I finally had a few minutes and started to change out the glow plugs this afternoon. I quickly realized that I had all the tools I needed.........at my parents home. So I started into it anyway and as I removed the first one it did not look bad at all except for a thin coat of black almost crystalline like substance at the tip. I changed it out and promptly dropped the nut for the power lead and down it went. Looked and looked etc. finally sprayed some brake cleaner in the area that it fell and then shot some compressed air as well
( after placing a large SS catch tray under the car and ping there it fell.
I placed the lead on and tightened everything down. by now I saw it was going to take longer than expected without the proper tools so I started putting my tools away. When done I thought I would go ahead and see if it had affected the non functioning dashpod GP timer light. As I turned the key it flashed on and quickly went out. I tried again but no go. I pulled the key and did it again and bang the light came on and promptly went out. Anyway I will change the remaining plugs Monday and see what happens. The GP's get power and the timer gets power and you can hear the relay click and it has a brand new correct battery ( another thread). The only issue is no GP light and having to cycle the GP's 4-5 times when the temp drops below 69 degrees or so. I will update.
