Dreaded C6 won't start when I push button
for a month my 2007 Z06 would start sometimes and then sometimes when I pushed the start button just a single click and nothing. Let it sit for a bit and it would start most of the time. I could go several days and no problem, but as soon as I plan to attend a show or cars and coffee then she would act up and have to be push started.
Today she died and would not start at a popular breakfast spot here in town, the car attracts a lot of attention and its embarrassing when it wont start
Read all the threads on CF and checked fobs, put fob in glove box added new fob battery used both fobs, nothing.
Checked all battery cables and connection, replace with New battery, nothing.
I have all accessory power, everything works, wont start, jus 1 single dreaded CLICK
I have tow loops on car for track days, mostly used to pull start car these days, great investment.
Pulled it and it started of course, now I have the first warning mess ever" service charging system"
got it home, checked alternator, all is normal.
put it on jack stands get underneath and find that the front of the solenoid has sheered off and the starter wires still attached to the screw and nut in place are just hanging down.
How did this happen? and why did it start for a month sporadically?
anyone else have this?
Some additional info: This is a Mallett Z06 with Kooks Headers, I have about 27k miles and this is the 3rd starter. First one got too hot from headers and burnt up. Second one I had wrapped in heat tape and the starter wire nut loosened and arched and burnt up wires. Now this one has blown the entire end off with wires still attached to each other on the screw with nut tightly in place just free balling

Those headers must be real close to the solenoid. My AR headers have about an inch of clearance at the closest point to my starter; but maybe the clearance for you using Kooks is much tighter. Looks like a custom heat shield is the only way out for you.

I had this EXACT same issue and it turned out to be the heat from the headers. A brand new starter, jet hot coating on the headers, and a heat shield... She's back on the road. Quite a frustrating experience. I definitely recommend doing both of the above if you've not already.

Is it really a dreaded C6?
I think the two above posters have the correct diagnosis: heat from headers melting starter solenoid. Happened to me too. Don't worry too much about difficult or redundant solutions. Buy a $100 replacement starter at O'Reilly, cover the solenoid with high temp heat shield tape (available on Amazon), and swap the old part out (not so hard, even without dropping headers). That's worked for me. No custom heat shield or new coating on headers. Also pop the hood if possible in situations when you shut the car down soon after spirited driving.
