Hi
I have a huge data base of files on the Cherokee and yes Cherokee the GreatLakes site has proved a great source. I have found no earlier than 1999 in pdf or cd format that covers the VM. Lots of info for Gilda though of petrol engines
However do not dispair, I have found a seprate file that may help.
Click here for the link
VM Diesel, don't panic it is in english; although on a Russian site. I am not sure if it was lifted from a complete file.
Hope this helps.
Just as passing thought if the fix you have does not work, check your water sedometer, drain it and change it if you have not done, or do not know when it was last done. I have known this to stop a diesel. I suspect it is most likely a electrical fault as already suggested, such as a fuel injection pump it self.
