Question about 1980 Cadillac Deville

1 Answer

I have a 1981 Cadillac Deville 5.7L Diesel. It was working great until about a week ago. It tries to turn over but it wont start so I know that its not a power problem. Ive tried all I can think of. I just need some outside opinions. Ive already changed the oil, fuel filter, breather elements, and other things. What could it be?

Check the end leads on the ignition switch. You should be able to disconnect the housing around the steering wheel. Remove the ignition switch and check the leads. If you smell or see them burnt, replace the switch. Otherwise you need to take a look the carb. Most times, it has a problem recieving fuel, which causes it to "try" to turn over but doesn't allow it to start.

Engine wont start, BCM just replaced, inflatable restraint and check engine light on.


need to start with do you have any obd code with key turned on
caddy is more complex system than most , check fully charged battery, and not a jump start, and battery is in very good condition .disconnecting battery would only clear codes leaving you with nothing to go on hopes this is some help to you.

My 1981 Cadillac Deville 5.7L Diesel wont start. Ive checked all that I know including starter,battery,alternator,etc. Also, checked fuel pump, feul filter, fuel lines, injection pump. I topped off all of...


What does changing the oil,changing filters etc,have to do with the vehicle not starting?
What actual testing was done on --battery,alt,starter.fuel pump,etc.,how was this testing conducted and what were the results?
No fluids are consumed, in any motor vehicle,
If you have to top off,you have a leak,repair it!!

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

No heat after burnt smell


Either your Fan motor is faulty or the fan control resister assembly is burnt out, either of those will cause the smell.

2001 Cadillac Deville problems starting


I have had the same problem and I have come to the conclusion it is the security system. After 3 minutes the car will start so there is nothing wrong with the battery or starter. I have had it to the dealer a few times and they cannot solve it. It may be the locks on the doors and they may not be resetting properly. I have learned to live with it.
