    Have you checked to make sure you're getting spark? Hook a timing light up to one of the plugs and see if it lights up. If not, the most likely culprit is the ignition module located under the distributor cap.

    Does the fuel pump go on when you turn the key to the on position?

    Did you check your fuel pump relay? On my 88 it was on the firewall over by the air conditioner.
