I’m having a hard time finding the fuel pump relay also. Where is the external fuel pump at and also where can I check to see if I’m getting power to the fuel pump also there’s a fuel filter in the left side engine bay that has a hose disconnected feeding out where would that hose go to.

 

On the 6 cylinder cars, the oxygen sensor heater relay also affects fuel pump operation, i.e. if faulty or removed, fuel pump will not run. Don't know if that helps?

 

I have posted the electrical manual here: https://www.jaguarforums.com/forum/x...4/#post2590112
Page 9 has the relay locations.
