Hi, first post so hopefully someone can help. My 2008 C4 pic 1.6 hdi isn't starting (turning but not firing). Did fire a couple of times using easy start, so suspecting fuel pump or electrical supply to it as there is no diesel reaching the filter with ign on.
I'm trying to check voltage at pump connector block on top of tank before dropping the tank to renew if required, but can't ascertain which wire is 12v +/- powering the pump (there's 7 wires in the connector block including sender wires) and can't find a colour code/guide elsewhere on the forum.
Does anyone know what wires in the connector block come from the fuel pump relay?....really appreciate any help.
