It started yesterday, it had trouble starting but I assumed it was a combo of it sitting for a week and it was a cold morning and weak battery, I drove out to town to pick up a trailer, and when I pulled into tractor supply I noticed the water pump was leaking, I never shut it off from when I left the yard till I came back, I parked it in the middle of the yard to shuffle some other things around with the tractor and went to start up the topkick and it refuses to start. I have come to the conclusion that it has no spark, I’m not much of a tbi guy myself, and I’m honestly not super familiar with solid state distributors either. Any tip on where to start now?

The HEI module in the distributor is prone to failure on these. I don't know if that's the problem, but it's worth checking if you haven't already fixed it by now.
