Exclamation Starting and Glow Plug Issue

My glow plug light will only come on for a second and then will turn back off, and now that its cold out the truck is struggling to start. What is going on and what do I need to do to fix this?

OK, the LLY if it has a stock cal, will monitor each glow plug individually. Hook us a scan tool and see if you have a bunch of glow plug codes. If so, repair as necessary. My LBZ just spit out a glow plug out of the blue. I replaced the plug and my problem was fixed. So make sure the Check Engine Light comes on when you turn the key on, if not, that is a good place to start. Then look for codes. These engines are pretty good about telling on themselves. My armchair guess is you need a set of glow plugs, but diagnose them first. Don't throw $160 worth of glow plugs at the engine for the hell of it.

Might be a fuel problem-- the glow plugs on my LLY cycle fast. Also the LLY does not have as much problem with glow plugs as the LBZ. If you don't have any glow plug codes, I doubt that is your problem.

Try pumping the primer on the filter housing, see if that helps it start.

What is your definition of "cold"? Temps please?

Did you actually scan for codes or is the check engine light just not coming on? I have 2 bad glow plugs and it throws a code every time but it does not set the check engine light. I looked at my factory tune in efi live and its not even set to throw the light for bad glow plugs..but it still will store the codes.

OP, you need to scan your ECM for codes before we can help you further.
