p0671 - bus bar removal tool question
I'm throwing a P0671 (Cyl 1 glow plug circuit) and white smoking like crazy on cold-soak starts until it gets warmed up. My guess is the GP is dead and cyl 1 isn't lighting up right away, so my smoke is probably unburnt fuel.
I do have the 03 solid bus bar. Do I need any special removal tool for that? It seems like the special tool is only needed for the post-04 GP wire harness.
I will Ohm test it to make sure it is the GP and not something else, but I figure I'll buy the new plug awhile and replace it anyway. It's a cheap enough part. I know the dealer replaced 2 bad ones last summer on their dime from two different cylinders and they also replaced the bus bar, so it should still be in good shape.
