Ignition woes

If you are changing the problem like this every time you fiddle with the bulkhead connectors, then you are probably in the very close neighbourhood of the problem! Pay attention to each and every terminal, especially J3 (14ga, brown, middle connector) and J2 (16ga, dark blue with tracer stripe, middle connector) in both sides of the bulkhead disconnect; sounds as if both of them have loose/sloppy, corroded, or otherwise imperfect connections.
