93 dakota wont start

This may be bad news for you.
41= An open or shorted condition detected in the generator field control circuit.***
*** generator lamp illuminated
From my FSM for the 95. Chap 8B IDK how close this is to the 93.
This section covers generator service procedures
only. For generator or charging system diagnosis, refer
to Group 8A - Battery/Starting/Charging Systems
Diagnostics.
The generator is belt-driven by the engine. All engines
use serpentine drive. The generator is serviced
only as a complete assembly. If the generator fails for
any reason, the entire assembly must be replaced.
Three generator output ratings are available on
this vehicle, depending upon optional equipment. Be
certain that the replacement generator has the same
output rating as the original unit. Refer to Group 8A
- Battery/Starting/Charging Systems Diagnostics and
see Specifications.
The generator field control (voltage regulator) circuitry
is internal to the Powertrain Control Module
(PCM). If faulty, the entire PCM must be replaced.
Refer to Group 14 - Fuel System for PCM service
procedure.
I have no idea how to test the PCM. It is possible the generator/alternator is bad but IDK. There is a 95 FSM on the FAQ page.

Actually, that Code 41 is suggestive.
Time to triple check the WIRING at that side of the motor; it sounds like it's disturbed, and it could be keeping the ECU from being able to fire the motor. Could even be disconnected at the back of the motor (the engine/body harness plug), causing no injector and no fire; although I'd expect more errors than just a 41.
Also, if it is a failure, you don't HAVE to replace the ECU. That's easy enough to bypass with an external regulator; there's scads of write ups, YouTube videos, and even kits to do that all over the Internet.
