Has anyone had trouble with these 4 codes showing up all at once? Just replaced HG and am thinking that it is glow plug related. The codes continue to reset themselves until the coolant temp reaches 100F. The service manual doesn't seem to list these code numbers...

P1260 - glow plug #1 control circuit open
P1261 - glow plug #1 control circuit low
P1262 - glow plug #2 control circuit open
P1263 - glow plug #2 control circuit low
P1264 - glow plug #3 control circuit open
P1265 - glow plug #3 control circuit low
P1266 - glow plug #4 control circuit open
P1267 - glow plug #4 control circuit low

Not sure what control circuit low means but you definitely have a glow plug issue. If I was going to suggest something I'd suggest going back over all your glow plug connections.

I don't have anything on P0000

Thanks. I do remember the alternator hot wire arcing once or twice. I am wondering if I messed up the glow plug control box in doing that. I only had the ground unhooked on the battery while working on the vehicle....I am sure I will figure it out this week...

simple fix, I forgot to plug in the four wire connector for the glow plugs that is located near the intake and ACV. Now we know which codes light up when this occurs:)
