Ok. So. I snugged the 8mm nuts on all the glow plugs. Removed the fuse and reseated it. Removed the power lead to the relay to see if it looked like there was a problem with it. There doesn't seem to be. The soldering and the clamp seem tight and the wire is still good. Plus I'm getting 12V thru that power lead. I checked the Ohms' in plug number 1 which was giving me 67 yesterday. It was giving me 58 this time but when I tried the resistance at the actual glowplug itself it also gave me 58 Ohms. So is it a bad glowplug? or a problem in the plug harness itself? Or should I just spring for a new relay and see what happens?
