Xud9 White smoke and primer wont stay hard

[ekjdm14]

Would hope it's sorted by now, but my money would be on the vane pump being sticky hence not making transfer pressure (= retarded timing) and not sucking fuel for itself (= it's just running off what you prime into it and never fully clearing of air). Never had an issue before but this time round (XUD9TE into 'plexed petrol 206) I ended up both the pump on the engine & a spare I had both were gummed up, and even after rebuilding once I had to go back in because it still wasn't quite free enough to make transfer pressure.

I'm blaming it on veg for my pump being gummed as I left it sat a couple of years with straight sunflower in it & it turned to polymer, but the one on the engine originally I'm calling as foul modern diesel.
