Question about 1990 Cadillac Deville

My 1990 Cadillac Deville just cut off

As I was leaving the gym my 1990 Cadillac Deville just cut off and I tried to crank it but the starter would not engage and the lights on the inside would not dim like they would when I would start it. I then changed the starter and still nothing! I got a new battery and switched the car on and hooked a wire straight from the battery to the starter and the engine just turned over and would not start.

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 1990 Cadillac sedan deville cranks and run for bout 5 sec then it cuts off it tries to crank but it wont catch.


Check the condition of the following:

1) Spark plugs
2) Spark plug leads
3) Air filter
4) Fuel filter
5) Coil(s)

If they all check out, then also check the operation and delivery of the fuel pump.

My 1990 cadillac deville want start with key. So I had to run a wire to my starter with a targa switch to crank it. So what do u think I can do to fix it?


Clean the key off so the resistor on the key will register with the security system.

If this doesn't work, maybe take it to the dealer and have them check your key out.

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.

Chevy malibu won't crank dashboard functions no theft system issue, turn to on position and makes no sound...could this be the starter?


Most definitely sounds like a starter. Try toggling the key to the start position several times a second until the starter operates. I do this to my 1997 Cadillac Deville occasionally as the weather changes without changing the starter (which probably should be done).

I also have a 1990 Cadillac Deville that does this occasionally.

Must be a GM thing.lol.
