i see everything but the simplest and free things to do.
check the grounds. honestly, on these cars, they are crap 100%. I would recommend they be changed to something a little larger and i added one straight looper from the back intake manifold to the stock block ring, back to battery.
if you have a continuity tester i can assume you have an OHM meter as well, start running through grounds and if the resistance is greater than ~0 on a straight battery or chassis ground i can assure you its poor contact.
use Napa's "Liquid Copper Anti-Seize" on all the threads of all grounding harware, gives you much better contact surface area.
This is free and easy as long as you have a good tester, it might save you money instead of throwing parts at it non-stop and losing money and time.
Also check to make sure your ignition tumbler does have completely worn out contacts,
