Hi there i have seviced my 06 tdci mondeo zetec and now noticed that it was starting to take longer to start in the morning so i thought it was the battery but no it still struggled to start even after new battery.I did notice that there was some black smoke when driving but today it would not start at all.any thoughts super techs.i spent alot of money getting it back on the road as it was damaged and dont want to spend loads more.many thanks michael

it could be a stuck open egr valve, remove and clean the valve and see if things improve.

ok mate will check this thanks.

checked egr valve and cleaned still the pig would not start but after i jumped it from other car it fired up.took it for a drive still smokie thought i heard a little rattle from engine this is new.when driving it still feels plenty of power.when it would not start the eng/mang/light was on and then flashing glow plug.the egr valve seamed free. but dont know if the valve is meant to be fully open or in closed postion when i checked it as i can push the valve up ?.any help much app,michael.

Update as usual mondeo would not start so checked out the forum and some people suggested that either the camshaft sensor or the crankshaft sensor so today i changed both and car is still struggling to start.anybody got any other ideas i have pulled out the rest of my hair out.many thanks now baldy michael.
