Guys need some help.
Some of you might remember the issue I had with the car not starting hours before my mot. I diagnosed a faulty ecu fitted replacement car started, tried old one back in car started so I think I have an issue with the wiring to the ecu.
Currently car won't start with either ecu, I managed to hook up laptop to prove crank sensor and have also proved spark. I've test at the fuel pump and there is no feed. The workshop manual said that the fuel pump relay is negatively switch via pin 3 on the ecu plag an I have found this its a grey with black strip wire.
But the issue is that the relay I have been looking at doesn't have a grey and black wire going to so I think that is not the fuel pump relay.
Has anyone come across the fuel pump relay and where it might be? The 4 relays in the engine bay i have checked it should be one of these.
