What you need to do is take the distributor out and by hand turn the engine so that Cylinder #1 is at TDC on the Ignition cycle. YOu can determine this by watching the valve rockers. Once the Exhaust valve has opened and closed, the intake valve should open and close. At that point watch the crank balancer for the "timing" marks to line up. Then install the distributor with the cap OFF, watching the rotor. It will rotate as you lower the distributor so you will have to rotate the dist shaft the right amount before you try to put it in so the rotor will point to #1 on the cap when it is all the way in.
The distributor cap and/or the ignition rotor most likely have a crack somewhere and the distributor cap should be replaced along with the ignition rotor. The ignition module could have been damaged as well as the ignition pick-up coil/stator and if replacing the distributor cap and ignition rotor does not solve the problem then the ignition module or the pick-up coil/stator assembly inside of the distributor is also most likely damaged and the distributor will need to be replaced. There is a certain procedure for removing and replacing the distributor, and the ignition timing is not adjustable and it is not set using a timing light or with the engine running, and if you do have to replace the distributor Let me know if you require the procedure to properly remove and replace the distributor or if you require any further assistance.
moisture in your cap causes oxidation. You should check to make sure the seal for you distributor between the distributor and the cap is still good.
Also a faulty ignition system such as a problematic coil or high resistance in your ignition wires can lead to ignition related problems. Doing a partial tune doesn't always work. Do the wires, plugs, cap, rotor, fuel filter, air filter, PVC valve and depending on the mileage the ignition coil.
Try changing the fuel filter and checking the fuel pressure at the shredder valve. The readings should be 60 to 65psi with the fuel line pressurized with the engine not running, once the engine is running. It should drop by 5psi. Start with the simple things first. Keep me posted, be glad to help.
Remove the distributor cap, so that the rotor is visible. Have an assistant turn the ignition to crank the engine over. If the rotor does not turn when the engine is cranking, then you need a timing belt or chain.
