A bit of easy start but as soon as it’s knocked off will not start without it ?
Crank and cam sensor’s been changed no codes no lights on dash
Anyone help ?

Try leak back test, or get diagnosed also maybe look at the HPFP regulator O-rings.

Running well after starting
Is it just taking air in the hp ?

I don't have a TD4 but reading the threads on here, if it is the regulator O rings on the HP pump, they are cheap and quite easy to replace.

You don't have to remove the pump, just slide the regulator out (which does necessitate removing something else I believe, but not a major job).

Its fixed lots of sick TD4s.

Yes remove the starter motor which will also give you chance to check the connectors inside any car that has done 75,000 or more will benefit from having the starter connectors replaced another easy job with starter motor off the car.

regulator is two torx and it will come off the car link below for O-rings.
