Well this is intriguing.
We HAD a 2004 Duramax that we loved. We were away from home with the 5er and the truck wouldn't start. Wait a few minutes and away it went. Down the road it did it again. Call a GM dealer and they arrive and it starts. Grr. Same thing again only this time they couldn't get it to start. Battery and cables all good. Relay switches all good. New starter, new ignition switch, remove add on remote start, and numerous other expensive fixes and it still would do the intermittent no start deal. Turn the key and nada nothing. Totally dead. Well its traded off on an 11 Dodge ram (doesn't have half the pulling power) and wife decides she is in love with an 04 Tahoe. Perfect for her and the zoo. Oops we forgot about the no start problem and now 8 months later it is doing the same thing. HELP. No clue what to do and as seniors cant afford to replace everything in the Tahoe. Did ask local dealer and they say for 140.00 an hour we will check it for you.
Any ideas out there?
