Code 21 -Ignition Signal / Where to begin?

[DaydreamDrifter]

Any suggestions on what to look for?

coil, module, cas, distributor, wiring, etc.

First i'd look at my wiring... just make sure that it's not cut or frayed anywhere... make sure there is a good connection on EVERYTHING. I had an ignition signal problem and a wire was loose to my aftermarket coil. I got rid of that sum ***** and put the stock one on. make sure all your grounds are there too. Your ignition coil could have gone bad. Oh BTW. C if you're getting spark and write back.
