Hi Nick.

Nick has a T series turbo.

I have connected the
green and yellow marlin wire to yellow rover wire.
green marlin from ignition to white which becaomes green and pink

Although the power goes to the relays it does not come back down the green and yellow wire when the key is turned.

Ok things to check. Turn on ignition and check for 12V on the green wire. Should also get 12V on the Green/Pink at both the ECU connector and fuel pump relay.

If this is ok, it could be that the ECU is doing it's normal job. It just primes for 3 seconds until it knows engine is cranking. For testing purposes, connect the Black/Purple from the replay to Earth (instead of the ECU doing it.) If all is well, with the ignition on, you should read 12V at the Green/Yellow wire. Also check you have 12V on the Brown/Grey wire. This should be live even without the ignition.
