Why not do a simple fuel delivery test? Remove the return line from the
pressure regulator and run a short piece of hose from the regulator
return fitting to a small container. Then run the fuel pump for 30
seconds. You should get 1 pint or 500 ml of fuel, at least. Or if you
run the engine and fuel continuously comes out the return fitting then
you know to look for some other problem.

If the above fuel test passes my guess is that you may have an intake
valve lifter problem, maybe too tight. Time for a compression test to
find which cylinder to loosen the adjuster on.
