Is there anyone in the Pittsburgh that has a scanner that can check for codes for me? After Friday I will be replacing my fuel pump and the O rings in the fuel bowl. I am getting some blue smoke on start up. I don't know if the engine is starving for fuel since I was stuck in the tunnel a few weeks ago.

If you don't have any luck in Pittsburgh - I'm near Akron and will be getting an Aeroforce scanner this week. If its worth a 2hr. roadtrip (assuming your truck is running at the moment), feel free to swing by.
Just curious, as I have several different types of scan tools, but how do you expect a scanner to help with a fuelling issue?
Just asking, not being a smart ash.
By your thread title I thought it was one of those "HELP im on a road trip and need help in order to get home" type of deals.
If you want to use the scanner to get some readouts like pressure for fuel or whatnot you can just get some readings with a tire gauge?
Although if you have codes and just want to read them then yes AE would help.
When I placed the tire pressure gauge on the valve I got < 15 lbs of pressure. By replacng the fuel pump, hoses and O rings, plus cleaning the fuel screens I hope to remedy most of the problems. I need to find out if I have some bad injectors or not.

If you have <15 PSI of fuel pressure you need to remedy that issue first, then worry about anything else after the fact. With fuel pressure that low, you are just chasing your tail until you address that issue first.
blue smoke on start up could be a few things. possibly injector O rings. possibly valve stem seals. neither would be something that throws a code. when you had the filter can open was the fuel in there clean? or dark with motor oil contamination? im thinking orings. is there a CEL? orings arent too hard to do if you follow the instructions. not an expensive repair either. i agree with the others who say fix your fuel pressure problems first. and use a real fuel injection pressure gauge. theyre not real expensive. if your fuel pump is kaput do yourself a favor and search fuel pump replacement on these forums. you want to make sure to not drop parts into the motor.
I'm about 2 hours north with an AE, but as others have stated unless your are throwing codes I don't see it being much help. Fixing the low fuel pressure is a definate start, you can buzz test the injectors but if you are feeling a flow issue they really need to be pulled/tested/ upgraded by jim..hahahaha
Yesterday I replaced the O rings on the fuel bowl. The 2 screens looked like charcoal. I cleaned them thoroughly. The fuel bowl is ready to be-installed after I remove and replace the fuel pump. The banjo bolt is removed and the fuel pump is loose. The next thing is to turn the engine by hand to make the piston on the FP is on the upper part of the cam lobe. Tomorrow I should get the pump out and the new one in.

Before you install the new pump run the banjo bolt in and out a few times to clean up any burrs on the threads. It's bad enough to get it started but if there are any rough spots left from when it was machined it just makes it worse.
Today I finally finished the replacement of the fuel pump and rebuilding the fuel bowl. I ended up making 1 wrench and bending another. To get the front washer on the banjo bolt I used a thin piece of thread to hold it while I pushed the banjo bolt through the pipe. It worked fine. The only problem was that the clamp that goes on the turbo side broke. I took it to a friends shop and he welded another piece of a clamp to it. Then I buttoned everything up. I poured some fresh fuel into the bowl and poured some fuel on the filter gasket and fired it up. It started right up without any problems. thanks guys for your suggestions. Sam Miller's article was a real help as well as the folks at Diesel Orings.
