From what I can make out, the middle wire is for the pump immobiliser. That shows batt voltage when the immobiliser led is off but can't detect any current being drawn from that. The other wire comes live only when the middle (immobiliser) wire is live. With the ign switched on that wire shows around 10v (not full batt voltage) and the current seems to be bouncing around at very low mA's. I thought I'd see what happens if I connect a wire direct from the +batt onto this wire abd when I switch on ign it gives an initial current draw of about 20mA before droping back down bouncing around the very low mA's. Fuel sucking into the pump but still nothing coming out. Will try get hold of a longer easy out tool for the 2 sheer bolts and see if I can get at the solenoid. Can this be got at without undoing any pipes or removing the pump?
