84 blazer 6.2 diesel
 

I bought an 84 blazer with the 6.2 diesel motor. The guy I got it from started pulling stuff apart not knowing what he was doing. I got the truck back to turning over but it won't start. I can't find any books or diagrams on this motor and I m anything but a diesel mechanic. If anyone knows where I can find anything on this truck or have anything you can send me please respond.

Have a look here for mechanical info,for diagnosis you would likely do best posting specific problems and what you have done here and get help that way:

You need to determine if fuel is getting to the IP. then you need to determine if fuel is getting to the injs. Older 6.2s with a Mech lift pump can be a bitch to get started if the fuel system has been opened.
