Ever perform a compression test? This should always be the first step, an engine is no more than a glorified air pump. Plus you have a baseline spec further down the road.
What's the fuel pressure in psi?

I dont consume oil so I feel a compression test would be irelevent and a fuel pressure test would be a good idea...

Let's say for yuks your camshaft has a couple of wiped lobes, hence dead cylinders. Kinda silly to do anything else prior to fixing that.
