Fails to start after sitting all night. Once primed with easy start fires up no problem and will start all day long. Glow plugs and glow plug relay changed.

Common cause with most is it drawing air somewhere from a hose connection or a pinhole or fuel running back into tank . You could try switching ignition on 2 or 3 times prior to starting and see if that primes the system .
