Where is the fuel pump relay on a 300tdi?

Glyn D · Jul 26, 2018

Hi guys,

I'm in the middle of wiring up an alarm/immobiliser to my 1996 300tdi Defender 90.

All I've got left to do is add an immobiliser to the fuel pump but I haven't been able to find the relay.

I've tried disconnecting the relay I thought it was, but after 10mins the engine is still running.

Fuel pump relay on a mechanical pump ??

All sorted. Just used the wire that goes to the injector pump

I think you will find the problem with the stop solenoid wiring is if you lie under the car you can reach up and touch the wire and the solenoid itself.
Might be better to find a fuel cut of solenoid to fit in the main feed fuel line?

As said above, you are wasting your time putting a cut off in the wiring to the fuel solenoid.
