Initially check:-- fuel pump relay. It may be loose and corroded. clean and re-fix. This will solve the problem in most cases
if still problem exists:- Check the computers for diagnostic CODES via:

1. Ignition ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

On your fuel data display CODES in the form of LETTERS/NUMBERS will appear along with the word HISTORY or CURRENT with each code that displays.

Write them all down EXACTLY as they display and when they stop displaying you will see PCM?


Turn OFF ignition.

I got a 1987 Cadillac sedan Deville and just put a new start on it it will start up and run great but if u turn it off it takes forever to start back plz help


sounds like a problem with the fuel getting overheated and evaperating when turned engine off , check the engine cooling system is pumping through the fuel intake manifold section as a starting point, check that the engine cooling fan runs on after turning engine off as this cools the engine down to stop the fuel evaperating in the fuel lines etc

WHAT IS THE PURPOSE OF THE COOLANT TEMPERATURE SENSOR IN 1997 CADILLAC DEVILLE


the coolant temp sensor lets the cars computer know that the engine has warmed up and to allow the fuel injection to go to what is called "closed loop mode" this is where max fuel econ and low emmisions are available , the driver can know car is not in closed loop mode by the higher idle that cpu adds to allow car to warm up faster
also on cadillacs/buicks only it lets the air condition system go to open vent where it allows fresh outside air to be drawn in to cabin

I wouldnt recommend doing that. Get a wiring diagram of the fuel system and backtrack from the pump. Check fuses and the fuel pump relay for activation first

I jus bought a 96' cadillac deville and when i was driving home the "Servie engine soon " light came on and under the MPH gauge the "service transmission" flashed across the dash ! i also noticed that when...


It sounds like the transmission oil could be low as it doesn’t have to be down much for your type of problem to occur.
To check, the oil should be warm with the engine running and the transmission in Neutral. The level on the dipstick should be between the Low and Full Marks. There is about 1 Pint difference between the marks.

Cadillac 1997 deville passenger side electric window wont go up


If it's like my 1990 cadillac deville, get pliers and pull up on the window while pushing the switch up for the window. There could be a bad motor. How much? I don't know. It will vary from shop to shop.

We all need help sometime.
