"Grounding a connector" means you join a connector in a circuit to another point in the circuit that is definitely at ground potential. This is done mainly when testing a circuit, to be sure that a particular point in that circuit really is at ground potential if you are not certain that it is already. Alternatively, you could be doing a test to temporarily ground a connector that is not normally at ground potential, to see what effect doing the test has on the behavior of the circuit.
An ammeter is a amp meter put into a circuit in series. There is virtually no voltage drop or resistance in an ammeter so two in series would be redundant. If you have one in a circuit it will tell you the amps that circuit is generating, two would both give virtually the same result.
Protective devices - relays, CT,PT, isolators, circuit breakers are used for fault protection. Fault protection means If there is a fault in the circuit, the circuit must be cut off before any damage occurs due to fault.
A GFCI can not be used on a three wire branch circuit. It has to be on a single two wire circuit.

A: a ground on an IC is just a reference to the lowest point of voltage that can be applied.

If you mean a bare copper wire, that is the "ground" wire.
i believe you mean lamps a bulb is what you plant in the ground.
The ground in an electric circuit is the brown copper wire.

Ground fault relays sense ground faults in the circuit and trigger a circuit breaker to trip off

There could be a short to ground circuit . The fuel pump control circuit may also be sticking open which would also cause this fault.
Short to ground or overload in the circuit.Short to ground or overload in the circuit.
