Right need some help recently removed engine and engine loom only from saph and fitted boa engine and engine loom which has its own main relay however on the old engine loom was a yellow 40mp relay which plugged into the car loom also would this be a main relay? as since the new installation all lights, indicators, horn etc work fine but starter motor which is new just clicks on flywheel and fuel pump does not prime (pump does work as I've tested) I have checked and tested fuel pump relay which works fine and sends a power supply to pump but pump does not prime its as if its not sending enough power, but if I remove the relay and loop the live on to the feed it primes and works fine.
I'm now thinking maybe the relay that was attached to old engine loom was a main relay, it had a live from battery, earth to ecu, feed to main engine plug and switched live from dash multi plug (on interior dash loom)
