I have a new 131 mile, less than one week Silverado Trail Boss 5.3l and the truck would not start.

Four tries with the key, a remote start attempt and just engine cranking.

Called On Star and asked to have it towed.  Sat for about ten minutes and tried again.

This time it started but a check engine light was set.

I had it towed anyway.  Dealer said the fuel pump module was bad but truck is running and they cleared the code.

GM agreed to replace the module.

Anyone else have a bad fuel pump module?

Well it looks like no one else has this problem.  Dealer has the part on order.

Truck is running.

Word for word same issue except at 1,600 miles.  Not giving me confidence in the truck.

Module was replaced and the issue has been resolved.

Check engine light came on my new 2020 Trail Boss at 950 miles. Diagnostic test pointed to the fuel pump. The dealership is replacing the fuel pump. I'll let you know what happens.

I had that issue but didn't know it. Had it in for the hard shift. Code came up at the dealer. So fuel pump was replaced under warranty took them more than 2 wks to get part and fix.

2020 trail boss 6.2 175 miles on it.  I just drove it home from the dealer and it wouldn't run the next day.  They hauled it back to the dealer yesterday and waiting to hear the results.

Haven't seen fuel modules be a major issue since the early GMT-800s.. (99-03s/04s)

I have a brand new 2019 GMC SIerra Elevation with the exact same problem.

Dealer fixed and replaced the pump but now the pressure sensor is being replaced as it has now thrown a code this weekend.

Will let you know how this goes.

2016 GMC Sierra, went out this afternoon and truck would not start. Code PO23f. Tried starting multiple times. No luck. Will be contacting the dealer today.

I just received my truck back and they replaced the fuel control module.  Hopefully it holds up.

Sounds like GM got a batch of faulty ones.

I had the same issue pop up after 500 miles. My truck has been at the dealer since May 7th and still no part. About to make my second payment on a truck that hasn't been in my garage for just under 7 weeks.

    • Hello hello looking forward to expanding my knowledge of the 2026 2500 HD that I just bought.   Truck has 3500 miles on it four-wheel-drive crew cab and I’m about to put a 6 1/2 inch BDS lift on it 18 x 10 -25 offset with 37’s   Already have the wheels and tires just waiting on the lift install in about three weeks   Question what surprises am I not gonna be happy with?  I’m not new to lifted trucks so I know that acceleration towing gas mileage all that is affected..   Question is those of you that have this truck this powertrain with a 10 speed Allison and have done the mods that I’m doing,,, how bad is it? Is that Allison constantly gonna be hunting for the right gear to go into? And what about towing, acceleration, fuel consumption as mentioned?    Lastly how come I can’t find any ring pinion gear set up for these axles and when could I expect to see them?   I apologize if there’s any typos I’m doing speech to text on my iPhone.    
    • I've got a 2013 2500 6.0L Flexfuel. Drove the truck earlier today with no issues. Went to run an errand tonight and noticed key fob wouldn't work. Figured battery was dead, so replaced fob batter. Still wasn't working. Grabbed my other set of keys with the other fob and that one wasn't working either. So I manually unlock truck and insert key. Interior lights come on, dashboard lights up, turn key and truck starts. Turn truck off, like a moron, and try starting again. This time no crank, no click, no nothing. Lights still come on and dash lights up, but now I'm getting a service 4wheel drive, service tire monitor, etc. Check voltage on battery and Im showing 12.2v. Throw my battery charger on it and give it 15 mins and try starting again. But still no crank no start. Decide maybe its a bad battery, run to autozone grab a new one and put it in. Same issue. Disconnect battery and let it sit for 15 mins. Try again and still nothing. I had managed to roll the windows down earlier as its a humid night, but now I can't get them to roll up. Power locks are also not working now. Then randomly I try the key again, and it fires right up. Immediately I roll up the windows as we have nothing but rain forecast this week. I shut it back off wait 30 seconds and start up again. Worked a 2nd time. So turn it off, start putting things back together. Try one more time, and back to no crank no start. And now the car alarm starts going off. Had to disconnect battery and leave it that way for the night as I don't think my neighbors would appreciate my alarm going off again tonight. Any thoughts or help would be appreciated. 
    • No one will care for you like you care for you. Do what you can for as long as you can. IMHO of course. 
    • How about them NICKS!!! 
    • Hi there.  Long time lurker, first post.    i have read the previous posts regarding the water ingress problem with this emblem.  I bought my 1500 SLT the  summer of 2025 new and after reading the MANY problems with these emblems failing I decided to install one anyways.  As per a YouTube video, I sealed ( or tried to) this sign with silicone sealant around the outer perimeter joint and the holes that were already somewhat sealed on the rear plate of the emblem.  And installed the connector assembly using dielectric grease on the connectors. The installation looked great and worked well for about 4 months……then FAILURE.  Grrrrrr…… I live in the great white north and wash my truck weekly in an automatic car wash  to keep the salt off.  Let me tell you that removing the old, failed emblem is a whole different animal than removing the OEM individual letters without removing the grill assembly. Mainly because the illuminated logo is built differently than the original letters which  you can remove the red surface lettering with a knife or some kind of blade which gives access to the tabs which hold the logo onto the grill. So I had to essentially destroyed the old emblem to remove it. Doing so killed my chance of doing somekind of autopsy on the failed , old logo.  But there was plenty of water inside when I ripped it apart.  Prior to installing the new assembly I tried it with the old harness and it works fine.   Does anyone have any insight as to where the water is getting into this emblem? I intend to seal the new logo with slow curing epoxy this time around using a syringe.  I think this newer emblem may be an updated unit which I hope GM got the vendor to fix. It has an October 2025 date on it.    If this one  fails,  I am just going to revert back to the non-illuminated letters….AFTER PULLING THE GRILL.    Any thoughts on sealing with epoxy would be appreciated. Thx!   Doug
