No fire where ?? at the plugs, coil wire at coil, coil wire at dist.??Do the primary wires to coil read 12 volts?Start at the source before you start throwing parts at it.You sound like a pro "mechanic", "I think this is the problem"What brought this "no fire" situation on. Did it just magically not start or did something else bring it on ? Dignose the problem before spending money.
