E39 530d not starting

[Mark]

Have you checked the inline pump? Give the passenger floor a hard thump from inside the cabin just in front of the passenger seat, I used to have this issue!

If you can get under it, tap this fuel pump while trying to start it. Once you have it running, if the car feels like its hitting a rev limiter at 2200rpm or so then it's definitely this pump

Its back running, changed the pressure switch on the pump and it done the job!
Thanks for the help
