NO ECM POWER
GENERAL
A relay controlled by the engine stop switch supplies power to
the ECM. The relay requires a ground to operate. If the
ground is not established, the ECM will not receive power. If
the ECM does not appear to be receiving power, check the
ground sources. A blown ignition fuse or ECM fuse can also
disable the ECM.
