My truck has been throwing a glow plug code and i got some new plugs and went to change them. I soaked them down in some wd 40 to loosen them up a bit. and broke 2 off the num 1 and 8 so I gotta get them out. but with new plugs it still dont wanna crank. It will spin over for a good 15 to 30 sec then wanna hit off what else do i need to do
LB7: glow plugs

Since you say it's an LB7, I'm guessing the code is a P0380. If this is a federal emissions truck, then the P0380 means either that all 8 glow plugs are out or the glow plug controller is bad. Need to know if it's a federal truck or cali emissions truck(cali truck has 8 individual wires hooking each glow plug individually where a fed truck has a rail hooking each side together).
See if your getting power to the glow plugs on the passenger side. With federal trucks the rails rust out and it shuts all the plugs but #8 off.
I'm getting the p0380 code also and mine is the Cali emissions, I am getting power to all the plugs but I'm still throwing the p0380 code so it could possibly be the control Module? It wouldn't surprise me because when I got it back together I had the wire from the alternator running to the single stud on the control module like a idiot.
