never know patrick, maybe they died...
sounds like you need to take an emotional sensitivity class to correct this behavior

No excuses, they can post from the other side.

Apologies...tucked the car away for the winter and haven't touched it since. I may poke around at it a bit more as it warms up, but I also currently have it listed for sale.

When I had my 84 (automatic, not manual), I had chronic trouble with the starting circuit.
A few times I jumped the starter solenoid from above using a long screwdriver. It's a bit of a reach on the forward side of the engine but I remember not having too much trouble getting to it. I certainly never had to do it from underneath. This is the most direct way to bypass the starter circuitry. As always, make sure the transmission is not in gear.
Jumping the starter solenoid bypasses pretty much everything. If it still won't crank when you do that, you're down to just the battery, the starter, or the battery cables as suspects.
There's an alternative way to do this, which is slightly less direct but it's maybe easier (it certainly is on V6 cars anyway). I know this is valid for 1986 - but I doubt 84 is any different. I don't have any wiring diagrams for 1984 to verify:
If you attach a length of wire to the Purple wire of the clutch switch, and touch the other end of that wire to +12V (directly to the battery would be ideal if you can reach that far), then it should activate the starter. Again that bypasses nearly everything so make sure the transmission is not in gear.
I started my 86 this way about a year ago (auto, so the purple wire was at the neutral start switch in the trunk).
However - if you had that remote start switch connected correctly then it would have the same effect as these other methods. So what I wrote above is probably redundant, but maybe helpful to somebody else reading this in the future.
At this point I think you should remove the starter and get it tested.
A starter draws a ton of current which is way more demanding on the battery cables (and their connections) than anything else. If the cables are going bad (or they have a bad connection), you'll have problems with powering the starter when everything else still works fine. You mentioned earlier that the fuel pump runs, so we know that the cables are at least working well enough to power that much. A multimeter uses very little current that doesn't stress the cables at all, so I don't think it will see any hint of the resistance that the starter is seeing.[This message has been edited by armos (edited 03-19-2023).]
