vectra c 2003 2.2 dti cold start issue

[sjs]

Hi guys, yet another starting issue, recently had injector seals and leak off hoses replaced because if i left my car stood up for more than a couple of days it would nt start(air getting into fuel line) problem seemed be solved and no starting issues, that was untill winter kicked in and the temp dropped right down, now although nowhere near as bad as befor it struggles to start if the temp is between about 10deg c and 2deg, at about 2deg the glow plug light comes on and it starts fine its just the bit between 10deg and the glow plugs kicking in that it struggles, it normally takesvabout 8 turns of the engine to start(that just does nt seem right), anyting below 2deg fine and any thing above 10 is fine, does anyone know at what temp the glow plugs should be active and what activates them? I do have a suspect thermostat that seems to be stuck open, could this be inked to the starting problem? Any help gratfully recieved and may well help stop me going insane!!! Thanks guys

Could try temp sensor on top of thermostat or it could be glowplug relay
