My 2003 Cadillac DeVille it will crank but wont stay running what could be the problem and it shakes a little bit

It may be the throttle position sensor (TPS). It is located where the intake air (from air filter) attaches to the intake manifold. The TPS connector should have 3 wires. The TPS controls the air/fuel mixture.

Cadillac wont start

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!

The sensor itself is located under the car right behind the oil filter. It is connected on top of the motor right by the fire wall. You will need an E8 torx socket to get it out but it's a very easy replacement.

How to install crank sensor on 02 cadillac deville

should be located near or behind the bottom engine pulley on the front of the motor, unplug the sensor, unscrew its mounting screw and fit the new one, you may have to get the pulley removed with the help of a friend with a breaker-bar and puller with the car in gear if manual, or use a garage as it will be hellish tight. Don't lose the little woodruff key that locates in the shaft and ensures the pulley does not slip in operation.
