How to test glow plugs?
hey my truck is throwing a p0380 code... which means a bad glow plug or controller. how is the best way i can test for this? when i fire it up and its cold (like 50* or colder) i have one of my cylinders that has quite a bit higher injector balance rate, but once it warms up, its just like all the others. Is that a sign that possibly my cylinder #1 glow plug is the bad one? or what is the best way to test to see which one(s) need replaced?

as you said, p0380 usually indicates 1 or more bad glow plugs, g/p controller, or the 175 amp fuse. check the glowplugs first. take the rail off of them and get a test light, hook it to the pos side of the battery and touch the tip of each glowplug. if it lights up the glowplug is bad.
