Hello,

It will be a good idea to check the distributor. Check for any play on the shaft.
It will also be helpful to check the adjustment of the distributor.
If there is play on the distributor shaft it will throw off the igniting timing.
Having a bad distributor shaft can trigger misfire and no start.

I have attached distributor diagrams for your reference.

Please let me know of any questions.
Thank you.
