This is a thread I wrote on the starter relay mod from the other forum,not sure how long it will stay here but I gave it a shot. http://www.corvetteforum.com/forums/...made-easy.html

Cool weather is here now. Haven't had the issue come up again. Located the wire to jump it. Battery was low, once charged it fired right up. When the prob started it seemed to happen after running a while in really hot weather. Might not show up again until then. If I figure it out, I will post what I find. Might be a good idea for the switch bypass anyway. I'd rather have it if it works, but I don't know if it's worth the gamble since so many see it as an issue.

Add the Relay and recondition the starter.....I do it to ALL ZR-1s....I also Block TB Coolant at the Injector Housings and add Differential Drain on ALL ZR-1s

Starter, Starter Relay, Wiring Harness, Battery, and Plugs Tricks

Tech Info - LT5 Added Systems

I do those modifications no matter the mileage and no matter if they are not in immediate need of the modifications

I had a no start ONCE. And once was enough. Embarrassing to say the least, and had I not had a bunch of club members there willing to push the car (It started right up when I popped clutch) it would have been an expensive tow bill.
I did Dyno's relay shortly thereafter, and also put in a new battery. Never had an issue since. The good thing about the relay system is that if it "no starts" again - I know I have to excavate the starter and clean the contacts. Takes a lot of the guesswork out of the diagnosis..

Basically if you can hear a clunk at the starter, but no crank, it is a starter issue...no clunk probably one of the other switch failures......

I had a no start condition after winning best in show engine....kinda funny..

A NO Clunk could be a stuck Solenoid.

That was Best in Show. Not Best in Run.

That's funny. The first thing I pictured (which I'm sure isn't true) is that you had spent all day pressure washing the engine to get it looking perfect. :-)

Warm weather is back and so is my issue. Happened a couple of times. My Uncle has as C3 and the guy helping him with it has worked on a ton of C4s and said my problem sounds like VATS. He said a lot of times you can wipe the key off and try again after 30 seconds and it will work. Haven't tried that, but really sounds like it might be my issue. Ordered the bypass from Ecklers and I will see if that works. IF not, I will add the bypass relay for the clutch switch. Will see how it goes and update accordingly.
