Question about 1991 Cadillac DeVille

1991 Cadillac DeVille: starts sometimes;doesn't sometimes

We have had the car tested. The ignition switch has been replaced. Nothing comes up bad. The battery is new. We can drive it for days with no problems. Or let it sit and it starts up. Suddenly, it won't do anything. You'd think the battery was dead. Sometimes you can wait a few minutes and it'll start but lately that isn't even working. Can anyone help? Someone told me it could be the main chip (brain) but we hate to put any more unnecessary money into it.

    The car has been put on the computer and doesn't show a starter problem. We will check the starter/solenoid and the connection on the body ground. Thanks to both of you. We'll keep you informed.

    Have you taken off the starter and had it tested?

    Sometimes the solenoid will give symptoms just like you describe.

Yes, please check the battery posts, that the starter is getting 12V on start, and for a deteriorated ground (or power) wire.

The ignition switch attached to the column is probally bad, check the small wire to the sloenoid for battery when the key is turned to the start postion, if no battery, your not getting power from the ignition switch to the starter solenoid.

2001 Cadillac sedan deVille Frequently will not start on first try. Wait several minutes then starts. Sometimes starts after changing from Key fob 1 to key fob 2


I fought with this issue on my wife's car for almost a year, thinking, ignition, security, starter, changing fobs, etc. I finally caved and replaced the starter - that was it.

When this happens and you turn on the ignition, do the gauges come on,etc? This will help eliminate the ignition switch/circuits as a possible cause.
