So far have replaced, high pressure pump & in fuel tank pump filter. It starts first go now every day. If left for a day it's much better than before. But when left 3 days or more, the problem is back, but does start quicker than before with old pump. So dropping pressure over 3 days. A friend thinks could be an injector seal, leaking fuel back into tank. I'll have to pick the brains of someone who might know a bit more about these injectors to see if that's true.

Any luck?
