Having cold start problems 2006 h.d. f350 ,truck is parked in heated garage all night,starts normal in the a.m.,sits outside all day at work,soon as temp falls below 30 F it starts then stalls immediately...
Follow your glowplug wires towards the Firewall. The glowplug wire goes into a Timer which is suppose to be internally regulated by outside Temperature and feedback from the glowplugs.
When you are in Cold weather, the Timer is suppose to keep the glowplugs on longer. When the engine is fully warm and you shut it off, you will notice it starts up like a gas engine. First you want to remove your glowplugs and check them by using Jumper cables and heating them up.
Be careful because they can melt or distort if on too long. I usually pull out 4 at a time because it is a comparison test and when you find the quickest, brightest glowplug you measure the others against it. When the glowplug stays dark or does not heat as quickly it is bad. Remember when it is in the engine the glowplug only has bumps of current coming from the Timer to warm up.
Once you are confident the glowplugs are okay, try starting the truck. Or for good measure, just change the Timer, but it will add to the cost.
As for the engine light, if you mean the "check engine" light, you can get that checked free at Autozone, Oreillys, or Advance. I believe Advance may be better equipped to test the PCM.
I hope my solutions are very helpful to you and thanks for using this service.
