OK - got a new battery this morning. Unfortunately, still won't crank. Is it possible that there are fuses that have blown on the ignition side of things that I can try replacing?

Unfortunately OP has no electrical experience so that won’t work…he needs to tow the car to a shop.

Is the ignition switch repair an easy DIY? Wondering if I should try that first given that I can't get the vette out of the garage at the moment.

I can try swapping out the fuses if that could be the culprit - I see the relevant fuses in the passenger kickboard and can go grab some new fuses today to replace.

If you are going to repair it you might as well change it !!…if you knew how to use a DVOM you can verify it’s 100% an ignition switch…”test don’t guess”…a tow company can get your car out of the garage.

is it hard to learn how to use a DVOM? I'd like to think I'm reasonably intelligent.

You can most of the time tell it’s a fuse by looking at it.

So again I ask if you can hear the TDR click on when you turn the key to start the car? There is fuse 52 it's a 60 amp fuse that supplies power to the TDR, if you jumper the red and violet wires at the TDR socket the starter should energize, extreme caution when doing this, make absolutely certain the car is in neutral because this bypasses the requirement for the clutch having to be depressed. This simple test will determine if the starter or solenoid are the cause of the no crank or the cable connections at the starter solenoid are corroded and or loose at the starter solenoid.

I think I can hear the click. Going to get it towed to a shop tomorrow.

I got 14 years (2008 - 2022) out of my Optima Red Top, driving my C5 approx 125,000 kms during that period. I only replaced it due to everyone else telling me I was crazy not to replace. It became a running theme at every cruise night. I replaced in 2022 with another Red Top.

Confirmed I hear the TDR click so seems to be pointing to the starter/starter solenoid. Car is on its way to the shop - will report back once I hear anything just to close the loop. So odd to me that this would happen within a week of purchase and after a 9hr roadtrip but **** happens.

Hopefully your shop can diagnose it correctly with just one part…the cars starting system is pretty simple to diagnose.

To the OP, it's not surprising that this would happen, heat is the enemy to starters and starter solenoids. The nine hour road trip didn't help matters, especially if the starter/solenoid was orginal equipment .

This is what I was thinking as well. Guess it was probably on its way out either way, assuming it’s the starter/solenoid.
