Check your battery to solenoid cable.
I was having an issue with starting my '05 and couldn't find the problem. I finally took it to the dealer 
, and had them look at it. It ended up being a loose connection on the battery to starter solenoid connection. The connection had been loose so long it had damaged the post so much it couldn't be tightened anymore.
I've had NO problems with the car after they replaced the starter and battery cable.
It sucks that it was something as simple as a loose positive battery cable, but as expensive as replacing the entire starter and cable. I think there might have been a service bulletin about it. I'd recommend every C6 owner to at least check the connection so they can catch it before the vibrations damage the solenoid post.

Easier to access from underneath BUT.....be very careful to disconnect the positive terminal at the battery before attempting to tighten the connection at the starter motor. If you were to inadvertedly touch a ground with whatever tool you're using on the connection. you'll get the SHOCK OF YOUR LIFE!

Removing the NEGATIVE terminal from the battery will also save you from a short. You may have to re-index your windows, and may have to reset the clock on your radio.

LeeYou DO have to re-index the windows, but the clock will retain its settings as will the radio.
OP, good post. I need to check mine, as well as check the routing of that cable, particularly since I have headers. I have read multiple times of cars not starting due to this cable getting shorted out (which is a fire hazard too).

No need. Takes two to tango. Just remove one side, but always take off the negative as if you hit the wrench on any metal it's no big deal. With the positive, if you touch the wrench to any metal it'll spark and surprise you.

I've replaced a few starters already on customers cars for this problem. I think that is so much stuff tied into this terminal it gets hot and breaks down,thus causing the cable to come loose. Had one customer that had a high end audio system and his came in at 40k w/ the stud burnt out at the solenoid. Others for intermittent no start have been in around at 80kmiles.

Haven't tried to replace the solenoid only. When you have customers that want their car back asap they don't care about saving money. It's fix it and call me when it's ready deal.
I know a shop close to me that services alternators and starters. Have not tried to run a solenoid through them. Just had them repair a 225 amp alternator for a high end audio 2002 Camaro SS that had the alternator repaired.

Can this loose wire also cause my lights to pulse? I haven't checked it yet but it's on my list. I already checked the battery and alternator and they seem fine. Of course I always have the battery on a tender when I put it in the garage so I left it off for a day and see what it says after 24 hours. If the wire is good and tight then I'm thinking it may be the voltage regulator.
