yup, the fuel pump has a resistor to slow it up, then the relay short circuits the resistor when the car decides it wants the full pressure..... and, yes, its switched earth (which makes the electronics easier, but can do your head in when sorting thru many logic gates 
)
quite common for people to just short the resistor connector when their fuel pump is getting tired
so the alternator rebuild is a separate issue?
have you monitored the supply voltage across the relay?
