Does anybody know where it is?
I need to crank the engine over without it starting and figured this would be the easiest way however I've no idea where the relay is!
Anyone?
Thanks.

What year is the car? 
I used to be indecisive, now I'm not so sure!
I used to ride on two wheels, but now I need all four!

The e-HDI doesn't have an electric fuel pump. If you don't want it to start, unplug the injectors, or the crank sensor.

Thanks, probably why I can't find it then!!RichardW wrote: 31 Jan 2026, 13:57 The e-HDI doesn't have an electric fuel pump. If you don't want it to start, unplug the injectors, or the crank sensor.
I was thinking about unplugging the injectors but won't that spray fuel on cranking?

I think Richard meant unplugging the electric feed to the injectors, not the fuel feed!

Bump!
OK, so I've managed to unplug the connectors for all injectors and managed to test cylinder 4 and 3 however 1 and 2 are not possible without disconnecting the fuel filter lines because of the access needed resulting in diesel spraying out on cranking !
Any ideas on this?

Finally managed to test all the cylinders without spraying fuel ! 3 coming back around 410 and one is showing 400 so guessing all OK.
