Van won’t rev!!!

[kindasquirrelly]

Hello,
I checked the injection pump timing, when it showed 0.97mm lift it was three teeth out on the flywheel gear. I reset the timing by loosening of the cam rear sprocket as advised. She ticks over a little more smoothly and a little less smoke but still no revs increase.
I checked it three times to be sure.
I intend to put an electric pump in prior to the banjo on the inlet side to see if it is the primary pump is performing badly.
Any advice welcome.
Regards
Michael

That's quite a bit, actually. IP throttle shaft back to factory original position?

Now let's see what the smoke can tell us. What color, how much, when?

Make sure it's a low pressure pump. More than 3-5 PSI can start blowing the seals out of the IP. Why not put it before the fuel filter, so as to protect the IP from any fuel pump-introduced debris?
