Question about 2001 Cadillac DeVille
Car won't start, turn key and nothing. Battery is good. Have tried locking and unlocking with remote on both keys. I would guess security system has locked up.

I had a similar problem intermittent NO START. No click, buzz or other noise. Everything worked but wouldn't start. Unfortunately it took two trips to the dealer to locate the problem. Next time it happens find the purple wire in the wire harness under the cover on top of the engine. A simple tester that connects to ground with an lighted "awl" type probe will tell you if there is power from the key to that point. If there is and you're not starting then the only other thing downline is the starter. Can't repair them only replace. Dealer will be about 900.00 P&L , If you're daring or have some help it's right on top DIY 400.00.
