if I start my truck on a cold morning something electrical starts jumping on and off and what ever it is it draws a lot power, it kill gauges lights, transmission won't shift. once it warms up a little it's fine, that's why I think it's something in the glowplugs. I've changed the glowplug module and alternator. I'm not sure if the module needed to be programmed or anything but the truck acted the same way. I can plug the truck up and it starts fine
it does show #4 and #5 glowplug circuit open I don't know if that would have anything to do with it, #4 has been that way for awhile. Thanks for any help
