Very sound advice, thanks! Fuel in tank and pump runs to prime fuel system pressure. The MAF sensor part is Bosch 0-261-230-057 and is located in the swirl manifold. I am presuming that no signal from a crank/cam sensor would deliver a subsequent fault code; it could however explain why the motor will not fire! Fuel + spark = GO until the electronics get inputs. I am now wondering what the ECU read when starting.
