6.5 is surging and bucking

Thanks alot! I read your post there. There's some responses coming in now, I got a few things to check there. THanks!
 
Well, replaced the pump, and the injectors while I was at it, problem solved.

But, man, that's hard on the 'ole wallet.

Ouch!! I know your IP is a bit more computerized than the older mechanical ones...but I paid $347 for my IP and 8 injectors to be rebuilt through Accurate Diesel back in 2003.

At least it's fixed now....:crazy:

Wow 16 hours to R&R the pump and 10 Hours for the injectors:eek1: damm that seems a little high. But at least it works now:crazy:

Well, I'm slow. I've never done this before, worked on a diesel, well not to this extent anyway, so I was going especially slow and making sure I was doing everything the way the service manual outlined. I power washed and cleaned the whole engine very good before I started, took my time, and I think it paid off. It's runs really well, started first key turn, idles smooth.

I could have found other rebuilt IP's for 400-500, but they don't replace everything in them and most aren't warrantied in that price range. Usde IP's were going anywhere rom $200-$400.
There's lots of places with 600-700 rebuilds, but none close where I could go in person, they are like eBay places or online diesel shops, so you don't really know what your getting and good luck trying to warranty it. The place I got my pump from was a Stanadyne authorzied place, and this particular pump was rebuilt by Stanadyne itself, tested 3 hours on their stand, all new internals, all new electronics, including PMD. 1 year warranty, including labor (standard mechanics rate at GM book for hours ,I think 6 or 7 for my K2500 pickup)

The injectors are brand new OEM Bosch injectors, not rebuilds. Since I got 200,000mi on the first set of OEM Bosch's, I figured they must be pretty good so I stuck with those. Lot's of guys run the Delphis, which usally run $70-80 cheaper for a set, but they are fairly new for the 6.2/6.5, and longevity has yet to be proven from what I can see. Kit came with 1 year warranty, braided return hose, new injector gaskets and a couple bottles of stanadyne diesel treatment, and exceprts from the GM service manual on how to replace the injectors.

Truck runs very smooth, throttle feel is 100% better, idles perfect, runs strong through the whole RPM range, I can shift it normal again, gone is the touchy jerky throttle feeling. It's quieter too.

Hopefully, I'll be good for another 200,000mi! Well, at least that was my thinking with the [hopefully] quality parts I bought here.

Looks like you took the correct route. $1200 isn't bad if somebody else did the work. You could easily pay $800+ for the parts alone. Looks like you got good parts as well.

Go ahead and get a remote PMD mount. You can install it yourself. It's been stressed as a very important upgrade.
