I bought a 2005 Colorado 3.5L. On Occasion the truck will not start (will not turn over). All the gauges go from working to not working while in this condition, low fuel, ABS, Security light. When/If I get it started additional symptoms are the A/C doesn't work, door locks do not lock/unlock when going in/out of gear, ...etc. I am thinking my CPU is going bad. Any ideas?
