Truck was left in a parking lot while I went in for a doctor app. When I came back out there was a large dent in driver door. I admit I was close to the truck next to me but this was the only spot left and they were over the line into the spot were I was parking. Really aggravating but I guess some people are just jerks! Anyway long story short the truck started missing a few days later, could really tell it at idle and now starting to detect it at speed. When I went to fuel up about five days after the door incident I discovered the fuel cap was off. Pulled the tank last night and what was left in tank doesn't look good, extremely cloudy and smells like gas, also some brown liquid floating around. I have been working on diesel engines a number of years but this is my first time with a common rail system. From what I have been reading I know I will be replacing all the injectors. I am wondering about the injection pump and rail also. They may be all right for now, but I am concerned about potential failure down the road from whatever has been through them. Any thoughts and all advice will be greatly appreciated! I know this isn't going to be cheap!
