It will crank and rumble like it is gonna turn over but never will. It will just rumble and blow white smoke out. Any suggestions or advice?
Check your glowplug relay with a volt meter. Another thing is glowplugs themselves being bad. You can check the glowplugs by removing them and using a multi meter and check the resistance of the glowplugs.
What is your location?
