Ford f-350 diesel 2006 6.0 wont start
Hello, I operated a Ford diesel through Michigan Winters. There are usually issues with the Glowplug Timer or the Power Relay to it. If not that, then you probably have a bleeddown issue in the fuel system.
If you trace the wires off the Glowplugs, it will lead to the Glowplug Timer and then the next part is the Glowplug Power Relay. If you take off one Glowplug wire and put the Hot lead of a Voltmeter or test light on the wire and ground the other testing device terminal you can test it.
Just place the testing device where you can see it or have a helper observe it. Then try a normal startup. The test equipment should show that power is going through the wire. The power should pulse a few times and then stop. If you have NO power at that point, you need to follow the wiring I mentioned earlier and find out where the power stops. That part should be the bad part. You want to restore power to the Glowplugs.
If the wires to the Glowplugs have power, there is the remote possibility the Glowplugs are burned out. To test them yourself, they can be removed and connected to jumper cables and briefly energized. The Glowplugs that stay dark are bad.
The fuel system is another matter. First try a new fuel filter to replace a water clogged filter. It is also beneficial to find that fuel is in the fuel filter and that it is not dry. If the fuel filter is dry, then you most likely are bleeding off your fuel overnight. This will require testing the fuel line by using either a Vacuum tester or air compressor and removing and plugging one line end. The line should not leak.
Diesels absolutely require the Glowplugs to work and they work shorter periods in hot temperatures. You just have the pulses to heat up the Glowplugs. So if the Glowplugs are weak, it will show up in hot weather too.
As for the Injection pump, there are Electric solenoids in some which sometimes respond to a "tap" to get them going again. This will mean pump repair to finally repair it. A Diesel shop can also measure output pressure, which , I want to say can be 1300PSI. Beyond the capability of an Owner to do himself.
I hope this helps you and I would be very interested to know what you found.
