Doc - It is definetely blue smoke and not white, FP is fine now but this was originally an issue when I bought the truck. Hard starting is not a problem yet.
Thanks for all the input folks, I kinda new this problem would show. I bought the truck in oct of 06, put a fuel guage on it and it had about 9 psi at idle and you could pull it down to 0 very easily when you drove it, that's why I put the new fuel system on it. I guess it's time to shell out some $$$. thanks again Scott |
I wouldn't buy a new Injector Pump yet. Next question is where is your Pressure guage hooked in at. Before or after your fuel filter.
I would also recommend changing the Fuel Pressure Regulator on the VP44. This is nothing more then the Banjo Bolt for the fuel return line on your Injector Pump. It has a spring loaded shut off in it that is designed to keep the internal pressure of the pump at 14psi. If this spring is weak it will let fuel flow right through the bypass in the pump and back to the tank not sending anough to the injectors. This would also cause your smoke. This is a $14 part from the dealer that you should replace when you install a new pump anyway. So you got nothing to lose by trying it. In talkin to a local Bosch rebuilder here, they told me they have received a good many cores through the years that worked just fine, this bolt was just bad. So they spend $1000 plus instead of $15 to fix their truck. Takes 10 minutes to change out. |

wow, more good info - thanks guys, I'm gonna try resetting the apps and also check into the fuel return on the IP.
FYI - the fuel pressure guage is tapped into the fuel canister any other insight - let me know thanks Scott |

very good point, something else I will check. If I remember corectly, I put the FP guage into the test port which is before the filter - I will definetely be checking this out also - thanks

Well, I put up some big numbers tonight
P0216 I pulled the codes and shed a tear:booo: This would explain my problems!!! I double checked my FP guage setup - the guage is after the filter. I remembered changing it after I put the "big line" from the fuel filter to the vp44 since it had a port on it. Thanks for all the help guys, I do appreciate it, and hopefully these post with all this info will be helpful for someone else Next: Anybody know the best deal on a VP-44? Does a new vp-44 come with a new regulator or should I also purchase one of those? Thanks again Scott |
Better luck next time. A few places will send the regulator with it but not many.
