Cadillac is fond of multiple relays / sensors - although first I would suspect the crank shaft sensor, next I would test the Mass Air Flow sensor and Idle Air Control motor, Getting it scanned would be recommended, as you could throw a lot of parts at it and not cure the problem. It could also be a corroded connector for one of the above mentioned sensors - or a sensor I didn't list!
Hope this helps and thanks for using Fixya!

Try to reset the p.c. by unpluging the batt. for 10 min that should do the trick.

SOURCE: 1999 cadillac deville air wont work

There's a blower motor (fan) under the hood and up against the firewall near the center of the car that takes some work to remove. It has gone out in the last 2 of my 4 Cadillacs. Turns out if you're not real careful with the positioning of the spark plug wires they will brush up against it, and if one of them gets cracked or brittle it will "arc" and short out the blower motor. The a/c compressor should still come on (you'll hear a click when it engages) but you won't get any air blowing into the cabin, hot or cold.

The part was like $200 stock (year 2000 prices) and it took about an hour to remove it. My Caddy at that time had this damn strut bar going across the engine bay which we eventually removed to get to the blower motor.

More likely it is the spark plugs and the engine is mis-firing... take them out and check them

My 2003 cadillac deville dts drags when i try to crank it, I replaced the battery and starter, and it still wont crank.

Hi Able:
"Crank" to me means turn over.
"Fire" means actually try to run.
If it won't crank and you have a new battery and starter, I'd be checking the terminal connections, wires, cround connection, and solenoid. If all of those are good then we need to start checking the engine condition. Recently running or sitting for 5 years and full of rust?

My 2000 cadillac deville just shuts off periodically an fires right bk up sometimes then sometimes it wont can anyone tell me wat this could be

When it won't start right back up , check an see what's missing ! Spark - pull a plug wire an hold it close to something metal better yet put a screw driver in the plug wire end an hold close to a metal part of the engine an have someone crank over the engine ! Then if there is spark ,spray some stating fluid into the throttle plate . if it tries to start you have a fuel problem . If there is no spark could have a bad ignition control module , or coil or the crankshaft position sensor may be going bad ! Does your caddy have a tachometer ? See if it moves while cranking , if not bad crank sensor !

Where is the crankshaft position sensor located on a 1994 Cadillac Sedan Deville 4.9L V8? I need a diagram or illustration or something. Thanks.

Your 4.9 has a distributor, correct? If so, it does not have a crank sensor, per se, it has a hall effect sensor in the base of the distributor, also called a coil pickup, just below the rotor. It has a harness that goes through the distributer housing.cap and plugs into a harness, and is pretty easy to replace.
