No spark 67 valiant

This all getting complicated for the OP. Mulimeter & test light should stay in ther tool box at this stage. Neither can determine if a condenser is bad or if the coil has an internal failure.
Mostly likely cause of the problem is ign, fuel or less likely timing chain jumped a tooth [ hard to determine ].

So concentrate on ign/fuel. You go the END of the line to find where the problem is. Then work backwards from there.
So use post #10 to do that.
