RE: Lift pump, relay, and fuse
Thanks Rawze, that is where I was looking for the fuse and also where I found the relay. So I searched and searched, found no fuse on the Volvo side.. looking back over the wiring diagram on QuickServe I saw the ECM controls the ground pin on the relay pin 85, and return signal is pin 86.. so I tested again for power on pin 30 with the other lead of my tester on the chassis.. and I have battery voltage. I have ordered the pump..

It appears Volvo did not use a fused link to the pump relay, at least not in that location as other OEM’s have. At any rate the failing pump didn’t blow the circuit.. so I should be good to go with the new pump when it gets here..
