Thomas, you wont get many replies with a post like that. More info needed i.e. problem with the vehicle,tess carried out etc. If your glow plug light is flashing then one or more of your glow plugs is goosed.These don't come on for starting,unless its very cold, but come on after starting for smoother running and lower emissions control. More info needed for posts, or you will be "shot down" on this forum. HTH
