Check Engine Light P0232 Fuel Pump?

[awright2009]

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

Can you give some current info?

What year?

Mileage? 

Engine?

Previous maintenance recently?

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

Just checked the codes again today, without any drama from being stuck in a roadway, turns out there is one more code now: p023F

 

Which is the same set of codes this guy had:

Which leads me more to believe it's the fuel pump

Decent video for changing the pump, different vehicle shown, but it's pretty similar and this one is decent in terms of technique

 

 

 

And the fuel pump part number kind of shows the bolt locations in the explode diagram:

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.
