I thing g- signal is a rpm or cam signal from distributor to the ECM. Either an input or acknowledgement signal to the computer.

Good evening,

The ECM is not seeing a signal from the distributor for engine RPM. When this happens, the ECM will not allow spark or fuel.

You need a new distributor.

What usually happens is oil gets inside the distributor and the parts inside short out.
