Okay so as a lot of us 7.3 owners most of us have had starting problems. Mine is like the others. So I have a 2002 excursion 7.3 meaning I have the stupid glow plug control module. I had to rebuild my glow plug harness for a few broken wires. Replaced all the glow plugs recently trying to fix my problem had multiple that where trash. Problem still here I also replaced my valve cover gaskets in case the harness was bad plus I had a small leak. So my truck still won't start haven't replaced my glow plug control module yet while I was testing to see if I got power to the connector at the valve cover and while probing the outer 2 wires on each connector I found before pulling my key out of my pocket and getting off the truck I had set the other probe on the battery and found I had a constant 10.2V going to each glow plug all the time. Is this normal or is something up please help. I also need to do injectors soon as I did a buzz test and 4 where weak sounding so please help me guys. I have searched and searched for this and found no info about it being normal or not
