ramdom wire on c20let

[torquey]

I've got a random wire which is red/blue on my c20let loom where it goes through the bulkhead. It looks as if has been snipped wondering if its causing my fuel pump to run consatant as iam having problems with it?

Red/blue is fuel pump, the pump should only turn on cranking.

Yeh I know but it ain't soon as I connect the battery up its on found what the wire is its the lamba sensor its been snipped the red/blue one would this effect it anyway where do I need to join it back in I not the best with wiring sorry

The fuel pump should take its switched live from the fuel pump relay, you are looking for a dead wire at the fuel pump relay that goes live on cranking only. This wire goes to the relay.

The lambda has three wires on it, two white and One black. The two white ones are heating and can go either way round. The black one is the one thats the key one as it controls the closed loop.(closed loop makes it use less petrol and run leaner when warm. I'll see if I can find the colour codes of the car loom so you know which ones to connect to which.
