Wish I could help bud, I no longer have this part. Unbelievable that this still an ongoing issue.

@Memo8642 Sorry bud, I do not. I just provided it to someone else in need.

@GregBFL I have the new GM part new in the box if want it.

@Sierra2020 Thats great news!

@Sierra2020 Just know that I have the correct part needed in event they don't. Will sell for what I paid + ship if needed.

Sierra2020. Did you find a part? I finally resolved the issue in mine with a new part. I have an extra *new* replacement part number part for anyone that needs. Brand new, unopened , Authentic GM 13558812 Fuel Pump Driver Control Module received directly from GM for anyone with a need for this module.

@GregBFL, Are you still in need of the fuel pump driver control module?

I’ll check on the junk yard version. The amazon version is chinese and is the wrong part number. see top row as you read right to left. thanks for trying to help!

I found a few trucks in salvage yards, but the module had already been stripped out.

I provided 3 from ebay to the dealer thas has my truck, none worked. They made me sign a disclaimer that said using a non-OEM part may jeapordize any remaining warranty. I added the sentence: "I take this action as a result of GM not being able to supply an OEM part", and signed it. Sounds like you've covered all the same bases that I did with no joy. I've spent 2 months seaching, calling, getting nowhere. I've had friends in other states search locally where they live - nothing. I was given a tentative date of 30 April and they have not called (as they said they would do weekly) or sent any further payments since the 1st. This speaks volumes about the lack of honor and integrity in today's GM leadership. The employees I've spoken to that have tried to help, quietly agree, but have no authority or options to do anything about it without risking employment. In the letter I sent to GM, I listed out over 1 dozen Chevrolets I've bought since my teens, many brand new. Does it matter to them? The evidence says it does not.

Wife has a car she bought the same day as I bought the truck, I've been using hers for the time being. Closest dealer (Carl Black Orlando) I took the truck to does not offer loaners only sympathy. Original dealer neither. GM offered to cover payments throughout the ordeal. They have covered January, and promised February 3 weeks ago. Nothing received as of this date. What a country...

I too am in central Florida. Mine has 27,500 miles. It's completely unsatisfactory behavior by GM. I've heard the same story from every dealer I talked to. Some even willing to agree and say as much (but quietly). Many trucks offline is the story I get. Mine is still inoperable waiting for the part. After my letter direct to GM, I got the call I mentioned 2 days later, then a follow-up call Tuesday last week. I was given a maybe-ish date 30 April and no guarantee that date was any good. They did state that it's definitely made off-shore (can't imagine where). Regarding my request to diverting some parts from the current production line, I was told that each module has vehicle unique calibrations loaded therefore diversion from the production line was not possible. If that is true, I thought, then divert the part and load the Calibrations unique for mine upon receipt. Pretty sure that was complete bullsh%$# because every GM tech manual I've read, and every tech I've talked say that no SW or Calibrations are required for this module. My research indicates the part has evolved through these part numbers: 13531875, 13558812, then 13540028. I've heard/read there was a fourth, but I can't confirm its number. I'm not sure how, but I think this issue needs the widest possible dissemination to be able to have some negative impact on GM, but I'm not sure how best to do this. Here's the diagram if you're interested.

I own a 2019 Silverado High Country. Truck has just under 30k miles at this time and is in pristine codition. Has run like new since the day I bought it. I love the truck, best I've ever owned. Just after new years on 2 Jan, went to head out to grab some things. Crank, No Start. Put a scan tool on and found DTC P129F. Had it towed to dealer and they confirmed. Was also informed part was on national back order. Still at dealer today. I was contacted by GM Customer Assistance 2 weeks later and was assigned a case number. I get weekly calls where they continue to convey NO ETA, and of course continue to coddle me with sorry, sorry, sorry and stories about the supply chain, etc, etc, etc. I've called well over 100 dealers accross America - back ordered. Those that had it, refused to sell to me since I didn't buy vehicle from them. A few busted their tails trying to help, but no joy. I've bought two (non-OEM), from ebay, neither worked. I understand that many customers are in the same sad position. I'm at my wits end. A couple of days ago, I sent a pretty nasty letter to GM - Mary's office. Got a direct call 2 days later - Friday. They took ownship of the issue and gave me new case number and said I'd hear back from them NLT Tuesday. We'll see. I'm a retired electronics engineer so everyday is pretty much a saturday these days. Decided to dig into to this part thoroughly. Service diagrams, TSBs, and more. Pretty much just a module that drives the 3 phase brushless fuel pump lift motor in the fuel tank via canbus (GMLAN) and it receives signals from the ECM over the bus when fuel is demanded from the tank. It talks to a few other modules as well using dc signals. As far as I can tell from reading whatever I can get my hands on, this module has been revised at least 3 or 4 times since 2019. Additionally, this very same part is used in numerous vehicles to include the silverados that continue to roll off the production line today. GM's priorities are obvious, new sales over support for prior customers. What frustrates me the most is why Chevrolet engineering has not designed an alternate part. This part is not that complex. I am just not buying the supply chain story. It seems pretty clear from this, and other like stories that GM has lost it's focus on Product and Service excellence it had in days gone by. To highlight this point, my wife bought a new Blazer Premier the same day I bought this truck in 2019. It has 3 times the mileage compared to my truck and she loves it. So much so, she was temped to buy a 2024 Blazer EV - not that we're big EV fans. This one got rave reviews right up until the point where GM put a stop sale on them as soon as they started arriving at dealers due to a complex set of software issues. The stop has yet to be lifted. What the f^&k GM? It seems that GM is heading in the same direction as much of the country - no leadership and increasing incompetance.

Will do, looks like a 2-3 day ship on the connector, so I'll be able to give it all a 1st attempt this weekend...

I have a 19 HC as well as the trailering aux camera kit and just ordered the connector # that 2kSierra was so kind to provide. I'll connect the existing tied back camera cable that's already present behind the license plate to the new connector once I receive it. Then, plug in the aux cam kit I already have and see where things go from there.
