2005 5.9 auto crank no start

Yikes Don! I hope she recovers.

My insurance agent (the guy that owns this truck) says "If you have a problem that can be solved by money, you don't really have a problem". I suppose he's right. It'll be 4k by the time I'm done with it!

To bring closure to this thread, replaced injectors, rail, CP3, filters. Cleaned tank and flushed lines, running great now. I will also add this. I got parts from Todd at TC diesel and everything was great with the exception of the injector lines. They didn't have part numbers on them and no country of origin....hmmm. Tried to install them and all they did was booger up the threads on the rail and leak terribly. Reinstalled the OE lines and no leaks or fitment problems. I suggest that if any of you folks need injector lines in the future to be very wary of anything that isn't marked with a part number or country of origin. Todd is making everything right and was great to deal with. TC diesel is a stand-up shop and I'll definitely do business with them in the future. Thanks for the help that everyone offered.

I ended up having more problems after about 150 miles of running. The truck quit like you turned off the key. I still had fuel from the lift pump but no rail pressure, zero while cranking. Pulled the CP3 and tested it with some clean oil like Todd recommended and it bench tested fine and shot oil across the shop. It wouldn't pump fuel on the truck! I reinstalled the pump and torqued the nut to 77 ft lbs......still no fuel when cranking. Talked to Todd and he really thought I had a problem in the truck somewhere else but had awesome pressure and volume all the way up to the CP3 inlet. Talked to another friend that has more HPCR experience than myself and he said he has seen more than one slip the pump gear while driving they will shut off. What the heck? I torqued it to about 95 ft lbs and bang, she fired almost immediately. Now the weird part......

It ran terribly and had a P0606 internal processor failure code. I called Todd again (by now I'm sure he was getting really tired of me calling for help) and he said not to worry. Pull the injector lines and loosen and retighten each connector tube to the injectors and it will fix the problem. I did it and it fired up immediately and ran great. It's been running well now for 3 weeks and has had no other problems.

Anyone care to take a stab as to why the P0606 code decided to pop up because the connector tubes??? They were originally torqued to 37 ft lbs and retorqued to 37. The problem went away so I can only think one or two of the injector bodies were in a bind causing some sort of electrical gremlins to show up.

I meant we torque them to 42 now as 37vis known to be not sufficient.

I did mine to 42 a couple years ago and never had a problem.

That not strictly true that way I read the info. 37 ft lbs is still the recommended TQ on NEW old style 5.9 cross over tubes, 42 ft lbs is the recommended TQ on the new style 6.7 tubes. 42 on the old style tubes is an unofficial SWAG when re-using TQ tubes to account for the initial crush and heat cycles.

All things being equal, 37 ft lbs is fine on the old style NEW tubes as long as it is accurate.
