Default New guy with problem

Hi all,
Just replaced all my glow plugs on my 2006 2500HD and still get the engine light and error message telling me the #1 cyl glow plug was bad. I know the glow plug is good so where do I go now? Engine has 133000 miles on it

Moved to LBZ section of hard parts. Double check all your wiring. What # code specifically was it?

"The Cruzer" -- 2014 Chevy Cruze Diesel -- the fun little DD
"Kleshay" -- 2000 C5 Corvette -- the toy
"The Bigger Boat" -- 2011 Workhorse P700 - 6.0LS/Allison - what I drive at work

Two wrongs dont make a right, but three rights do make a left.

Reality is a matter of perspective.

This forum isn't for the weak of heart.....or wallet.

If you are 100% sure you have a good glow plug (as in, you checked continuity and verified it is good), then you either have a connection problem or a bad module.
