Let me first say, you have been very patient with bartamos and he has been very patient with you. Usually this would have gone off the rail quite awhile ago. That being said and not wishing to step on bartamos’ very comprehensive testing, do the following. Remove #1 spark plug. Place your thumb over the plug hole and have a helper bump the starter/engine around til your thumb gets pushed off the hole by the engine compression. Look at where the timing mark is. It should be pretty close but can be an inch or so one way or the other from the zero mark. Now remove the distributor cap and see where the rotor is pointing. It should be pointing very close to the #1 tower. If not, and you have never removed the distributor, rearrange the plug wires properly and try to start the engine. If it doesn’t start do the test again. It is entirely possible that the timing chain has jumped. Good luck
