The car turnsover but wont fire up. Sometimes it seemslike it wants to fire but doesnt. could it be bad wires. i think i'll try putting theold wires on andsee what happens. It should be in the right order i pulled them one at a time. I dont know what the gap should be how do i find out. I'm new to doing this stuff myself but want to learn. This is a rebuilt 74-75 350
