My LBZ is throwing P0671, P0673, P0675, P0677, and P0679. Since these codes are all on one side, I have trouble believing all the glow plugs are bad. I don't have the truck near me to test the plugs with a multimeter right now but I'm thinking they'll test ok. So whats left: wiring, GPCM? Anyone else have this happen to them?

GPCM I would say... Each GP has its own output from the GPCM so I would say you have a slim chance of shorting out only those wires.
