Check for 12v before and after the relay.

All pins mate ??

Well if you have 12v at the switch side of the relay, then the ECU feed is ok (or switched live it might be on the 20XE?)
If you have 12v before the relay but not after on the fuel pump feed, the relay is duff
If you have 12v before and after but not at the pump then you have a broken wire between relay and pump

Ok ill try that what colour are the wires for that
