94 K2500 6.5 Turbo diesel
 

Hey guys I found a truck w/in 30 miles of me that is a diesel.Has a few things that need fixed and I'm kind of worried about how the guy who owns it installed the PMD himself he also installed a new block heater. What are some common problems or things to look for on the PMD problems? He says it has a u-joint going out on the drive shaft but that isn't to hard to replace I don't think. Well here it is. I offered him $2,000 as is.

Any input would be appreciated.

I like it. :jump::jump::jump:

pmd problems usually start out as a "fishbite" where it seems like its misfiring. sometimes they will just stall. then you can start them right up again. some have also reported that the truck will accerlate at full throttle. sometimes they just stop working. thats the syptoms i have heard of. for 2k it sounds like a nice deal as long there isnt a ton of problems.

He installed the PMD on the firewall so I was told in an e-mail from him.

The best place for the PMD to be installed is out of the engine bay. Perferably right behind the front bumper....

x2 thats where mine is

Its all about general maintenance. Move the pmd like woody said. It will be the cheapest diesel you will ever own parts wise vs other diesels out there. Not to bad looking, u joints arent that bad.

u joints are easy, as soon as i bought mine i replaced and relocated the PMD and its been a great truck, 260k miles and still goin strong, id say as long as its a moderatly clean truck and not too many issues 2 grand isnt that bad

injector pump on 94 6.5.. its been while since i did one on 6.5, hard?

Its not the worst thing to do but you better dedicate at least one full day to it.

need a scanner for this and special pump wrenches

With the injection pump removed the pump driven gear could jam in the front housing by engaging the starter motor, resulting in a sheared crankshaft or camshaft gear key and possible valve train damage. Always bar the engine over by hand to avoid internal damage.

NOTE : Removing the fuel injection pump and injection lines requires removing the intake manifold.
