No start (no fuel?) V70-XC70 2003

Hi all, I went to start the volvo yesterday and though it cranks, it won't start (not even a putt-putt). Eventually the immobilizer kicks in. The day before it was fine with no issues at all. Things I tried so far:

1- fuel pump fuse good
2- checked the shrader valve by the injectors and no gas came out.
3- fuel pump relay (I tried slowly pulling in and out of socket and it clicks repeatedly while ignition is on. With it pulled out I tested and have voltage across both relay's circuits (a little less than 12 volts though)
For normal operation, should I be getting voltage from both circuits through the relay? I heard some fuel pump relays on other cars do the opposite- they open the circuit?

I'm wondering if it's a sensor/ECU issue? I only mention this because I have in the past had intermittent p0014 camshaft sensor issues but not for quite sometime. The me7 Motronic; does it require this sensor to allow the pump to work or would that instead be the CRANK shaft sensor?

I'm seriously hoping it's just not my pump, as I hear it's not cheap to replace and find it a little odd that there were no noticeable warning signs like loss of power etc.

If anyone has any suggestion of things I can look for before I get it towed to my mechanic.

Thanks.

    The 2003 has a fuel pump control module, is that what you refer to as a relay? If the pump module fails, it will store an error code. If the fuel pump itself fails, there is no error code - just like running out of gas.

    I have found that fuel pumps seldom fail while the car is running down the road. You were lucky that it failed at home and not many miles away.

    Yes, the pumps are a pain to replace, but much better than the 1998-2000 models which called for dropping the rear subframe and tank or cutting holes in the body.

      Thanks KlausC. Actually I was referring to the relay under the hood. Is there an easy way to inspect the pump and this control module you mention? Maybe a loose or corroded connection is causing this. I don't have any error codes.

      Yes I was thinking how lucky it failed at home and not on the road somewhere, or even during driving. That would be scary.

      Thanks.

        The old style 'fuel relay' is no more after 2001 or so. The fuel pump 'module' is next to the gas tank, exposed to the elements in 2003. The V70 has but one pump, the XC70 has two because of the saddle tank system.
