You need to purchase a Field Service Manual (FSM) for your exact year Corvette and go to the "no start" flow sheet and follow along until you find the problem. There are so many reasons that it will not start that is nearly impossible to diagnose the problem here.
You are also posting in the wrong section as this is C4 Parts for Sale/Wanted.
Try looking at www.half.com or www.amazon.com for the manual.
Narrow the problem down and then ask more specific questions in the C4 Tech section.
Good luck and be sure to mention which year your C4 is when you do ask questions in tech.

Art,

Could be as simple as a poor ground on the starter or the battery-engine block ground. If the starter is new (and good) and is properly wired, two other checks would be the ignition switch wiring (continuity to solenoid relay, etc.), or the more nasty seized engine. You can check that one by removing the spark plugs and trying to turn the engine over by hand. Then there's the neutral safety/clutch depressed switches and wires, fuses, relays, anti-theft system...
The service manual is a good idea.
