Try swapping coils with a good cyl and see what happens.

Do you think it could be the power pack.

Maybe it has dirty contacts?

Without checking with the proper test equipment, I'd have to guess a bad power pack, timer base or wiring.

you can change the wires from power pack to coils around & check it this way all it does it just changes the firing order around but put them back like you found them when finished , i do it this way then i know for sure .
