Ok guys I have a 2000cummins and it was running great till today I started up a grade in 598th gear no issue till half way up it started stumbling only at 1800 rpm and up while in the throttle so I turned around and took it home and got the car and did my running well after I returned home I started it back up and it stumbled for a few min at idle and cleared up till I raved it to 3000rpm and it started stumbling and blue smoking and right befor I let off it poped in the exhaust. It also has 14 psi fuel pressure and no cel what could be causing this?

Did it crank over for longer than normal after it had been sitting for a while?

No it did not it fire right away no issue

Any injector leaks or high pressure fuel lines spraying? 

Odd issue.  I'm thinking fuel or injector system issue. 

you ought to check for trouble codes. Not all codes will set the cel.

No fuel leaks externally I'm going to read the codes as soon as I can get one or get it to. Auto zone I'm sort afraid to drive it at this moment as I currently do not have any funds for a tow if What ever it is goes completely out. I there any way to tell if this is injector or vp related with out the codes I can not afford to throw parts at it as I just had to put a nv5600 in it a month ago

I would say it a air in the fuel. Some where you have a suction air leak into the system. The high rev misfire and the bluish smoke is most likely air.

Thanks for the replys after work to day I got a little time to check a few things I checked for oil in the coolant and coolant in the oil none present also checked for blow by none is excessive. Checked for airaited fuel and fuel volume and all that is with in spec. Don't believe I have a air leak due to the fact it always starts first turn over 

All the more reason to check the trouble codes. Not sure where you live but you can usually get a scanner for a deposit and the auto parts store and bring it home if you dont want to drive the truck.

Yes but I think I'll just buy one So that I have it for future times. Also besides checking codes I believe I'll go ahead and do a full service with all new filters I didn't realise last service I didn't put a fuel or air filter in it and this could be my issue

Lack of fuel or air or both will cause some issues.

Yes that's y I'm starting with new filters and reading codes to eliminate the simplefirst how ever if that dont work and there's no codes where would y'all go from there?

If its not sucking air in somewhere, lift pump(what kind do you have?) or VP, kind of hard to say. Check the codes and lets go from there. Mine has stumbled like that before with a dirty fuel filter. Changed it and it was gone. 

No air in the system I Know that. I'm getting a scanner Friday so I'll be able to report back on that then. I am sadly running a airtec lift pump wanted a Cass but what I had save want in to the tranny a couple months ago but it holds 14psi at idle and 12 at woo throttle I ensure that with a gauge and low pressure light how ever due to past fuel pressur losses I hope the vp didn't did

While the fuel pressure is not terrible it could be better, but I understand financial limitations. Bare in mind that most low fuel pressure lights do not come on until about 5 psi or less, well into the danger zone and could just sit a 6 or more for along time before the light comes on. let us know what you find with the scanner.

I will let y'all know and he's the past losses concern me I didn have the gauge then 

Ok guys got my reader and it only had the dreaded p0216 injection timing code so I recon ima have to put a vp on it

That doesn't sound good.

No it doent considering I am broke after the trans but I believe I'm going to stick the new fuel filter in and clear the code and drive it to see if it comes back

If you don't use any 2 cycle oil in your fuel try it 1 oz to gallon, make sure it's ashless. And in your case try a bit thicker mix, might get some more life out of it until you save some money for new vp. Industrial Injection is the one I would go with, don'rt waste money on anything special. 

The 2 cycle oil is a good suggestion. Super tech from wall mart fits the bill. The 216 code is not death as some describe, but is just a matter of time. Who knows when. Where do you hale from Steven?
