I dont know if im in the right place but I need help she throws codes P0672 and P0676. Its for glow plug control circuit on cyl 6 and 2. The glow plug light comes on when its cold and wont go off and its hard to start. Also if its sets a week it drains the batterys so I have to jump it dont know if thats related to the first problem yet or not. Any help would be nice thanks.

i have read that the glow plug relay go's bad along with one or more glw plgs ... that could be draining your batts.

Same thing happened to me minus the batteries going dead, my truck does not usually sit for a week. The Glow Plug Control Module was replaced as well as all 4 drivers side plugs.

Thanks I'll take it in and see what I can find out.

check your local dealer for recall on the glow plug controler. i have a 06 lly cclb drw and i got a recall on mine 8 months ago. plus they changed all eight plugs
