My buddy's got a 1996 chevy 2500 with the 6.5 liter and all it will do is crank and not turn over. we have changed the glow plugs, fuel filter, plugged it in for a full day and all it still does is crank and thats it now there is smoke coming back through the intake tube after trying to start it. I need help bad we need to get this thing running.

 

Pump driver, look up the ICE driver for the 6.5.

 

where can i go about looking something like that up is that the black computer box looking thing that says fsd or fuel solenoid driver

 

Yep, it has been years since I played with one, you should have a code showing.

 

well then whats the easiest way to check a code on that truck

 

I believe with the 96 you need a scanner.

Probably best to hit one of the Chevy specific forums, dieselpage or dieselstop, don't remember which.
