Question about 1997 Oldsmobile Cutlass Supreme

1 Answer

How do you check a dis coil (three coils on Ignition Control Unit) from 1997 Olds Cutlass Supreme 3.1L engine. Might you have the specs? I have a good ohm meter. Hand held OBD unit reports multiple random cylinder misfirings. Might it be fuel injector problem? I figure probable electronic problem. I can get the ICU checked at the parts store or should I just go to a garage with a good diagnostic unit?

3.1L Engine

  1. Tag and disconnect the two plug wires attached to the suspected coil.
  2. Remove the two screws securing the ignition coil to the Ignition Control Module (ICM).
  3. Remove the ignition coil.
  4. Before testing, visually inspect the coil for carbon paths or cracks which will contribute to weak spark symptoms.
  5. Using an ohmmeter, check the resistance between the primary terminals on the underside of the coil. The resistance should be 0.50-0.90 ohms.
  6. Check the resistance between the secondary terminals. It should be 5,000-8,000 ohms.
  7. If the coil failed either test, it must be replaced.

I have a 91 olds supreme 3.1 v6 it shut off and won't start back .... It starts but won't turn over.... And when turn the key back off it's blows the dis fuse wich mean direct ignition system...

Check the coils that have been replace for bent or broken prongs that plug into the ignition control module and if nothing looks damaged then i would think the ignition control module is faulty.Replace ignition control module.

Hi I have a 1991 Olds Cutlass Supreme, with a 3.1 liter engine. My problem is when the car warms at stops it runs rough. Sometimes shuts off. Sometimes when crusing at speeds 30-50 the car sort of jerks...

My 3.4 liter 91 Cutlass Supreme has similar problem when warm the engine misses (car jerks). But its fine at idle and without any accelerator pressure. The SERVICE ENGINE light also comes on intermittantly. I am going to test the ignition coils.

It cranking than dying out

The Olds engine (I assume it is a 3.1) has a module under neath the coil pack. These modules can be a real problem as well at the coil pac. Most Autozone and Advance parts store can test the module for you if you remove it from the car. You will also want to test the fuel pressure. The specs are in section four of a Haynes manual. again at the parts store.

hope this helped.

My 1997 Olds Cutlass Supreme won't turn over

Better have the starter, battery and chargeing system all tested. A starter can cause the problem.

'93 olds Cutlass Supreme eng died now not firing.

Its not the packs, I am pretty sure that is the distributor in the engine, (the one the coil pack hooks up to) I thought I knew my stuff until a 15 year old neighbor kid came and fixed my sundance that way, that or its a loose battery wire. hope this helps, have a nice day, and drive that thing like it was meant to be driven!
