Vauxhall Vivaro starting problems

I have a Vivaro 1.9 55 plate diesel. 3 weeks ago it had a reconditioned gear box and new clutch. One week ago it developed a problem starting, it fires up straight away, runs for approx 10 seconds then stops. I can only start it again with easy start, whilst it is turning over I can hear a clicking sound on the right hand side of the engine compartment which stops when it runs on its own. After its firt start it will run perfectly and start as many times as necessary all day until the next morning. Can anyone help ?!!

Its sucking in air into the diesel fuel line while stopped overnight. Keep away from easy start and bleed the system before you try for a start.

Look for leaking diesel joints while the engine is running.
