I had the lifter failure at 90,000 with my 19 Silverado. Mechanic got it all fixed up but instead of taking it to the dealership to have the computer re programmed, he was told by his "computer guy" that you just install the Pulsar LT and I wont have to spend the high dollar cost at dealership to have them do it. All was great at first but I noticed the oil alert would go back to 9% right after it is reset, also the Change air filter alert was doing the same thing, I could reset it and it acted normal but next time I start it up, the Change oil and change air filter alerts were back on. On the fourth day, I was driving home and it went in to reduced power mode and said service parking brake and service ecm I think? Anyone ever heard of using the Pulsar for this? I think it is causing the problem. Mechanic replaced lifters, cam, cam bearings and crank bearings. Help! I want my truck back!!

Looks like I have to get the Diablosport Pro and have it custom tuned to make it work. It is on order and I will try to remember to come back and post what my results are.

Only reason it would have to be "re-programmed" is if some WA cam was used to replace the stock one.  As well, why replace some of the bearings and leave the rods? 

Still sounds broke to me.... maybe seek restitution if the original estimate included a quote for the "dealer re-program" and find another "mechanic".

And the warning was service esc (not ecm like I said).

ESC is a warning for the Stability Control, did you go after market with the cam swap or are the parts all stock and if they are stock, why the need to reprogram anything? I'm thinking at least for the ESC warning is that the mechanic didn't put everything back together 100%, i could be wrong though this is just a hunch as those are errors are for things like traction control or abs systems.

New here;  

Hi all.  So the other day my 2020 2500 Sierra decided to start acting up.  My service esc, 4WD, Parking brake and TCM lit up.

Then I got the message of reduced power to protect the vehicle!.  Low and behold,  after trying some different tactics decided to play with the remote starter fob and VOILA..  Truck issues all better.  The morning my problems started, I had remote started the truck with the FOB and it ran the full cycle; before I actually started to leave for work!    So when it shut off, it went into a funky chicken Valet mode or something and messed the computer.

 

P.S. I have one minor annoying issue still.  If someone could help me, I would be grateful!

My Parking brake goes on automatically when I shift to PARK.  Anyone know how to reset that feature?

Cheers,

JO

      Post your UOA, (used oil analysis) here

      By Black02Silverado · Posted

      Here's the second UOA on my 22 Wrangler with the Ecodiesel. This has 5k miles on AMSOIL Signature Series DEO 5w-40. The first one was dealer installed oil, no clue what it was, the second is what AMSOIL recommended, European FS 5w-40, Most of the Ecodiesel world is showing great results using the European MS 5w-40, I figured I would see how the DEO works. This is using an Ecoguard oil filter. It's my understanding this engine likes to shed aluminum.  We will see. So far I don't think this is too bad.

      Disable DRL's

      By revmanii · Posted

      I'm surprised nobody seems to offer a solution like the start/stop device I put in my new truck. Remembers my setting when shutdown. And while it still starts up in start/stop, it stores/evaluates what mode it was in when shut down and will change it whithin a second or 2 of startup. It'd be nice to have something like that for the DRLs.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.

      An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
