No start need help
Every now and then my vette will not start. Everything will come on radio,fuel pump, dash, and so on. But, the starter will not turn her over. But if I wait an hour or more and try again it will start.
I have a 1990 L98 6speed. Could it be the starter, computer, VAT, or injectior?
The starter itself was the problem.

If it only happens after driving and the engine is still hot the starter may be shot. The heat from the exhaust can cause the starter to stop working. I have seen heat wraps to prevent this problem but have only had one starter go bad in over 12 years so never tried one.

Ok with a drum roll please.
The item to blame is the new starter that is not even a year old put on but Shamco (aamco). So in the morning Ill see if it a bad wire, or worn part.
I'll keep you all updated.

Why are you so sure, you have no diagnostic evidence its the starter. In fact the evidence you have is that VATS is likely the cause of your no starts. When it won't crank, unplug the clutch safety switch and install a jumper across the socket. You should have 12v on the jumper with the ign in crank position. If no 12v, then pull the kick panel above the drivers feet and find the 2 wires from above the steering column that go to a 2 pin plug and unplug. Insert key and measure the resistance across the 2 wires from the steering column, it should measure the same as the key pellet. If more than 4% error, you need a new ign lock which will have new contacts that make connection to the pellet. If more than 4%, connect a fixed resistor the same value as your pellet across the two contacts from the wiring harness and attempt a crank. You can even jump 12v to the clutch safety switch jumper you installed which will force the starter to crank, this will prove the starter is or isn't good.

So I'm 100% sure it was the starter.

this is a lengthy debate???? the highest probable is the Starter solenoid
OP states if he waits a hour + good to go
if it was the key resistor it would not be intermittent... possibly the Ign switch.. not common
make diagnostics quicker... Neutral and jump the solenoid

When I first put my pace car on the road after a restoration, I grabbed the wifey and drove in 95+ deg temps to Newport RI. I had to stop after crossing the RI border to actually put the T-tops ON due to the brutal sunshine. When I went to restart......CLICK, then nothing. Fortunately I carry a Ballpean with me. A few whacks on the starter and off we went. The first thing I did after getting home was replace the starter and wrapped it with heat wrap. No more heat soak from the headers. All was good.
