2000 f 350 won't start

Hi did you check the glow plugs if not get a small piece of wire plus 12 volt bulb connect it to the wire that connected to the glow plugs turn ignition on and see if it lights if not check the fuses plus the cold start relay after that you can fit a piece of wire from the battery to the glow plugs then try to start it. best of luck let me know how you get on

There is also a glow plug control module. This my be the issue.. The other thing is and this has to happen with all diesel's, Replace your fuel filter every 12 months or 20,000 miles

check engine immobiliser and crank position sensor . Run fault codes and replace faulty units.

Check and make sure your glow plug controller is putting out voltage to your glow plugs, make sure voltage to your glow plugs is cycling. if it is not, at the front of the engine there is a temperature switch, if this switch is not working your glow plug controller will not work. also make sure you are getting diesel to your injector pump, if you are not, there is a high pressure switch at the back of the engine right behind the glow plug controller, if this switch is not working, your injector pump will not get fuel. also make sure both batteries are fulley charged, if one is low, your diesel will never start. you can jump out these switches, if your truck starts after bypassing, just make sure to replace them. i have a 1993 silverado C3500HD 2WD. good luck!

Have you checked the glowplug relay.

your glows plugs not working. check glow plug relay or fuse.

Check the glow plug thermo sensor...found in the cylinder head.
Unlightly anything wrong with injector pump.
Good luck

Yes, my 2003 did the same with about 75k miles on it, stranded me on days it stayed under 40F unless I plugged in the block heater the night before, then it started like a champ. Dealer replaced the relay and a control unit under ESP warranty. There's no way to fix this one without throwing parts at it.

disconnect your glow plug relay and try it, the relay may be shorted out
