look for corrosion, alot of times that pin is corroded, you can sand it and put dielectric grease on it

Shouldn't matter. If #1 isn't firing, then #3 shouldn't be firing either. They both fire at the same time. It'* either a bad sparkplug wire or a REALLY bad sparkplug.

How did you check for spark? With a spark tester at the end of the ignition wire or at the #1 terminal?
