Outer Limits 4x4 Board

Hi all,
My 1hz have problem starting when it's cold but it starts first go after i switch it off and start it again, could anyone tell me what the problem could be whether it's injector or fuel pump?? Maybe just glow plugs??

Id start with glow plugs first mate. Depends where u live and how cold it get there. Diesel motors run very inefficient when cold. I'd start with glow plugs and go from there mate.

make sure your getting power to the glow plugs first. they blow fusable links near the battery sometimes.
