Hey, so about a month ago my clutch rod broke on my clutch master cylinder on my 6.5. Long story short I didn't fix it right and it sat until I got it towed to a shop last week and the day I got it towed I went out and brushed the snow off and reconnected my batteries. and ever since I got the truck when I go to start it and I turn the key on there would be a pretty loud sound that I assumed was the glow plugs because it would come on when I turned the key and would go off when my glow plug light turned off. but when I went to reconnect my batteries I turned the key and my glow plug light came on like normal and went off after a normal amount of time but there was no loud sound with them but I could hear them click off when the light went away which concerned me so I didn't try starting it. but I looked it up and apparently glow plugs don't make a sound so I didn't really know what to think. and the shop got the clutch fixed and squared away but when they went to test drive it they said it was running rough and stumbling and I've kinda hit a brick wall because this is my first truck and I know nothing about diesels. after looking up if glow plugs make sound google said the sound I'm hearing is the "fuel injection control module" and when I looked that up for a 6.5 all that came up was PMD's so I'm thinking my PMD went out and I have another in my truck so tomorrow in going to the shop and gonna swap it out in the parking lot but I just wanted to know what the more knowledgeable people thought. could it actually be my PMD?
