Cylinders 1 & 4 as well as 2 & 3 fire together in pairs, if you don't have cylinder 2 then you pretty much don't have 3 either, and the same with 4 and 1. Waste spark ignition system. Pretty much anything wrong with one half of a pair there and the other half doesn't work either as the completed plug grounded circuit requires BOTH plugs of a pair to fire to work right, one doesn't fire then the other severely hampered at best.
Sure you got plug wires on right? You could have a couple wires mixed up and only one coil or whatever bad.
