Best I can tell the distributor uses an optical pickup, not a magnetic. I pulled the other one apart to see if I could find what was wrong with it, couldn't see anything and turned it in as a core for a remanufactured factory unit, truck still get code .. so it has to be a wire, same for the fuel pump, still getting code for it and had just replaced it along with a new filter.

Does the voltage get reduced to the pump at times like idle or is it full time 12v ?
I'm thinking running my own ignition triggered relay directly to it, I mean it has the Fuel Pressure Regulator.

As for the distributor, I'll start looking and testing wires, but does the wires from the distributor go directly to the ECU ? That way I can color code them and check, bypass if needed.
