Question about 2003 Chevrolet Impala
This had happened twice, it will not turn over/it will not do anything/eventually it does start and there are no other problems
The problem is the factory installed Passlock system. At times for some unknown reason it senses an intrusion even if there is not one and locks down the injectors. I disabled the system permanently about 10 months ago and have never had the problem since. Underneath the steering column there is a metal plate the needs to come out to access the steering column. You may or may not have to remove parts of the dash to take off the plate under the column (held in place by a few bolts. Coming up the steering column is a set of (3) wires Yellow + Black - and white (neutral). These will all be bundled or tied together but they are the only group configured as such. START the car and while the car is running (vitally vitally important!) snip the yellow wire ONLY and tape the ends off. Put everything back together and you are good to go. The yellow or orange security dash light WILL stay permanently illuminated but that will not cause any problems. Life is so much better when your car starts every time.

I Will Scrap This Useless Buick Before I Spend 500.00 On A Key Switch. I Can Buy A Running Ford For That Amount. As You Can Tell I Don't Put Much Faith Or Money In GM Products.

I had a similar problem with my 2003 Impala. My wife called me to let me know that the Impala wouldn't start for her; it didn't make a sound when she tried to start it. By the time I got home about 20 minutes later, it started and was OK for a month or so. The next time it happened we took it to an automotive repair shop and they said they couldn't find anything wrong and it needed to be taken to a Chevrolet Dealer because it was probably a key problem. The Dealer replaced the key cylinder ($500) in the dash and it has worked fine ever since.
