There isn't any time/mileage interval, if a tower where the plug wire attaches is corroded it is time to replace, if that's the case then that plug wire needs replacing also

Does a 1997 Cadillac Deville have a coil pack or a distributor cap


Michelle,

The 1997 V8 engine in the car is fitted with coil packs which are quite visible on the top of the engine. These need to be replaced when they eventually fail as is common.
Here is a video on the coils which may help you.................

1996 cadillac deville I by passed heater coil but water is coming from somewhere else and is running on floor it's not heater coil and what ever it is its draining my radiator so car over heated


To by pass the heater coil, you must connect the two hoses going into the heater coil. Did you do this? or did you just plug one hose line? best to replace heater coil if it is leaking to get heat working in winter.

My 1995 cadillac deville feels like it misfires or stalls while driving. It had a p041 code. Replaced ignition control module and still the same problem. Anyone have any suggestions?


The P041 code on your year model Deville is distributor related...either the hall effect switch and/or the magnetic pickup coil is defective...my guess would be the pickup coil. If your car has high mileage, you might want to consider replacing the entire distributor with a rebuilt one. Good luck, i hope this helps,

While cranking loud backfire than i restart engine again than it cranks than starts up,this happend about 6 times during 3 months. Car did same thing yesterday, but it just cranks won't start 98 olds...


Not sure if you have a 1996 Cadillac Seville or a 1998 Olds Aurora but I would check the Ignition Coil Packs. One or more of them may need to be replaced. Also if you were working on the car and got the wires plugged onto the wrong coils then the firing order sequence would not be correct and this can cause a misfire or backfire conditon.

Ignition wires cannot rest near the primary wire harness of the ignition module, which can cause electrical interference and a no start condition or a misfire condition

On my friends 1997 Cadillac Seville it was easy to replace all 4 coil packs took less than 30 minutes and made the car run much better. Just make sure to get the firing order right. If necessary find a diagram of the correct firing order for you vehicle.

A good place for mail order auto parts is rockauto.com

I have pasted a picture below of what an ignition coil pack looks like

How to change a starter in a 1990 cadillac sedan deville?


First, I would determine it is bad. I have a 1990 Cadillac Sedan Deville, and sometimes it doesn't turn over. But, if I toggle the switch a few times or up to 5 times, it starts to turn over and the car starts.

I have the same problem with a 1997 Cadillac Deville.

If you are set on changing it, here is a picture and instructions on how to test:
prev.gif next.gif Starter TESTING Voltage Drop Test Fig. 1: Schematic of a voltage drop test 91052g10.jpg
NOTE: The battery must be in good condition and fully charged prior to performing this test.
  1. Disable the ignition system by unplugging the coil pack. Verify that the vehicle will not start.
  2. Connect a voltmeter between the positive terminal of the battery and the starter B+ circuit.
  3. Turn the ignition key to the START position and note the voltage on the meter.
  4. If voltage reads 0.5 volts or more, there is high resistance in the starter cables or the cable ground, repair as necessary. If the voltage reading is ok proceed to the next step.
  5. Connect a voltmeter between the positive terminal of the battery and the starter M circuit.
  6. Turn the ignition key to the START position and note the voltage on the meter.
  7. If voltage reads 0.5 volts or more, there is high resistance in the starter. Repair or replace the starter as necessary. NOTE: Many automotive parts stores have starter bench testers available for use by customers. A starter bench test is the most definitive way to determine the condition of your starter.
---
Remember to disconnect the battery and remove the wires from the starter at the hex nut.

Then, remove the 3 or so bolts that hold the starter on using an extension and ratchet if necessary.

Hope this helps.

I'm having the same problem, in research I have been told I need a new ignithion switch and or key. Ignition switch is not an easy thing to replace, The air bag must be disabled and that is a proccess discribed in another Solve, you should look further on this sight for that information. I'm just nursing mine alone for now.
