Try spraying some starting fluid into the TBI to see if it fires off. If it does not start, then you may not have spark. Check for spark. Also make sure the fuel pump runs, primes up when the key is turned to the on position. May have lost power.

Try the ground on pump. Sometimes they don't get tightened all the way
