Default Starting problems C-5 Automatic 2004

My C-5, automatic trans. coupe, is having the problem that bulldog2600posted about a six speed. My car will not start, but everything comes on normally, except the starter. No sound, no starter. If I wait a few minutes, it will start. I know it could be the solenoid, but could it be the trans. switch or whatever interfaces with the trans./starter/key/computer? Will diagnostics show anything? The car had the exact symptoms described. I live in a AZ. We do not have moisture with which to contend, so it probably is not a ground connection. Do the trans. or ignition switches cause trouble? The car has 24k on it.
Thanks
JAS

It most likely the solenoid. Autozone has one off a 1999 Taho that will fit. You just need to get a connector pigtail and splice it on the small start wire. The replacement solenoid is around $50. Far less than a new or reman starter.

Heres the schematic that you can use to test voltage at the Theft Deterrant Relay.

It is possible for the ignition switch to be the issue. If the contacts are burnt in the switch, it will cause the same issue.

Before you get too involved in replacing stuff,,,check out this post that I made to repair your own ignition switch:

Default 2004 starting problem

Thanks for the information. I will print out the schematics. As I have thought more about the problem, I wonder if the security system might have caused the problem. The car starts right now. The dealer said drive it until it will not drive and call a tow truck.

If it was the security system stopping it, I would think the security light in the IP Cluster would have been flashing.
