Fuel Pump relay

Hey folks,

I have an 85 4000 quattro that isn't starting.  The fuel pump wasn't coming on, 
so I shorted the fuel pump relay circuit and the pump started ticking and making 
all kinds of noise.  From what I'm told the relay also controls the cold-air 
fuel injection primer, so I'm not sure that shorting the circuit will mean the 
car will start.

I'm having trouble finding a known good, so my question is:  Since the fuel pump 
wasn't making any noise and presumably not coming on, does shorting the circuit 
causing the pump to make noise mean the relay is bad?
