go ahead and put everything back. I replaced mines with a turbine pump and it works alot better than stock. - Wcb56

drop the fuel tank, it is on top. But before you do that, make sure your fuel pressure regulator is not the problem, probably is.

If you know how to work on cars, about 15-20 min. tops. Disconnect the lines, take out the two bolts that hold on the pump, clean off where the fuel pump bolts to the block, install new gasket and pump and lines. Start up and check for leaks. Done

Try switching out the relay for the fuel pump. the pump seems ok but its not getting voltage while plugged in. If its not the relay it might be the fuel pump fuse. It could be something else in the circuit

No it does not. The only engine in the 1988 Cadillac De Ville was the 4.5 Digital fuel injected engine. The 4.5 engine is a 2 valve per cylinder overhead valve (not overhead cam) engine. It was a good engine but not in the power category as the Northstar.
