Hello all. First post here. It’s been a useful place for info so far. Here’s my situation. 2020 Z71 sbcc. Threw a fuel code with about 5000mi on it. Code cleared itself, dealer said my fuel might have gelled, because the light came on at 32*. Fast forward now at 9000mi. Start truck one morning, it idled rough for a minute, then died. Repeated this 5 times that morning. Take it in, they don’t know what went wrong, referred it to engineering, they don’t know what happened either. So they are replacing the HPFP, fuel regulator, fuel rail, and filters, even though it’s currently running just fine. From now on I will be using a diesel additive, but I’m just curious what the issue is here. I bought this thing over a Tacoma believing it would be reliable and last me 15yrs. My confidence isn’t so high anymore. Curious to hear theories. Thanks.
