Have you separated the connector that ties steering column wiring(from ignition switch) to wiring harness that feeds starter/ignition circuit?
There are 6 main wires, blue, red, brown, yellow etc. One of these 6 is only energized when ignition switch is in 'start' position thereby bypassing ballast and going directly to coil positive. I forget which one,,,test light or schematic will tell you.
If connection for that wire at the connector is not solid, wiil cause exactly the problem you are experiencing. Same goes for bulkhead connection for this wire.
. Ok I will try to figure out what wire that is and see if there is 12 volts at the ign. Switch. Where will this wire be coming from, the starter relay possibly}?
Separate the connector. Take your test light, ground it to known good ground. Then turn ignition switch to start position while probing each wire in connector exiting the steering column.
The one wire that illuminates the test light as you turn switch to run and goes out as you release switch is the wire in question that bypass's ballest.
Test voltage with meter on this wire while switch is in run position,,,should be about 12 volts.
Plug connector back together and test/probe/meter this wire now on the dash harness side of connector. Lost voltage indicates problem at connector joint.
Also you might meter this wire from connector to where it connects to coil. Should be almost no voltage loss.
Good way to test continuity of this wire, ground it at coil. Probe at connector with meter sending a blast of current down it while other meter wire is grounded. Could be a cold flow short in it or problem at firewall.
Good luck. You are making progress whether you yet know it or not.
