Good enough readings to pursue other things to some extent. I would tackle the fuel system to make sure it is not draining back when off for quite a time. A test might be to have someone pumping the primer pump and keep pumping it when you try to start the engine cold.

Of course the person pumping should mention that the pressure to pump is increasing before you try to light it off. If it is much easier to start then recondition the lift pump and generally check the fuel system. There are valves in the lift pump to prevent back flow of fuel for example that may be leaky. Of course if no increase in the effort to prime with the finger pump the relief valve on the injection pump is not working well or perhaps the primer pump is marginal or fuel is being partially fed back through the lift pump.

What you want to be sure of is that the moment you start cranking that there is adequate fuel spraying. Not some form of delay causing inadequate fuel or little at all at that time. Actually cheap to examine this area as well.
