Thanks Dennis.

I wondered if an injector(s) was leaking down. I did the fuel pressure
tests with engine up to operating temperature. If the engine is off
and has cooled about 1/2 down, can this cause a marginal injector to
leak down?

I made a fuel pump relay bypass switch for the fuel pump relay. The
engine had been sitting at least 45 minutes but the engine bay still
felt warm. When I flipped the bypass switch I could hear fuel rush
into the hose, regulator, rail then pressure up. Engine started ok.
