Ok - new here so HELLO.

Just picked up an 88 B2 for $250. It was ran out of gas and the t/c was stuck in N.
I checked the gas reserve on the frame and it had gas. I checked the fuel pump on the frame and it had gas. I checked the fuel regulator at first it was damp but then after playing with it, it is now dry.
I have checked the initia switch on the passenger side. It is white and doesnt seem to be engaged or tripped.
I found the relay on the passanger side under hood. I dont know how to test it.
Can someone explain in the simplest of terms how to test the fuel pumps by jumping the relay. ( I hope I am stating that correctly )
