could be the wires. pull the #1 plug, leave it hanging from the plug wire with the electrode laying up next to the exhaust manifold and have somebody crank the motor over. watch for the plug to spark. is it nice and bright blue? or kinda yellow? or none at all. start there and tell us what you got.

could be a wire but all the wires shouldnt go bad at the same time but enough bad wires will not start it, timing is hugh and if you just changed plugs can make a huge diff, oput engine to top dead center then adjust cap bad plugs can have affect as well also try using a diff cap a hair line fracture will kill the spark as well...................good luck
