VP fuel pump issue

[rubaduckee]

hi guys, I have a problem with my fuel system, when I turn on the key to accessory, the fuel pump is not turning on to pressurise the system, have checked the fuse and relay.

my fuel system is as follows:

I have my stock in tank fuel pump going into a bosch 044 fuel pump etc, the bosch o44 is powered of the rear mounted batery through a fuse then into a relay with the original in tank pump wired in as the switch.

now as I have said, I have checked the factory fuse, and relay and they both work fine, and for the relay going to the 044, the power from the batery is fine but no current coming from the in tank switch line.

ps, the car has been running and driving until yesterday afternoon when I jumped in and this happened.

Maybe the pump is dead?

If that were the case, wouldnt the other still wind up tho?
