No spark

Hello, I have a 91 sc and I took it out one night and then parked it. Went to go start it in the morning and it wouldn’t start. Checked fuel, replaced fuel filter, then went to spark and I have no spark. Replaced diss module and no help. Next thought is a crank sensor but don’t want to pull the trigger because they’re expensive. Any other ideas before that ? Thank you.

You'll notice in the chart that replacing the crank sensor is the last possibility after checking everything else

Oh Yeah I definitely agree I was Skimming over that chart just out of morbid curisouity and didn't see coil pack but I may have just overlooked it so I was just throwing that idea out there

Checking coil circuits is N12 & N13. After reading the chart again, I see I was wrong. N3 says replace crank sensor if that test fail's, but it also says replace crank sensor again in step N30(last step) which is why I thought crank sensor was the last possibility according to the chart.
