Hi guys ive been trying to read all over I'm new to the duramax forum and new to duramax/diesel trucks. I havnt had any issues with my truck just the other morning I went to start it and nothing. I put the key in let the glow plugs do their thing then when I attempted to turn the truck over I got nothing not even a click. batteries are good. all power/gauges are working when I do turn the key to start position then let go all the gauges reset... ive looked into the nsbu switch but I still see my prnd321 and I still see the indicator line underneath.. any answers could help thanks!!
