There are testing procedures for relays and ohm readings but it differs for all makes. The easiest way is to swap out an identical relay on the vehicle and check to see if the pump comes on. I know that on Ford Rangers there are 3 that are the same ECC, fuel pump, and AC. Since I knew that the ac worked I moved the relay over to the fuel pump and got no response still, so I moved it over to the ECC and both it and the fuel pump worked so that told me that the ecc relay was bad and it in turn triggered the fuel pump relay to activate in series.
