Bought a 2006 Liberty CRD about two years ago. It is my fourth one. In the last two years I have driven it a total of about 150 miles.....the rest of the time it has sat at my shop or at the Chrysler dealership in a nearby town. 120,000 miles when I bought it. Came in on a transport and didn't make it out of the Chrysler dealer parking lot before it quit. Filter head was loose and worn out. replaced it and thought OK......since then I personally, my Chrysler dealership friend (who I went to school with 40 years ago) and the very best diesel mechanic in the county .....have tried repeatedly to find a way to make it run after it warms up. Tried all the fixes. Every sensor, pickup pump, new computer, hoses, turbo waste gates, you name it we have done it....still does the same thing it did the day I bought it......runs pretty good till it warms up then acts as if it is getting way too much fuel or no air and dies. Black smoke so thick that you can't see the car behind you, if it runs well enough that day to move down the road. Knocking, clanking, dying. Used the Chrysler dealership "black box" code reader over and over....everything within parameters. Used the vinyl hose air test on inlet and outlet to the filter head....no air.
I have read post after post everywhere I could find and nothing to explain this. Hoping someone here can give me some info towards a fix.
Didn't pay a lot for it...but have put so much in it now that I can't let it go without losing money and my sanity. First car out of over 200 in my life that simply seems "unfixable".
Just to make sure everyone knows what all we have done.
New ECM
Checked all injectors.
All new sensors, common rail parts and pieces.
New alternator
New battery
New bypass valve on pump
Pickup pump in tank.
Cleaned EGR
Checked turbo, waste gate operation and all vacumn parts.
Someone before me had already installed new fuel line from tank.
Tested every parameter on the code reader and ran all tests.
About a week ago....my Chrysler buddy cleaned the EGR system....ran perfect for about 8 miles. I stopped, it started running rough and I started it about 25 times to make it back the 8 miles to his shop. Motor would rev quickly then die. Drop it in neutral, turn off the key and it would restart to run about 10-15 seconds then rev up and die. Finally though starting over and over and coasting down hills made it back to the first stop light in the town....where it continued to run...very poorly...enough to get in the shop parking lot. Sounded like it was coming completely apart. Same thing it has done over the last two years.
I am no excellent mechanic, but I drove an 88 Kenworth all over the US and kept it going. This little ******* makes no sense.
If anyone has any idea what is going on here...please respond.
thanks
