Question about 1992 Cadillac DeVille

1 Answer

I have a 1992 cadillac deville and two days ago while I was driving the engine stammered then shut off as I was turning at an intersection. It will not start and acts as if it is out of gas. It will also back fire. I had just filled up the tank the night before. I have had the fuel filter, pump as well as the strainer replaced. The car still will not start and will backfire. Can anyone give me any suggestions?

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.

SOURCE: Fuel problem 1998 cadillac deville

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.

Check for a clogged fuel filter. A clog could cause a pump to fail.

SOURCE: 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

Hi! My 1999 Cadillac Deville for about 2 weeks started messaging low refrig-ac-off. Check engine light on!.


When you change your oil is up to you,you set the
months & miles you go. Any car with a reminder
for oil is just a gadget

You were told that your low on a/c refrigerant by the
message

Now the check light related or not has to be addressed,
by checking for codes & diagnosing the effected system

Your a/c system needs repair,not added to, only to leak out
& polute the atmosphere

1992 Cadillac Deville ideals really slow and miss's when I step on the throttle


Do this frist and then if the miss is still there have the spark plugs and plug wires replaced.

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

My 1990 Cadillac Deville wont start or engage starter


Sounds like you blew fuse. Fix fuse and borrow a car starting switch they use at car repair shops. As long as you can turn tumbler to on ,you can start using the starting switch from repair shop..There should be a way to run a start button to start car and your off/on key should be OK

I just bought a 99 cadillac deville about two weeks ago from a dealership. It's been driving like a dream since I got it, but it turned off on me suddenly yesterday. It actually turned off on me three...


Its possible that the ignition control module may be faulty,or the crankshaft position sensor.I would suggest that you try to replace the crankshaft sensor first.The crankshaft sensor is located in the front of the engine near the ac compressor.The ignition control module is located on the back of the engine mounted above the rear valve cover underneath the coil packs.

My 99 cadillac deville ran hot about 8 months ago i took it to the dealer thay told me that i need a new engine and to drive it for a couple days and see what happen i have been driving it for eight months...


If you have no obvious external coolant leaks then the most likely culprits would be leaking head gaskets or warped heads. I would take the car to an engine rebuilding shop and get a second opinion to the dealer, not to say that they are wrong, but your engine may be salvageable at a cheaper cost and those guys would be better positioned to tell you that. Hope this helps.
