No voltage at tank lift pump

[KevinTW]

could be.........
ign switch,
fuse,
impact switch triggered,
double fuel relay behind ECU,
ecu itself,
bulk head connection under windscreen wiper motor to cabin,
connectors to the right of the centre console above passenger feet,
connectors at the pump,
pump itself,
any of the cableing in between,

that should give you something to start on

Is the 12 volt feed from the battery via a switch a bad idea? Assuming the new relay is ok if there is still no power at the pump can I run a new feed straight from the relay and if so which wire do I splice into?

Anybody know where the impact switch is, what it looks like and whether I can bypass it.
