hi. i have a y reg 2.0 dti wich was hard to start in the morning.it would turn the engine over for a while then eventualy fire up,once started it would be fine all day but leaving it overnight would result in the same problem.the problem was the fuel leak off pipes which run from the fuell pump to each injector,they were perished and let air into the system.turning the engine over in the morning forced the air out. replacing these cured the problem. they are very easy to do.buy a lengh of pipe from a vauxhall dealer take each old pipe from the injector cut it to lengh with the new pipe then replace it.
