2015 Tahoe Fuel Pump Control Module

[RevealTheKraken]

So yesterday the family and I were 2 hours from home when at a red light I started to accelerate and the truck shut off. I coasted the shoulder put it in park, shut it off, and waited a minute. When I restarted it, it ran for maybe 5 secs and died. I then noticed the CEL was on and of course my scan tool is at home. I try a few more times to crank it and eventually it starts and we take off to the closet parts house that will scan your vehicle for free. I don't dare shut it off they scan it and come up with P12A6 (fuel pump driver control module enable circuit performance). So since the truck is running and I don't want a $1000 tow bill, I decided to head towards the house and see how far we make it. We made it the 2 hours back no issues. It starts and runs fine after we make it home for the rest of the day.

At this point my first thought was this is a 10+ year old truck in Northern NY and I have had a few trucks over the years where a module would rot out and cause issues. I get a wild hair this morning drop the spare and look at the module. Looks ok on the side I can see no chaffed wires or obvious damage, so I get more curious pull it off and sure enough 2 giant holes in the back. Temporally I have taken the lid off the back cleaned it out with rubbing alcohol and made sure nothing is burned and shorted. Placed the lid back on the best I could electrical tapped the lid on. Placed it inside a thick rubber glove. Plugged it back in and tapped the end down with tape again so no water or debris can get inside and zip tied it to the factory bracket.

Not a big deal right? They are only $100-$150 depending on where you buy them. Until I start reading conflicting stories about having them programed. I found 2 on rock auto the OEM one (23382215) and a STANDARD MOTOR PRODUCTS (FPM124). The OEM says right in the description it needs to be programmed and the SMP one does not. In fact I found the exact one on another site that specifically says it does not need to be programmed. I have found tons of info on previous and newer models but not a lot on this year truck.

TLDR:
Truck has a crank no start condition for 5 mins then runs fine. P12A6 (fuel pump driver control module enable circuit performance) code. Found hole in fuel Pump Control Module. Cleaned it and protected it from weather and the truck runs fine at the moment. The rest it below.

2015 Tahoe LTZ
140,*** miles
No issues before except electric running board motors getting stuck down.

So my questions..........
Has anyone used the SMP (fpm124) module without programing with any luck?
If I drive the truck to the dealer, replace the module with the OEM (23382215) in the parking lot ( takes 3 mins with the tire down) will they program it for me or will they give me the whole "we have to diagnose it first"?
And also just curious on the cost to have it programmed? Watched a few youtube videos and with the right software it takes all of 5 mins to do it. I know dealers have to pay license fees and such for all that software which is why the price is higher than expected.

IF I was just trying to get the fuel module programmed and was trying to save a few bucks I would call around to any local mobile mechanics and see what there rate is versus a independent shop and versus what the dealer will charge.
your kind of in a place where a moderate tool investment would be a one time investment that would pay you back over time if you are planing on keeping the vehicle and want to do repairs yourself, a couple avoided trips to the dealer is money you didn't have to spend. (which is were the tool pays you back)
other than that a dorman may not have to be programmed IF they make one for your 2015
I would not recommend using the standard motor products, that brand is prone to failing either in short order or just out of the 1 year warranty.
dorman sometimes gets a bad rap as well but if you buy it from a authorized dealer they do have a lifetime warranty.
I would recommend the oem if that is your only other option
or if money is tight try and find a good condition used OEM one like on ebay, the west coast vehicles are not prone to rusting.

I ended up ordering both the OEM and the SMP one. Figured if the SMP one works cool if not I have the OEM one sitting here and then a trip to the dealer. Unfortunately, there are no mobile mechanics in my area and all the independent shops I talked to said take it to the dealer. We had planned on trading it in next year but it looks like that time frame may have just moved up a few months. I bought the new Gearwrench tablet scan tool this year and it programs keys and other things but not the fuel pump control modules go figure.

some modules can be learned with a decent scanner and some need to be done with gm techline connect via a windows 10 pc/laptop/tablet and a compatible interface
gm charges $45 per vin for like 2 years of programming. It is all done online and thru the pc & interface adapter.
a dependable adapter runs about $300 and up
a vcx nano is around $120 but can be troublesome to setup it normally comes with a some hacked gds2 / tech2win software, but that can be a rabbit hole to make it work and then when you do get it working gm updates there software and so the hacked version has to be gone over again, you usually 2-3 month working window and then you have to repeat the setup.
and beware of knockoff gm interface adapters like a MDI or MDI-2 those are now showing up with malware (trying to backdoor into gm) and if you try to use it with techline connect you can get blocked and banned, some people are finding out the hard way....
