65 cuda

im lost guys & not a mechanic , a very shade tree, my interior lights quit coming on all of a sudden , noticed a guse was blown , found out the plugs that were in my 273 were too short , put longer plugs in , no start , figure hey its just my luck the coil thats on the car **** the bed its been leaking fluid anyway, 28 bucks later , new coil still no start , im getting fire to the coil but none out to the plugs, what the hell would cause this , 8 broken plug wires that are less than 9 months old ??
