Alright guys, I literally feel that I have read a million of these threads today searching for the answer to my problems. But almost 90% of those threads have ended with nothing being posted about a positive solution. So if you have any helpful information or tips please share.
Here the story,
I went to install my valve springs and F1 nozzles this weekend. Everything came apart smoothly and no real surprises. Springs installed, Piece of cake. Nozzles installed. Also went well. EVERYTHING was done clean and extra time was taken on the installation to make sure it was correct. I had the help of a very knowledgeable member (DODGE74, who I cant thank enough). So anyone that knows him or his posts know he knows what he is doing. But anyway everything was torqued to spec and then checked and so and so fourth.
So heres the issue. When we fired up the truck, it cranked and cranked for a few seconds but then finally started. It idles ROUGH!. Heavy white smoke at idle. SO we shut it down and checked everything. It all looked good so tried again. This time it fires right up like normal (cranking wise) but still the same results. white smoke and horrible idle. So we start unplugging wires from the injectors to chase down a possible bad one. No real change as each one was unplugged. Nozzles 234 and 5 all appeared to have some carbon built up from firing off, 1 and 6 were clean. As if they werent spraying or spraying entirely too much.
I decided to stop fighting it as it was getting late and pulled them all out and took them to a local diesel injection shop. I was expecting one to be hung open or bad or whatever. 96,000 miles on the bodies so I honestly wasnt surprised. But heres the twist! The shop said they were surprised at how well they flowed and at how balanced and matched they were for as large a nozzle they were. FML right?
So tomorrow I am going to get the injectors and put them back in and see what happens. So... anyone have any ideas? From the threads I have read I have came up with possible culprits causing my issues.
1. The blue clipped injector harness' on the outside of the valve cover could be reversed.
2. Leaky or bad connector tubes ( have a new set to try)
3. Valve cover gasket/harness is bad ( Im taking a multimeter with me)
4. Injection shop is a bunch of crack heads and they actually are bad ( unlikely but who knows)
5. MAP plug could be backwards (checked it but I will double check)
Also, I cant stress how careful we were to keep everything clean. New copper washer were used. Nozzles are brand new Flux 3.3.
As always, thanks for any helpful info or assistance anyone can add.
