Better?
Are you hearing the fuel pump run when you first turn on the ignition ?Well, I've made some progress.
Finally got the plug off the EDC, there's a little sliding lock on the bottom of the body plug that releases it (thanks, DaveB). Cut back all the heat-resistant shielding and silver tape (thought it was gaffa at first, but I think it's more like the heat-resistant tape heating engineers use). Anyhoo, no chafing or wire damage visible, although where the cables enter the plug does look a little suspect. Liberal spray of contact cleaner in the plug and socket to de-grease it and reassembled. Did the Forscan again and no different, still showing P1665 (although the other 6 or 7 faults it was reporting are now all cleared).
So then I followed some advice I found on the Transit forum which was written to troubleshoot this kind of problem. I found continuity between all relevant pins within the two plugs shown. By this stage I was starting to lose hope and getting more resigned to the fact that at least the EDC may be dead, maybe the whole pump. Just as a final check I tested for shorts between the pins in the EDC plug and there is one! Pins 3 & 6 are shorted, which means pin 3 is shorting to earth. As the advice said no shorts should exist I'm a little encouraged by this. And as this fault is showing with the pump and EDC disconnected I'm further encouraged to hope the pump and/or EDC are not faulty.
So, I need to find where that short is and rectify it, and I'll start by trying to clean up the cable entry into the plug as it doesn't look too great. Failing that I'm at a bit of a loss really.
I can't say I've ever noticed it.Are you hearing the fuel pump run when you first turn on the ignition ?
Unless it's a high horse power one, it won't have an electric lift pump.I can't say I've ever noticed it.
