This issue was evident before bridging the eccs plug. So I suspect a driver (or FET as you said) is dead from the relay failing. As a work around could I take a 12v ignition live from pin 31 into a relay and ground pin 4 that way?

Sorry let me start again! Pin 4 is 12v with ignition on or off If I then ground pin 4 with ignition on using a power probe I get 13.5v on pin 67/72

-Pin 31 has 12v when ignition is on -Pin 4 is ground ignition on or off -Only seeing 9v to pin 67 & 72 Disconnecting the relay and bridging the pins gets me 14v on 67 and 72 Thanks again for the guidance

Sorry my bad, it's a GTT link

Hi guys, Hope you can help. R32 gtst, spec 2 RB25 on a G4+ pnp ECCS relay had failed, causing fuel pump to stay on with key turned to ignition and ECU looses power when cranking. Tried a new relay, same issue. Removing the relay entirely gives the same symptoms as it being plugged in, even wiring in a 40a 4pin relay does the same. The only way around is to bridge the pins on the relay (3 to 5, 6 to 7 and 1 to 2). Then everything works as it should, fuel pump works when cranking and running, issue being now that the ECU has permanent power. Do I have a further issue with a relay elsewhere, or is it a wiring/ecu problem. The car had been running for a few years before this, so nothing has changed recently other than the car being in a minor crash and then it got repaired/painted. Appreciate any advice! Thanks
