Hello and Welcome

[Stu]

Right now back to your problem

I am guessing you have two coils and both feeding two plugs each? which plugs run off each coil?

[oldjohn]

yes the top one feeds1&4 the bottom one feeds 2&3 no spark at 23 both coils are new

[Stu]

have you checked the power to the coils?
