Did you check for spark at a plug wire or at the coil wire? Check at the coil wire,if there is spark there,the ign rotor is bad,very common to have the hot spark "drill" a hole thru the rotor to the dist shaft. Also check for play at the rotor shaft. Distruibtor bushings tend to go bad,making the trigger wheel hit the pickup coil,killing the spark.

The problem is either your fuel pump relay is overheating our your fuel pump is over heating. They also have the problem with the wire connector on top of the fuel pump melts. This is a known problem with them, when you but a new fuel pump they give you a new connector and a service bullentin regarding this problem.

Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..
