It could be the throttle position sensor, mass air flow or map sensor, weak fuel injector, bad spark plugs, or a number of other issues. If the check engine light is on, getting it pulled may further direct you. Goodluck.

My 1993 cadillac deville is not getting any fuel in the fuel injection what can be wrong car will not start.


I dont know what you have and havent checked, but I would start with the fuel filter. If that doesnt help, check the pump. Turn your key to the on position without starting the engine and have someone crowch by the gas tank and listen to see if they hear the pump kick on. If they dont hear anything, its probably bad. Im just speculating you mean you are not getting fuel up to the injection system and you havent checked these things yet. Sorry if im misunderstanding. Hope this helps, Clay

Fuel filter replacement 1993 Cadillac Deville


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

If you had a strong stream of gas shooting out then you may have an fuel injector problem. Possibly a clogged injector or bad injector.If the stream of gas was weak replace fuel filter first and test again.If problem persists check pump fuse then replace pump. sorry for miss reading your post.
