our dearly beloved '83 280zx non-turbo has no pulse to the front 3 valves...it's only running on the back 3....and running roughly....

is the brain box the problem???
or could it be a much simpler/cheaper solution???

bury it, it's dead.

Check your injector resistor(s). Your injection system is probably a pulse type which means all injectors are triggered simultaneously. That eliminated the brain.

Check: plugs (for fouling - are they black), injector wires and connectors, compression (in all cylinders).

I agree, check from the injector harness's back toward the ECU through the resistor pack, check all connectors as you go. Also check for shorted injectors in that group.
