Help! No start

Got error code u106 lost communication with glow plug module. Has anyone had this problem before? I also think my batteries are dead. I have a 2012 lml deleted, no egr cooler intake and a mbrp 5 inch straight pipe. I am running an h & s mini max 100hp tune. The truck started and like 15 seconds after starting it died and wouldn’t start again. I open the primer screw a little and it had fuel coming out so I don’t think it’s fuel. The batteries are old and I will test in the morning. And then I guess I will buy a new glow plug module. And advice. I have an air dog 150 lift pump that I haven’t installed yet.

All bets are off if your batteries aren't good. test/charge/make sure your batteries are good and fully charged, then see how your truck works.

So I charged the batteries all night and then had them tested. They were bad. I bought new ones and installed them now I’m getting a p2510 trouble code. Something about power switch to ecm relay.

Installed new batteries and retuned the truck with the H&S and Magically it started and runs fine I guess when the batteries on these trucks go out it is a bigger deal than I thought.

Were they the original batteries, or is there something else going on that's killing them?
