How possible can all 8 glow plugs be bad? I've ohmed them at harness plugs and get no readings. Good 12vdc to and from GPCM. New GPCM. I ohmed them as read in other threads with two different meters
No relay or solenoid like a 7.3. Just a ccontrol module. The cm is newRelay maybe..
Sounds like another issue?????I changed them all in my 7.3 today thinking I had several bad ones.. every one of them checked less than 1 ohm.. most were .7 ohms...
I changed them because it wouldn't start last night when I went to leave work, and even used the jump pack to the glow plug side of the relay.. nuthin'..
ended up having to ether it to life..
no. I have good 12vdc pwr to and from gpcmYa I should have said GPCM.. Any fuses blown?

Should just pop off with a flathead screw driver.
They very rarely pop off easy. Spray them with some PB blaster Around each plug and wiggle it around to help loosen it. The best tool to use is a door panel trim tool that fits around the sides of the harness plugs. Theres a tool made just for glow plug harnesses from OTC that fits around the plugs with a hook on the end to pry them out. Remove the passenger side fender liner to access the rear plugs.
Really? Mine came right off..guess I just got lucky then.
