Check Engine Light P0232 Fuel Pump?

So, driving to the home depot this morning I didn't get too far, when accelerating the engine died and a check engine light appeared. I was able to restart and limp it closer to home, before finally towing it with the front tow hooks and a strap with my dad's truck.

 

So google says this generic OBDII code is something like: P0232 is triggered when voltage in the fuel pump secondary circuit is shorted to vehicle power through the relay

 

Which searching around on here seems to be related to the fuel pump, which makes sense. I recently put some old gas from my motorcycle and an old gas can into the truck to burn it, this was a tank and a half ago though, so I would have assumed it was all used up. (maybe 5 gallons total of old fuel) I think the gas may have had some stabilizers or cleaners in it, so maybe those loosened some trash up in the tank. But who knows maybe the pump just gave out, but I figured a clogged fuel pump would quickly draw a lot of power causing the ECM to kill it to prevent it from burning itself up.

 

Looking around online, it seems people either drop the tank, or loosen the bed bolts and lift the bed to access the fuel module at the top of the fuel tank.

 

I figure I'll just use AAA to tow it to the dealership and have them fix it, as dropping a tank is always a pain in the behind. I suppose I could try to figure out if this is an electrical problem instead, but I highly suspect a clogged fuel tank.

 

Let me know if I'm on the right track or not, maybe it's not the fuel pump at all

Oh yeah, 2014 Silverado 5.7L 127,000 miles, so it's probably due to go out just from age. Maybe the fall season cold morning temperature cycles contributed some. Maybe my old gas was fine, but timing seems suspect, it looked a little green but I dont think it had anything floating in it.

 

Never had any issues with the fuel system before now, I usually run Ethanol, but have maybe 75% gas to ethanol currently, only thing I've really done on the truck was the A/C condenser in terms of service

And I’ll chalk this one up to the “I should always do things myself”  column, picked up from the dealer $1423.15 for new fuel pump installed 


Breakdown was something like this give or take (not exact from memory left the paperwork in my truck)

 

$169 diagnostic

$69 15% shop service fee

$400 for part

$900 for labor

 

 

I was expecting $900 total (which even I thought was high) but cost way too much. But it was very convenient as I didn’t have to do anything.

 

Supposedly should be 4 hours of labor, so labor rates must be outrageous

That price is painful.

      OCI, not when but why?

      By Grumpy Bear · Posted

      One would think. BUT....This is what a Google search gives for the GM OLM system:    It doesn't measure oil condition save the highly indirect water temperature. It should measure oil temperature and as we've discussed they are not as closely related as one might assume. The algorithm is based on expected conditions at the end of a certain number of miles or revolutions. And sirs, this estimated value is not tilted in the engines favor. It favors the OEM's bottom line. There are no magical number of miles nor revolutions. No magical time limit. There is only what can be measured directly and only in the broadest of terms would the values used even come close to reality.    It samples nothing. It has no idea where the oil started or where it will finish given the limited values use to create the algorithm. It is just a reminder for the brain dead to do something at some time to keep the warranty in tact. Pure fiction.    Key Factors in Oil Life Calculation The OLM calculates the remaining oil life percentage based on the following factors: Factor Description Engine Revolutions Tracks the number of engine revolutions since the last reset, decreasing oil life with use. Mileage Since Last Reset Monitors the distance driven since the last oil change, capped at 7,500 miles for most models. Time Since Reset Decreases oil life over time, dropping to 0% after one year, regardless of mileage. Engine Temperature Adjusts oil life based on coolant temperature; exceeding 260°F sets oil life to 0%.

      Towing power and I guess MPG matter that’s why I may end up going with a gear swap as soon as they’re available for this truck if I’m correct

      2027 Chevrolet Silverado: Official Discussion

      By GMTruckGuy74 · Posted

      If I may, I'd like to post my prediction of the trim levels for the 2027 GMC Sierra, based on what was released/introduced today about the Chevy Silverado.   Using the "Professional Grade" wording already in use by GMC, here are the eight (8) trims I believe the Sierra will offer (comparable Chevy trim in parenthesis): Sierra Pro (Work Truck/WT) Elevation (Custom) Elevation Premium -or- Ultimate (Silverado) AT4 (Custom Trail Boss) AT4 Premium -or- Ultimate (Trail Boss) AT4X (ZR2) Denali (High Country) Denali Ultimate (N/A) If GMC would rather simplify the trim levels, then I predict six (6) with package upgrades in parenthesis: Sierra Pro (with a Graphite package upgrade option) Elevation (with a Premium -or- Ultimate package upgrade) AT4 (with a Premium -or- Ultimate package upgrade) AT4X (with AEV and Ultimate packages upgrade) Denali Denali Ultimate  Let's see if I'm close.

      Auto start stop disable

      By revmanii · Posted

      I have to believe there are already a bunch of threads on this, but my searches didn't turn up much. While I like the ease of a plugin solution like the Carbyte, It appears it disables the AFM or DFM too, and is not configurable to only disable the auto stop/start. So, I'm looking at the Autostop Eliminator product. I like the idea of it better, but I'm concerned about the install and having to pull so many panels to get it installed. Mines a 2026 work truck, so from what I've read it's a less involved install, but having watched a couple install vid's, I'm still a little intimidated. Might need to buy some plastic trim tools to get it done without breaking or marring stuff. Any experience intalling in a WT greatly appreciated.
