Looking for some input!!
OK, bare with me guys, I'll try to keep this short.
3 months ago had a bad injector replaced, at the time the shop said that I possibly had another one going bad on the other side, but I opted not to change it at the time.
Now I am noticing things getting progressively worse and had planned on doing a full injector swap with Hypermax stage 1 injectors. I have been having trouble with the truck starting recently and running progressively worse. I scanned the DTC's today and it threw these codes
P0562- system voltage low ( probably from the slow start and overcranking)
P0122- TPS circuit A low input
P0221-TPS circuit B performance
P0460- fuel tank level indicator circuit error (not worried about this really)
P1211- ICP not controllable- pressure above desired
P1670- EF feedback signal not detected
I am wondering if this could all be caused by failing injector, or do I have deeper issues? Any help or advice would be great. By the way, I have a 4 inch magnaflow exhaust and a Superchips Cortex programmer.
Thanks in advance, I can try my best to answer any questions you have about this. I am just a construction worker, not a mechanic though, so bare with me on this.

I would check the ICP Sensor connector for oil. If you pull it and it appears to clean, you should next look at the IPR Valve. It could be sticking, and that will cause a P1211.

as far as testing the injectors, I really have no need because I am replacing them with upgrades anyway. Looking at Hypermax stage 1's +50 hp gain. I really haven't had any acceleration problems, except one time on the freeway, I lost throttle response for about 5 seconds (no trouble since then, so the 0122 and 0221 could just be stored codes from that one incident). Mainly it is hard starting, smokes blue after start for about 10-15 seconds, and runs rough at idle and is lacking power.
I guess I am just looking for guidance... should I go ahead and do the injectors and slap some new batteries in and then go from there? or should I worry about other things first?
Thanks for your input td

The IPR is a valve, and not a sensor. Some people confuse it for a sensor because it has an electronical connector plug, but that is for the magnetic solenoid which drives the valve action based on incoming voltage (demand from the PCM). The solenoid actually just slides over the body of the valve and is a separate unit, but you can;t tell that unless you remove it from the truck.
If the IPR is stuck, one way to know is by using a diesel-compatible scanning system monitor the Injection Pressure on startup (I know AutoEnginuity works, not sure of others). If the pressure doesn't hit 500 psi really fast after hitting the ignition switch to start the engine (like within 1-2 seconds), then the valve is stuck and your system is not getting the required minimum startup pressure of 500 psi.
Regardless, with what you described about having lost the throttle for about 5 seconds, I lean towards the TPS as well.
Still, you should also make sure that you have full oil level as well to make sure taht your low pressure oil pump can supply your HPOP's demand when the oil is thicker (cold).
Could be multiple issues. When my IPR got stuck a short while back, I ended up having to replace not only the IPR but also the starter... just pure coincidence that they went out together.

Riffraff (Clay) in my signature is a site sponsor and has good prices/customer service. He carries Casserly/ Fullforce and alliant injectors. Check out his site and give him a call if you have questions. Do the stage 1's need special tuning? I'm not an injector guru.

I will check out Riffraff...thanks. I am not sure about special tuning, I am just going off of what was recommended to me by a diesel performance tech. He said I would be good with the stage 1's, with my programmer and 4 inch exhuast. I think I will give Riffraff a buzz for a second opinion.
Thanks to all of you guys for the help and input!

What are your early morning temps when you are first starting the truck for the day. Im guessing its starting to get cold in the desert. This may be as simple as a GPR(glow plug relay) that has gone bad.
How does the smoke smell in the AM on first cold start? Does it burn your nose and eyes, or does it smell like burned oil.

You need to test your glow plug relay. If you have a Cali truck you may have a GPCM(glow plug control module)
typing from phone right now, so I cant add in pic links.
Get a screwdriver type test light.
ground to negative battery post
touch inboard large lug on GPR while someone turns key to WTS(wait to start ) does test light illuminate? If no, then you have a bad glow plug relay.
order a stancor gp109 or get the NAPA equivelant and replace.
can somebody thatsw not on their phone post this man some pics.....

Also, been looking at the DP...what is the difference between the F5 and the F6? I am planning on a few mods soon and just trying to figure my best route. I am thinking 6637 intake mod, wanna do a muffler delete on my 4" magnaflow, stage 1 injector mod and a DP tuner.
You guys are all awesome! Thanks so much for all the input, I am learning more and more every day and hope I can help out others in the future

I think you'll be ok with the stage 1s and the tuner you have. You'll want guages though if you dont already have them to monitor things like EGTs. I would think that you may not burn all that fuel your dumpin in it maybe without proper tunage, but Im really not sure about that, someone will chime in.
As for the DP I believe the dif between F5 and F6 are that the F6 you can add tunes to it over on your computer at home and the F5 you have to mail back to Jody to get more tunes added. There may be other differences that I'm unaware of, not sure, I'd just call Jody at DP.

I like the 6637 kit I got from Clay. Riffraff Diesel: RDP 6637 Filter Kit
Are you going to install the injectors yourself? Maybe consider re manufactured ones. Between those two maybe you could afford a custom chip. I think they adjust for the flow rates in the programming.

I am going to do the injectors myself... I will probably be going with rebuilt. I am just a little strapped for cash right now, as are a lot of people and just trying to do what I can with my budget. I just know I need to do injectors of some sort and figured I would do the stage 1 upgrade now instead of replacing with stock. I will be putting in a gauge pod as well, to moniter the egt's, boost, etc.
should be able to get the DP chip soon after.
Thanks again guys for all the help and suggestions.
