I need help with no spark in 88 Corsica

I need some suggestions on what else to try. I have an 88 Corsica and #6 is getting no spark. I have tried a few things. I replaced the spark plug, the spark plug wire and the coil. The same problem is still going on. What else should I try?

Thanks

Bets bet is to remove the ingiton module assembly, and take it to be tested. You usually have to do this anyway to replace one of the coils as the entire assembly will come out with three bolts (10mm I think) then unplugging wires. Take the module to Advance or NAPA and they can check it.
