That is a hard one to figure! Looking at a wiring diagram shows where the wires run, but little else. Pump cycles normally to maintain 43psi, the only component that would control the pump is the ECM, if the fuse is blown the relay won't work. Try switching the relays as they will interchange. Just an FYI, from what I understand ECM failures are rare.
