Have you check to make sure the distributor rotor spins while cranking the engine?

Go call SATURNTECH9, if the rotor spins I would check for power at the positive side of the ignition coil. Here is guide to help, it is the pink wire, if there is no power please check the ECM1 fuse 20 amp, in the fuse panel under the hood. This guide can help
