jeff try switching the 2 white wires on your connector for the distributor. you might have mixed them up. remember one wire with a red mark on it. also look for any loose connections,specially the groundings. check your fuses, it might have burned.your hazard fuse #10 in the engine bay, its most likely that might have burned. check other fuses under your steering wheel too.

if all fuses are ok, what you want to do is try another si ecu. peace and good luck.
