whats the fuel pressure?
whats a compression test on all 8 cylinders show?
wheres the timing set?
do you now how to correctly set valve preload?
buy a CHEVY SHOP MANUAL FOR YOUR YEAR CORVETTE!
set and verify your ignition timing, pull trouble codes,set your tps and iac,, then check for vacuum leaks on the lines and intake,then get out your multi meter and verify all the sensors, chances are good its a defective sensor,
a logical step by step approach will lead you to the problem,
youll be amazed at what youll learn reading links.
use of a shop manual and multimeter can be very helpful,
its just a simple process of testing sensors , fuses and fuel delivery voltage and circuit resistance
once you get the vettes engine running,
fill the tank with fresh high test fuel and change the fuel filter and spark plugs
,throw at least two different brands of injector cleaner and 8 oz of marvel mystery oil in the corvettes fuel tank
,this tends to reduce or eliminate a great many minor tuning issues that result from partially clogged injectors,
that are common on a corvette thats not been run in months.

fuel pressure, oil pressure, cylinder compression, and ignition spark at the plugs and valve timing
pull trouble codes
