tom's spark outputs cross on his board, your's don't.

so his sparks are reversed from yours. try loading his map and starting his car with the spark plugs swapped around. that can easily rule out the MS or Harness.

for S&Gs, what color wire is next to the red 12v on your boomslang?

 

at the db connector?

 

Try switching the plug wires on the coilpacks and see what happens.

 

no, on the boomslang...do you have a green/white wire next to the red one spliced off the boomslang?

 

I have it set up just like your "how to make a boomslang". brown wire 3 over from the red, and the green/white right above the brown.

 

that's why...that's not how my diagram is. swap you plug wires and try again.

then again, last time i saw tom's MS, the coil outputs would have worked if your harness was built that way.....

 

?????????

 

just kidding.

 

damn, I thought I had a solution haha. This sucks!

 

here's something i dunno if we ever thought of.....does your 93 have sequential injection?
