1985 corvette wont start.
I got a 1985 corvette that was sotting for 12 years. About a week ago, i took all the old gas out, put fresh gas and she started right up, no problems. The next day or two car sounded better and ran better. I drove it maybe 50 miles in the course of 2 days,
well 2 days ago I went to start it and the idle was terrible, car barley stayed running, changed the tps, now the car wont start, it started once while i pushed the throttle but ran terrible, now it shows no signs of starting.
today it had low spark so i changed the icm and the spark is a lot stronger now,
Ive got spark coming out all wires, plugs are good and i have 48psi to the rails, and i pulled spark plug number 1 and it had some fuel and wasnt burnt out. Im prob grabbing noid tool to check injectors, if That doesnt work, shes going to a shop but i wanna avoid that. Any help is appreciated thanks guys.
ps motor is the l98 and auto tranny

Welcome to the forum.
Don't know how you're checking the spark but remember that a weak ignition system will look good on an open spark plug but will not fire when it's under compression at a higher pressure. since you seem to have fuel and air then I would suspect something in the ignition system.

yea i am to i sprayed gas directly into it and still got zero response, the plugs caps n wires are 7-8 yrs old but it sat for 8 of those years just ran for 2 days so unsure if they have went bad but u see no corrosion and i changed the the icm in the distributor yesterday, unsure what else i should look at or do next.
