any one had a cold starting problem with a 2.2 cdti omega,once started its no problem ,but if its left for any length of time back to square one, so far ive replaced the battery ,glow plugs ,all spill pipes ,fuel filter ,injector seals ,removed and cleaned inlet manifold and throttle housing finally fitted a non return valve between the filter and injection pump ,it seems to have the symtoms of fuel run back as in it has to be wound up for a mega long time before it will start. help! ps it seems to be worse the colder it gets

i have a 51 plate 2.2dti and it has the same problems,
dont matter how you park it even nose down on a hill, seems like fuel is returning to tank and a right git to start, i start the car everyday even if i dont intend on using it and this seems to help a bit,
is there a how to on cleaning the filter in the tank?
im guesing the panel under the carpet in the boot gives you acces to it?
if you find the problem please post it as its been driving me mad for ages! Wink
