fuel injection problems 200 1992

Doesn't seem to me you've missed anything - in the way of easy-swap parts.

In light of the 121, I'd examine the harness connector for the AMM carefully, but that isn't known to flood a car, more like starve it. Could be the ECU has the injectors on all the time - rare, but known to occur. Is your spare compatible? Run the fuel pumps without the motor by jumper 4-6 fuse. Squeeze the return hose briefly to be sure it isn't blocked.

Go through the mode 3 diags on your OBD - make sure the ECU can click the injectors, CS valve if you have one, etc. Make sure you fully reset the ECU - lift fuse 6 for a second, and double check those suspect parts (AMM and FPR) in your swap car. Ox sensor shouldn't get involved in starting problems, but you might want to be sure it isn't shorted to the heater by disconnecting it temporarily, or putting a meter on it.
