I bought my 2500 Custom in August 2020; and love the truck it has everything I want and nothing I don't, but I'm loosing faith in it. About 4 months after owning it, it left me stranded. It would turn over but not start, oddly enough it didn't throw a code; I called my dealer and they didn't know where to start without a code, so I figured it's under warranty so once I got it started I'd run it like some anomaly and surely it wouldn't happen again. But I was WRONG! After being stranded (delayed) 3 more times it finally threw a code, (August 2021) I got it read at a local parts house cause the Chevy house want $150. The codes were P12A6 (fuel pump driver control module) and P00C6 (fuel rail pressure low during engine cranking), I called my dealer and they said yes they are having problems with the fuel pumps. I took it in at the beginning of September 2021 they "fixed" the fuel pump and the truck ran great! Today is September 30, 2021, yesterday, the 29th, it left me stranded again. I got it started and headed straight to the parts house, and again the code reader said it was P12A6 (fuel pump driver control module), back to the dealer on Friday.
Is anyone else's 6.6 gasser eating fuel pumps?
