82 continental ignition switch problem ?

hmm got about an 82 or so lincoln continental and i am told that it doesnt run unless the key cylinder is all the way in the cranking position.

just started doing this out of the blue for no reason,
daily driver
i am thinking that the ignition switch is broken/worn out

what do you think?

it is holley TB fuel injected v8 with original ignition control module box

in the past it has had issues with the terminals on the coil and the harness plug for the control module that ive had to repair/clean, which were causing no start condition. and it has been fine for a super long time after that, and now apparently has a new different issue/cause now.


which wire should be hot in run position(from the ign switch) to feed this electronic ignition and allow it to run.

thanks

I tried to find a source for a wiring diagram for your car but failed so I cant tell you what color wires to check. But you should be able to match the main wire color from the ignition module to the switch at the base of the column.
A couple things to check:
- adjustment of the switch, the ign switch should be adjustable via slotted mounting bracket. If the switch has moved at all, it may be possible that when you release the ign cylinder from "start" to "run", that the switch is returning too far and shutting the engine off.
-the switch itself may be bad, this is where you will have to determine the proper wire color and check power at the switch out to the ign circuit. The wire from the switch to the ign module is apparently fine if the car starts while cranking over.

Of course this is assuming that the ignition is what you are losing, could be the fuel circuit shutting off, which very well could be an ignition switch problem also.

the early 80s Ford ignition switches where known for problems such as meltdowns and sticking on and causing fires , I would check the switch ( at the base of the column on topside) to see if the screws came loose that hold it in place ( which means you can realign its settings and tighten the screws ) or see if it has signs of melting or damage , and when it doubt change it out , they have revised them to take care of the past problems .

The four tabs that hold the switch together also have a tendency to open up and the switch falls apart internally, which can also short and cause a fire. Ignition modules were also prone to failure and can cause the same issue. Check the ign switch with a test light to verify you have voltage in the run position compared to the off position. One wire (don't recall which) should have 12v in the run position. If this is not the case suspect an ignition switch problem. If you have a wire with 12v in the run position then suspect a module problem. You will need a known good ign. module to try. Never hurts to have and extra module or even a junkyard distributor in the trunk for that vehicle.

supposed to go and retrieve this car in a few days to work on it and figure this out. i dont have any ford modules around especially this style hmm. ign switch failure seems most likely at this time though

i have found wiring diagram for it so i think figuring out the cause will be not too difficult.

hopefully

thanks
