With a paper clip, or solid copper core wire in or out of the A and B terminals, key on in correct position the check gauge light just stays lit steady, and battery light also, no connection or flashes for codes.... 95 truck works correct though with connections, flashes etc...When you turn the key on, engine off, does your SES light flash on/off once, then come on steady until you start the engine? If it does, the light bulb is good AND the ECM is working. Now we need to figure out what's wrong with your ALDL connector and wiring...
If I had to guess, something's wrong with your O2 sensor and when it goes into Closed Loop. Without a scanner, it'll be hard to diagnose
