Definitely worth a shot, but I belive the fuel pump to be on the same circuit as the ECU just after the DME relay. It has been my understanding to listen to the fuel pump as it will tell you if your getting power to the ECU/DME

The only thing throwing me off is that his fuel pump is still running, which is on the same side of the DME relay as the air mass sensor.
Will a DME relay fail in a closed condition tripping up the airmass signal (due to continuity) while keeping the fuel pump running? Then work again for a few weeks 2 minutes later?
