Problem: Explain your problem in concise language (ie: Cranks but won’t fire). Starts and runs fine sometimes. Other times it will run for about 1 1/2 min and then surges/misses and stalls. Stalls while running, but only at low speeds. Runs fine with no missing or surging at 60-70mph. I just put a new CPS on the truck because the code came up and still have problems. It ran fine in the winter, but as soon as it started getting hot out is when the problem started.
Demographics: tell us about your truck and your ambient conditions:
- Year: 1995
- Truck model and class (ie: c2500): K2500
- Automatic or Standard: Automatic
- Mileage: (indicate miles or km): 250,000
- Replaced parts and mods (IP, PMD, chip/PCM, TM, injectors etc): IP, PMD/FSD, Starter, Fuel Filter, CPS.
- Model: ‘S’ or ‘F’ engine, NA or Turbo, EGR?: F Turbo
- Ambient outside temp: (indicate *C or *F): 80-100F
- What fuel are you using? (#1 Diesel, #2 Diesel, Bio, VO, WVO, etc): The kind most gas stations have lol?
- What fuel additives are you using?: I have used some, but I didn't keep the bottle and can't remember the name... used it after the problem thinking I might have clogged injectors, but didn't solve the problem.
- Where are you located?: WV
General maintenance: inspect and evaluate the condition of each. When were they last changed?
- Air filter: I bought the truck for months ago and all I have changed is the CPS and Fuel Filter. I did clean the air filter though recently... was pretty clogged up.
- Fuel filter: Within the last 350miles.
- CDR Valve? _________
- Coolant – last flushed/replaced at _____________
- Oil – synthetic/regular, changed at: Rotella - 600 miles ago and filter.
- Batteries – state of charge, (matched set) replaced at _____________
- Battery cables and grounds (removed, cleaned and tightened): ______________
- Glow Plugs - how many miles on them? _________ What type? _____________
- Injectors - last changed at _______________
History: (Describe how the problem first appeared.)
- What were you doing when it happened?: Driving less then half a mile to get a pack of smokes one day and I stopped at a red let and noticed the engine started to miss. Foolishly ignored it and then when the light turned green I accelrated. Missing was still there.. got about half a block and it started missing bad and surging. Stalled and pulled it to the curb. Tried to restart it, but it wouldn't fire. Let it set for about 2 mins and tried again. Started up and a big plume of white/yellowish smoke rolled out of the exhaust. Tried getting it to a parking lot but stalled again... walked to the store and called a tow truck to give me a pull to a parking lot. Was about an hour before I got it pulled. Started it back up and ran great... got me home without any issues!?
- How was the truck running fine before this problem appeared?: Yes... I had just driven it 350 miles on a business trip to Virginia over the WV mountains... not one single problem.
- Has this problem ever happened before?: No
- Describe any related factors that might be part of the problem.: I really can't think of any.
- Have you checked for DTC (Diagnostic Trouble Codes)? (Y.N) Yes And?: Four codes came up. Code 18 (Not sure why since the pump it virtually new), Code 19 (Replaced, but code is still there), Code 29, and a code that has to do with my turbo... one of the senors. Can't remember which one sorry

I'm going to be taking some pictures and posting them to help... there are a few things I haven't mentioned here, but I will show with pics. Anything I left blank is because I haven't checked yet. I'm going to check the screen in my fuel filter housing with in the next few days.
Edit: Pics!
I think I did this when I was trying to get my crank sensor out. Yes that is one of my glow plug wires. It may have already been like this and I just didn't notice it until I spent a lot of time under the hood.

I dunno why the previous owner did this. He has what appears to be a ground going into my fuse box and down in-between my fuel solenoid fuse? Any ideas as to why he would do this?

Okay... I know this is going to sound dumb, but the grey box is the new model PMD right? And the black one on the side of the IP is the old one? Or are they two different things? Cause the black one isn't hooked up.

What appears to be one of my sensors to my vacuum pump/turbo.. not sure which one. Again I'm sorry I really don't know much about engines or vehicles in general, but I'm learning. The connector to this sensor is bad.. one of the wires is broken. Also, the black vacuum line that runs to this goes to my waste gate correct? I have looked everywhere for a schematic for the vacuum lines for the L65 engine and can't find any .

The original owner had a green vacuum line running from my waste gate to my air box... I'm thinking he did this for some reason... or is it supposed to be like that? The black vacuum line that I have hooked to it now is the one that runs along side the orange line running to earlier said sensor.

I'm unsure if any of these said problems are the cause of the surging and missing, but I thought I'd post them anyways just in case.. and yes I'm working on fixing these problems too either way.
