At the risk of sounding stupid, is it one of them models you need to tell the system it’s had a new battery and ‘code’ it in?

Hey all, little update, I went to a LR garage today as I was passing and chatted to a technician. Really nice guy, he seemed to think the likelihood of it being ECU related was unlikely, he said in his experience it’s usually the fuel pump that’s next to the fuel tank behind a little inspection panel. he printed a diagram off for me, have attached to this post. Has also given me a test to do to confirm his prediction (pull out a hose from the fuel filter, then the Ignition on but don’t start the car and see how much fuel comes out) … let’s see if this revelation takes me anywhere

Hey sorry for the late response… hmmm, I wonder??… will look into it; thanks!
Had that go on mine and a slight wake up call from a small hammer got it going enough to get me to the local indi garage who fortunately had one in stock along with a spare ramp for me to chuck it on.Hey all, little update, I went to a LR garage today as I was passing and chatted to a technician.

Was it easy to get to? My RR is currently in lowered suspension mode which makes getting under it a little more tricky.
It was easy for me cos I was using a 4 post lift but unless you're very very skinny I doubt you'd get under it. Maybe jacking it up and using axle stands is an option.

No way I would rely on the air suspension when going under the car.

Right. Update… the pump is def working , so back to square one! Haha

Have you checked the fuel pressure yet?
Fuel pressure regulator is a fairly common fault.
The low pressure system pressure is approx. 1.5 bar to 5 bar and return end < 0.6 bar. The pressure in the high
pressure end is 200 bar to 1350 bar.

I need a proper diag for that right? Or is there another way? Thanks
My Foxwell reads them but no idea about what you are using.
