I have a laguna 1999 dti diesel.
having trouble starting. New starter fitted new battery. New glow plugs. But will not start first thing in morning turns over fails to fire. If I do get it to start it runs fine all day no problems at all. But then the following day wont start again. Somtimes starts after 3 attempts and somtimes drains the battery. Without attempting to fire.
Compression combustion engines are sometimes sensitive to contaminated fuel or the wrong fuel, #2 light diesel can sometimes vary a great deal. When I worked on diesel motors with my dad, the fuel issue was the first thing he taught me to look at when hard starting was the complaint. Cetane ratings should be at the manufacturers minimum rating. Fuel filters should be changed on a regular basis.
