I made it a point to contact @mountaindan on the phone today and try to help him out. Anyone near Dan would be a service to help him out.

You could look at the 911 listing and see if there are other members near you that might be willing to help. https://mopar1973man.com/cummins/911-support.html You could ask other members here in the forum to help you. Most guys here are really good at being helpful and helping with doing repairs on trucks. I'd love to help but I'm on the wrong side of the island from you.

Sorry to hear that. All I can say is you might pay more money for taking to a shop and have some shop monkey wildly guessing at the problem charging you large amounts of money. There are things on these truck that is considered maintenance items like injectors. They are supposed to be replaced every 100k to 150k miles for the optimal performance. I know many people will say they ran their injectors over 400k miles and never changed them. Might be true but the fuel economy typically is much lower. Sorry to say 230 bar is junk its way too low and will not atomize the fuel well at all. It will create misfire conditions. This is why some of us are experimenting with high pop pressure about the 330 bar realm to find out if there is anything to gain. Like myself as soon as I can get money ahead I'm planning on pulling my +75HP injectors out and going for (7x0.010) with pop pressure of 330 bar. As the pop pressure goes down the injection event happens early and and not sprayed in fine mist but a squirt. Remember two things are needed for diesel to run well. 1. Compression - Valve lash in good adjustment, cylinder health (good piston rings and no blowby), boost pressure. 2. Fuel - Sprayed in the cylinder in a fine mist at the right time.

All right here...

Tach working? Any P0336 error code? If there is any error code for tach signal (crank sensor) the ECM will not know to start the lift pump. Does the lift pump run when you bump the starter? Is there 12V from the lift pump lead? If not then you looking at sending the ECM for repair. WARNING I do not suggest putting a toggle switch on the lift pump or wiring the lift pump to the key switch. This is a huge safety hazard if you in an accident there is no way to shut down the fuel if you are unconscious. I highly suggest you have the ECM repair then replace the lift pump with an AirDog or FASS with a protection relay so the load of the pump is never on the ECM.

Hype... Typically when the P0121, P0122 or P0123 code is present with the "Dead Pedal" its going to be APPS sensor issue. The bast way to test is to have a live data tool and data log both Engine Load and the APPS sensor together in graph form. The engine load reports the amount of fuel given to the engine. So if the APPS and the Engine Load drop together its a APPS sensor issue. If the APPS sensor stays high and the engine load drops then it could be an ECM issue.

Not a problem...

Here you go.

Thanks, I feel the love...

Finally after 10 plus years I went in and got new glasses. My old glasses where giving me random headaches and struggled to read road signs and some days even the computer screen. Nice part is this is the first time with polycarbonate lens. Wow! Much lighter on my nose. So here is my at home desk glasses. Geek stylin' Now my driving glasses and clip on polarized shades. I've got a wide range of vision so the larger lens really help with driving.

Point taken... Some of us are stuck with what we have and don't have a little car.

Basically room for improvement.

Gotta ask. What do you get for pretty decent mileage? I'm also a daily driver for the most part. Approximately 750-1000 miles a week.

230 bar is junk. 293 to 327 bar is stock range. Stock set is 310 bar. Might explain poor running.

What pop pressure was the injectors set for? Were the injectors flow matched?

Personally, pull all 6 injectors and have them pop tested. As far as I know... I would say no. Basically an injector is waiting for pressure from the VP44. As the VP44 pushes pressure into the injector it has the power to over come the spring and lift the pintle firing several pulses of fuel in one stroke. As an injector wears it just fires sooner and lower pressure so the droplets get larger and more like a squirt gun. As you apply throttle you just raising the pressure to the injector. So at idle its right around 4,500 PSI so as you apply throttle you increasing the line pressure. So I doubt it's an injector but to rule it out I would have the pop tested.

Some days I would love to jump into the newer technology but the same time I really don't want to have to learn all the repairing process and finding out all the special tools and diagnostic tools you need to fix these vehicles. Kind of like in the past older PC's I used to assemble had expansion slots for different add-ons. Now today most motherboards are designed with everything on board already. So now saying this its the same way with the vehicles back in the past you had options to add or remove different options. Now vehicles already come with all these option built-in and don't give you an option for change or modification much.

It will put stress on the pump pulling a hard vacuum all the time. Neither FASS or AirDog isn't really designed for 3/8" hose.

You can do the iQuad head for now and then buy the iQuad BT head later. Geez... You buy music? Maybe you should do it like us Linux/Android folks do for FREE... https://www.mp3juices.cc/ I've never paid for music.

Like my LG G5 phone allows for either 2 data stream over BlueTooth or 1 data stream or 1 audio stream. Might consider changing phones. Android / Linux we've got cookies over here.

Yeah true. You can find Tablet's for $40 bucks and have a pretty good sized screen too.

When I bought moparMom here LG G4 phone it was only $200. Then when I bought my LG G5 for my self which I'm currently using it was closer to $300. You could if you have a phone like my LG G5 which is dual Bluetooth. So I could hook up to two separate bluetooth device at the same time. Yes. Correct there is no cooldown function. No defuel function for over temp either. Or come back here and download a custom tune from the download area. Not required. I'm only using 8 levels on my current tune. Totally selectable on how many levels you want to have. The level 4 to X is how much you split up your wiretap. Since I've got 8 levels that means 4 (25%), 5 (50%), 6 (75%), 7 (100%). Also, remember the count starts from ZERO.

That is correct...

Yes. iQuad is WiFi and iQuadBT is BlueTooth. I'm using a LG G5 phone (android). https://mopar1973man.com/topic/12976-getting-the-most-from-a-lg-g5-cellphone/ Beyond that no, that I know of. That's up to you. I've been using my android phone as a phone, MP3 player, iQuad, and OBDLink app. I can voice command anything I want and even send text messages without touching the phone. Totally up to you if you want 2 devices in your truck on one. No. Fuel pressure is extra. I didn't install a fuel pressure for the iQuad. Good. This means you can run the Quadzilla headless. In other words you can set it and forget it. No need to fire up your device everytime. Also means no one will know there is even a tuner present. I'm also the same way I don't really use the gauges on the iQuad but I already have full set of gauges now on the A-pillar. This more fun because people think the truck is stock now. Even more fun when they come un-corked when the power comes on. Then they ask where is the tuner? No, you cannnot piggy back. Myst be a second probe installed.
