Replaced fuel pump relay, fuel pump, fuel filter, come to find out there was no power going into the fuel pump relay and fuel pump fuses. weird thing is sometimes I will get power because the car start right up. I piggybacked power in the fuse box and the car starts/runs everytime the only problem is the battery drains when im not driving it.

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

99 cadillac deVille ran out of gas now it wont start

Its possible you cooked the pump. The pump needs liquid gasoline to keep it cool and lubed. There's also a chance the pump is damaged from debris from the bottom of the tank.
If you have fuel in the tank, you would jumper the pump relay to find out if the pump is running and what is coming out of the filter under the car.

My windows wont work

Why do we need to know about the fuel pump replacement?

If you checked fuse for the power windows,then you need to
know that they have a circuit breakers, not relays,so now you
need a repair shop or dealer to see if any electronic module
controls the windows.

If your asking about one or two windows & the rest work, then the approach is different

It's a 1991 deville,the fuel pump is not pumping fuel, all fuses are good, sat for awhile, runs if you dump fuel in intake, 30 seconds

Hello, did you check the fuel pump relay also? It is in position H in the fuse box under the panel on the passenger side. Can you hear the fuel pump run when you turn the key on? Fuel filter clean?
Checked fuel pressure at the fuel rail? If the fuel pump is not coming on, need to determine if it has voltage at the connector on the tank. If voltage is present, and ground is good, then the pump is bad. I hope this helps.

Hey i have a cadillac sedan deville 1992 where is the fuel pump located

The fuel pump is located in the fuel tank. On these GM cars, the fuel tank must be dropped in order to change the pump. It is alos recomended that the fuel filter be changed at the same time which is on the frame of the vehicle, left side. the pump at autozone runs about $75 and don't forget the strainer for about $10. The filter runs about$10 also.
