I've got battery positive voltage at the source terminal of the relay under the back seat that I think is for the fuel pump. Another terminal (the one from K40?) is ignition switched positive. The drain terminal is 0.6V above the battery ground, shouldn't it be 0.0V to ground?

Jumping source to drain gets no fuel pump noise, no fuel pressure, and no spark at the jumper wire. I think either my pump motor has failed, my pump isn't grounded, or the wire between relay and pump is open. Car and probably fuel pump has 247kmi on it.
Is there an easy way to get power to the pump itself?
