Hi, my 2002 2l diesel estate c5 has not been able to start 3 times. Mechanics cant find fault because by time I tow to garage its started to work again. No fault codes, good continuity of cable from relay to elec pump, fuel pump relay is clicking, fuse is good.

Any ideas?

How did you check the fuel pump relay ? It's an internal part of the under bonnet fusebox.

Just guessing I suppose because I can hear a click when turn key which sounds like a relay functioning. Have got the car going now by rigging cable from battery straight to elec fuel pump. Taken cable away and works every time now but need to sort it for good.

check the 16 pin grey connector on the under bonnet fusebox, this is where the fuel pump feed comes out, the pins can over heat & cause connection problems. have a look at the pins on the fusebox carefully & check to see if any of them have a blue coloured coating (cant remember the pin no off hand), clean the pin & re fit & see if it works then.
