mack engine problem

[edvencher]

New member,haven't read through the archives yet,but could anyone help me with a problem I've got?Someone told me about an old army truck on a hill,that was no longer used by a logger...long story short a month later it was sitting in my yard,wrecked,no brakes,the usual.My brother and I got it started,a cargo mack with a 673 ,but no fuel will come out of one of the injector hoses.I want to take the nozzle and big nut looking thing off the injector pump,but sombody said not to mess with the pumps,any suggestions.Im not sure the truck is worth having the pump rebuilt,can I take the side plate off and see what might have the line blocked.It works well on 5 cyls.Thanks in advance...

There are some manuals available on Ebay from time to time for the Mack ENDT.

But you should give up and sell it to me!!
