I am a bit confused about the statement:
| Quote: | Turns out mine has current when ignition's off, but when ignition on, it no longer has current.
Furthermore, instead of having 6V on 15 with ignition on, the ignition coil has 11V. |
Having 11V (more or less full voltage) at key-on vs. 6 won't stop it from starting; it'll give a hotter spark, might eventually wear out some components but definitely will spark.
The question was asked: does the inside of your distributor look like the picture above? This is critical to us understanding what your ignition system is.
To check if there is spark, like Chuck (Fifty50Plus) said, you need to have a friend crank the motor (ignition turned to START, starter motor turning) while you have a spark plug in the end of one of the ignition leads, with the threads of the plug touching the engine (I usually use the top of the intake manifold).
It sounds like you still haven't performed this step.
It would also be appropriate, when trying this test, to verify what voltage you have at the ignition coil #15 terminal WHILE CRANKING. This uses a different circuit than when the ignition is just turned on (to the RUN position).
Also, can you confirm that you have a thick green wire (shown in the pic above, actually has two contacts in the connector) plugged into the side of the distributor?
If you want to be successful with diagnosis, you MUST be methodical. You cannot omit any steps, or you will NOT find the problems.
