Default 4.3 help no start

I just bought a 94 s10 blazer for a donor engine swap for my 4runner. The engine is a jasper reman and was running perfect about a month ago the fuel spider has been replaced recently also . I went to pick it up and it will not fire just cranks . I tried starting fluid in the throttle body and still nothing . It has only been driven in and out of the garage for about a year and normally starts right up . I have no experience with the 4.3 so any ideas ? I was thinking rotor and cap ? It has some spark when i cranked it with plug wire off to ground. I need to get this home and start tuning it up before pulling it so any ideas where to start?

I had this happen on a 93 4.3 truck..
1: Check coil, I replaced mine and the new was bad too :) (turned out to be the whole problem)
2: Ignition module
3: cap and rotor

If you need to just get it running, you can try sanding/clean corrosion off the contacts in the cap. Also check the coil tower & coil wire for any signs of corrosion. Also for the love of god dont buy a Vato Zone cap & rotor
