id probly start out checking the glow plugs,each one shoul be about 2 ohms.theres a few write ups on it here if you use the search option.if you do end up needing to replace them do a compression check while you have them out,should be around around 350-400 psi compression.if you get all that squared away and still have a problem you could have a bad injector.
