Question about 1992 Cadillac DeVille
Could be something in the distributor cap, a blockage in the fuel line, even a bad timing chain.
You need to know if you are getting spark to all of the plugs, fuel pressure to the injectors, and normal compression.
If it is a fuel problem you should be able to spray carb cleaner into the throttle body to make it try to start. If you have spark but at the wrong time, it will backfire by firing on the wrong cylinders. This can be caused by a faulty dist cap or rotor, or the timing chain.

I read somewhere that the fuel pump is lubricated by the Gasoline.It warned to never run out of gas with these Cadillacs.It may need a new fuel filter now.
The junk may have collected in your fuel filter?
Someone posted they had there fuel pump quit after running out of gas 3 weeks later. Try disconnecting your battery for 10 minutes first to see if it is actually the Anti-theft system.

hello. it should be located under your car on a line that's coming off your fuel tank and yes you can do this your self very easy to do ,you'll need a few box/open ended wrenches that's it you'll need to check the fitting or the nut on each side of the filter to see what the sizes are,befor removing the filter you'll want to take off your gas cap and remove your neg battery cable ,not when you find the filter it'll have nut on each side all you have to do it loosen them but make sure that you don't break the fuel line or kink it and after you have both sides loose then just finish turning them off and there you go the filter is off, nope no removing the gas tank some newer models you do and the filter is attached to your fuel pump and don't need replaced but for your car and year you wont need to remove the tank. good luck

your water pump may need to be changed. have a trusted mechanic check it. the water pump is connected to the drivebelt of your 4.9 l engine, and if thats where the sound is coming from you can be pretty certain

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
