SOLVED: Fuel Pump Permanently On
My apologies for the delayed response to all the very useful messages and information that you guys posted. I feel at home here already and I really appreciate it. I've had some drama's so wasn't in the state of mind for internet stuff, back on track now :-).
After speaking to 2 garages and one friend who is an eletrcial engineer and a great source of auto knowledge and coming up with no definitive answer I decided to take the plunge and simply replace the K40 relay or whatever name you wish to use for it, seems to differ :-) This seemed to be the recommended course of action.
The fuel pump issue was instantly resolved, it now turns off as soon as the car is turned off, even left it stood over the weekend as I was on the beer and on Monday it fired up no problem so doesn't appear to be any drain at all on battery.
K40 has only been replaced a week now but the intermittent cutting out and and more intermittent failing to start (not even turn over) also seems to have stopped, I will post updates regarding this issue over the next few weeks as only driving it will let me know for sure.
Strangely, or not if you know more about cars than I do, the car is running beautifully, far smoother and responsive than prior to the K40 module being replaced. It is NOT my imagination lol.
I purchased the part online and the guy even through in all the plugs and wires so I cold replace the one that someone had butchered, so far a great result all round.
Interestingly, one of the plugs he sent me that I did NOT need has 2 wires coming from it while my original, and as far as I thought, untouched plug, only has one wire so I now have a spare wire coming from the central black plug on the K40. Everything works on the car as far as I can see so what is it for?
Any idea to what the stray wire should connect to? I'll try post an image or make one available.
If this works its the wire on the right, its red and green.

Any feed back would really be appreciated and certainly put my mind at rest, maybe :-)

Thanks in advance
