What is your question?
My 2006 Liberty has 111000 miles and has been very well maintained. Yesterday the engine began knocking. I pulled over, checked all the obvious issues and found nothing. After about 30 minutes it started again. Today, I was doing 50 mph when I heard the knocking again. This time I began losing power and eventually the Jeep died. I towed it to my office. Here's the weird thing. When I try to start it, the starter engages, the serpentine belt starts turning but the engine is not trying to start. The starter was changed about a month ago as was the battery. I have people telling me it's the timing chain, but I have one guy who's done work for me before telling me it's the MAP sensor. I really don't know what to do next. I pulled the MAP sensor and will buy a new one tomorrow and try that, but after that I'm stumped. Any ideas?

First is it a 2006-2.8 diesel engine like you posted?? Next a map sensor is not going to cause your engine to start knocking! Best have a 'mechanic' take a look!
Sorry. It is not a diesel engine. I was banging out the original post on my Iphone and I must have fat fingered it.And maybe "knocking" isn't quite accurate. It was more of a rattle and it wasn't terribly loud. I had a guy that works on some of my other vehicles look at it and he suggested that it was the timing sensor. When I pulled that sensor off the engine I found that it was called the MAP sensor. Everyone else who has checked it out tells me it's the timing chain. I own a trucking company and I work with quite a few amateur mechanics.
Back to the shop , your wasting money buying those parts , Knockings a bad engine anyways , or bad injectors , injector, Tow it to a shops...
All I've done thus far is pull out the MAP sensor. I haven't bought the first part yet.
You not only need to get this to a shop and have it looked at, it needs to be someone who works on these diesels a lot. Unless you have a specialist near you, your best choice might be the dealer.
Do they make a diesel in a liberty..?? I rather be strokin than jeepins Doesnt sound rite..
Yea and they are not fun to work on. The learning curve is a 500ft cliff.
