sometimes..a weak ignition coil will also cause this
it tests good
but,,the problem is right there
what test good?
replace the rotor and cap..if this dont let you get a spark to the wires....replace the coil..even if it does ohm well
the ohm test isnt always true
sense you can not duplicate the high voltage
