rangerover wont start

hi i have a 2003 l322 4.4 m62 range rover ,it cranks there is a good spark the fuel rail has a good pressure only fault code is camshaft position sensor bank2 which i bought 2 new sensors fitted still same code i cleaned the earth lead to body charged battery up cranks good no start ,the car was running ok went to the end of my road then she staled has not started since .I have looked for damaged wires checked connectors for corrosion tried every thing i know ? not a hint of starting it seem the injectors are not putting any fuel into the cylinders ?any body got thoughts thank you

Have you rechecked the error codes since replacing the cam sensor?

hi yes i cleared the fault code but it popped back up

Can you swap with Bank 1 and see if the problem moves?

hi i swaped the sensors cleard the fault,it still came back with same code P0348 i sprayed easy start down manifold cranked over still didn't fire up there was a small back fire though the manifold i am starting to lean towards some mechanical problem

What is the code?
If it's a sensor open or short circuit, then it's the sensor or wiring.
However if the code is a cam timing or sequence error, then that would point to cam drive failure.
However a simple compression test would tell you that for definite, but often you can hear a cam timing issue, simple by cranking the engine, as it doesn't sound right.
