Well at 49,000 miles started having delayed starts when cranking, kept getting worse of course. Changed both fuel filters at 50,000 miles ( drive 100 miles a day ) Almost corrected starts to normal then after about 500 miles its back and become worse as time goes on. Now if it is cold it will take a while to start, if it is hot ( operating temp ) you might as well not be in a hurry to get it started. No SES, runs great once started, does not make oil, does not smoke. Run B2 from local retail place, Total Power, and have ran some Killem just in case. After some PM's with Eric and I concure that I may be suffering from too much return flow from the injectors and / or injection pump has went south. I have appt with dealer Thursday morning a scan and diag session, sure wish I had my own Tech 2 for times like these, sure wish I could afford to buy one.

Truck is 2003 2500 D/A 51,980 miles in stock form so we shall see how the well the GM Gods smile on me.

Will keep informed.

Truck is in the shop today, Did get to talk to the tech this morning and with the Tech II connected saw that the fuel rail pressure was low and start up, of course it was starting easier for him this morning. The fuel rail pressure dropped real fast after engine shut down.

Just called and talked to the service advisor and he talked to the tech and it is really being difficult, we first thought that it might just be a issue with the fuel regulator. He now thinks it could very possibly be a set of injectors :ro)
for me.

Just got off the phone with my service advisor. I am getting a set of injectors, sure am glad they are under the 100,000 mile warrenty. Would not want to have to be going to the credit Union to arrange a loan to pay for this.

So at what milage did you install your secondary filtratrion?
