Any ideas- Need help
O.K. Had a great day at Carlisle ( hot! ) and car ran like a champ. Headed back to N.Y. in the afternoon with no issues. Stopped at DQ for an ice cream in Sellingsgrove. While at the window car was iddeling just fine and then just shut off. No noise, bang or chugging, just like it was turned off. Tried to restart, spun over fine but would not light up. Wound up getting towed to the Chev dealer in Sellingsgrove, left the car because it was 4:30 and service dept was closed. Rented a car and drove the other 2 1/2 hrs. home. Any ideas? I checked the obvious. My biggest worry is the Chev dealers abilities to fix it. Doesn't look like a state of the art dealership and feeling like I'm about to get hosed royal being out of state and over a barrel. Car has 28,000 miles, no winters, rain, babied all it's life. It's an 04 LeMans edition. Thank's for your ideas in advance. Be safe.

Forgot to mention that when checking codes every code under the sun was displayed! Not one group with no codes except radio. Didn't have enough paper to write them all down! Very strang indeed. Never an issue with any code or trouble in 16 years. Perhaps my luck has finally run out.

Everyone has an opinion so mine is this, call the dealer and request they only check battery and if that is not the issue have them not do anything else. You rent a trailer or call a rollback and bring the car home to your garage. Towing cost not cheap but neither is a dealer that is just going to see you as an blank check. Good luck.

You posted that every module had a trouble code, except the radio, that tells me that you probably have a serial data highway problem, where none of the modules are communicating with each other, the problem could be as simple as bad connections on the connectors located in the accordion covers at the doors. Hope this helps.

Still kinda sound like the battery is just not injected right or failed possibly a crank position sensor like stated ...
Do or did you hear the fuel pump turn on to say the least after it stalled ?

The rubber accordion between the door and the body of the car contains the wiring and a connector, you have to pull the wire harness back towards the door to get to the connector as it is located just inside the car itself, you do not have to remove the door cover. This connector is a known cause of problems as one of the wires in this connector is the serial data highway wire. You could also have some kind of power distribution problem or grounds. Good luck

I don't know if there is a dedicated hard wire from the door latch mechanism which contains the door ajar switch that is wired out via the wire harness, or if that information is passed on via the serial data highway.
