I guess you could have the ignition analyzed on an oscilloscope. Maybe a tech could see something then. I always heard the only gap was the spark plug gap-the rotor has no gap-are you sure you got the correct rotor? And does it touch the top distributor cap coil wire tower?
Let us know. It is a mystery worthy of a solution.
Had an 84 silverado 305 that did the same thing. Try giving it a full tune up. Plugs, wires... Mine turned out to be fouled plugs. I didn't find that out till after i tore it down & put a timing set in it. Wasn't getting good enough spark.
It sounds like u have a cam correlation problem... Take ur cap off mark where ur rotor is pointing on the dist. Mark the firewall where the dist plug is pointing take the 10mm bolt out n look @ the dist gear and see how bad it's worn!! When u take the cap off some times they're so bad when u move the rotor u can tell the excessive play hope this helps!!!!
you said you repl dist cap that means you don't have a crank sensor you have electronic ing module. remove your elec ing module have it tested most auto parts stores could test your module, or check your coil at the neg terminal. should have power. if not you lost your primary volt from your batt.your secondary power is coming from your electronic ing module from the module to the pos terminal on the coil, when the eng cranks,from the coil to the dist cap , from the dist cap center to the rotor then out to the plugs,this all happen pervided the timing belt or timing chain is ok. the cumbustion chainber needs 3 things , thats fuel, air, and spark.
Pull the coil wire out of center of distributor cap and lay it close to where you unpluged it from distributor cap, and turn over engine if coil is good you will see the spark jump. If no spark coil bad.
replace the ignition control module,I recommend a new one,if you order a rebuilt dist.it comes with a used one that only passed cold temp bench test they usually have problems once the car warms up. so get a new one!good luch let me know if you need more info have a good day DB
