i put in the new batt in this morning and it started then stalled again....and then i couldnt get it started once again.

theres what looks to be a vacuum pump on the front of the engine and it has a pulley for the belt..i just noticed that the belt wasnt on there so the pump wasnt running...would this affect my engine as far as starting it or keeping it running?

Definitely! Get a belt for that. I've heard AIR is far more important for diesels than gas.

*shrugs* It's in front of you, not us.  Quit posting and get it running! ;)

The "shotgun" approach rarely ever works.

Crank-yes, no
fuel-yes, no
spark (glow-plug) yes, no

I used to have friends like that Irish, there might be more truth to it than you think.

Gold, if you have to, step back and give it a break.  To me, it sounds like something simple, staring you in the face, you're just not seeing it.
Do you have a Chilton's?  IIRC, the small one for the 73-87 trucks didn't have much on the 6.2, but the big hardcover (I think it covered all makes) had more on the diesel.  (my brain might be fuzzy,  I haven't had my big Chiltons book since the 90's  :-\)

check here, maybe you can find some tips. (I actually think the link was posted earlier in this thread) [url]http://www.dieselplace.com/forum/index.php[url]

I was considering an oil burner for myself, but now I dunno...

yes i have a haynes techbook that tells just about everything for the gm 5.7,6.2, and 6.5 diesel along with some ford diesels....really the only thing its helped me with is changing the water pump(did that yesterday) and bleeding the fuel system

Cycle the glow plugs two times before trying to start it. If it doesn't start spray wd40 in the intake. Not a ton of it just enough to ensure you are getting fuel. If it fires you know you have a fuel delivery issue.

And no do not use ether or starting fluid as it ignites way to easily for a diesel engine and you could do some serious engine damage.

WD40 yes
Starting fluid/Ether NEVER!

can you crack open one of the injection lines going to the head and see if you are getting fuel there?
