So the past few weeks my car turns on with the key just to accessories but the glow plug light and the check engine light don't come on and the car won't turn on (still turns over), but it doesn't seem to have any issues later in the day (usually starting it at 5am for work).

 I'm not too sure where to go from here I've checked fuses and changed the diesel filter as I wasn't sure if anything was clogged in that. Just wondering if this is a common issue and an easy fix that I'm missing, cheers.
