I have a 92 mazda mx3. I have no power to fuel pump or no fire on engine. So far I have changed the fuel pump. {It works when jumped off of diagnostics connector}. I changed Distrubuter, timing belt, crank sensor, PCM, and all relays and cleaned all the grounds. I have no fuel, spark, fuel gauge, or tack. All lights, blinkers, heater, sun roof works fine.
Do U know pin locations on pcm.
Also I have a GS portalac Battery looking thingy iun the hatch back any idea what this is for.

Thank You Very Much

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
