So, the key thing is simple - there is a circuit somewhere that isn't connected. When you crank the engine, it gives power to both the starter solenoid AND the ignition circuit, etc... When you let go of the key and turn it to run, there's no power (in your case, normally there is) going to the ignition/fuel pump or some other thing.

First thing - test at each component with the key in the "run" position. Check at the main relay, the ECM, the fuel pump, and the ignition coil. You'll feel really dumb if you go through all the work to trace wiring and find out that it's something really simple (Been there, done that... got the T-shirt, somewhere.)

If you're not getting power to any of those things with the key in "run", chances are, you're either missing a wire, or you have a fault in the wire.

Your heater control panel is probably constantly on because you have a wire switched somewhere. If you can post any details about how you did the wiring (which wire color/pin/location from each harness you connected) we may be able to help out better with that/those situations.

In any event, no, you should not keep starting the engine if you can't keep it idling for any length of time (Idling with the starter still engaged will destroy the starter.) (BT, DT, GTTS - again)

Sounds like you're that much closer! I have to say I'm very impressed with your abilities and progress on this project, especially since you're not from a mechanical background. This is the kind of thing that many of my friends can't do, and most of my friends are just like me, except focusing on specific manufacturers and design features.
