New pump came in while I was out of town but I haven't had a chance to get up under there and replace it yet. One additional bit of information is the old pump has a resistance from the positive terminal to the negative (with the power cables disconnected) of 3.0 ohms while the new pump has a resistance of 9 ohms. Based on this I'm guessing something shorted out. So now the current is flowing through the short and the voltage isn't making it to the electric motor in the pump.

Tighed1,

I check the relays and they were operating just as you described (middle three close, fuel relay clicks open after 2 seconds). So that gives me a little more confidence it's just the pump that has gone bad. Once I can get under there and put the new one in I'll check back in and provide an update.
