vectra 1.9cdti non-start

[bridge_eee]

hi guys got a vectra 2006 1.9cdti 150bhp
engine just spins over will not start. showed it a spray of easy start and fires up straight away runs fine no issues, left engine off for 3hours came back and started fine when left over night or for long period will not start has anyone else had this issue. i cant seem to hear the lift pump at tank but why would it fire in a matter of seconds when easy start being sprayed in if it has no fuel.
many thanks
