Thanks very much for replies/suggestions.

Tony L, The High-pressure pump appears to build the required pressure as rail actual pressure almost follows the desired (as long as I keep priming the system). I hope it is not the injectors as there is no way of locating where the retaining bolts or nuts are as every thing under that top cover looks like it has been in the sea for months.

Trevor, checked both fuel supply and return for restrictions and blanked them and the fuel filter to vac test and all good.

Lee, not one bubble in the fuel pipes so I assume it can’t be the swirl pot problem or it would be full of air after running.

Antony, If the low pressure pump was separate it would be easy to test, but with this I suppose if one can be supplied separate to HP pump then it may be worth a shot. I checked the suction from the low pressure pump whilst cranking to find this increasing to 15inHg Vac after 5 seconds but could this be partly suction from the HP pump, I’ve never actually tested how much an HP pump sucks.

I wish I had never seen this van, now the dash panel has gone blank

Thanks again.

Graham
