Hi Gang, I just replaced my injectors and glow plugs on gen 1 6 liter in September and it was running and starting great. Now it will not start and I discovered there wasn't continuity to glow plugs 1, 5, & 7. When I re-installed the glow plug harness in Sept, I squirted di-electric grease into each of the cups and everything checked out. I am perplexed why these harness's fail but I would think it would be the cup end, but that is a guess? Has anyone pulled one of these 'hard line' harnesses apart and fixed the issues why they fail? I ordered replacements but in a time crunch and curious if I could place some tin foil in the cup connection on the glow plug? Also, can I cut off the hard housing and make the lines flexible? I need to get this rig working so I can get back on the road. Or am I missing something else totally? I use the Torque App and will get a misfire code when trying to start it and all the other critical pieces appear to fine - like FICM power, HPOP psi, and so on. Plus my fuel pump appears good and the fuel is treated. The only way my rig starts is if I plug it in for 2 plus hours and it is cold here in NW Wyoming. Curious what others have to say?
