How do I best troubleshoot a P062A code? It's a 2017 1500 series with the 5.7l Hemi. The truck has 157k miles on it but the engine was rebuilt at 140,000 due to the infamous lifter issue where the cam lobes were worn down. History is that several months ago I got a P018C code. I replaced the fuel pressure sensor at that time with the new partno that required rewiring into the harness. That code never came back. But also for several months now, the truck would stumble briefly on the highway but not stall. It was random and very infrequent. Yesterday I had a looong drive and it started stumbling more frequently. Just for a second or two but more frequently than in the past (a few times an hour now). As I got home, the check engine light came on and it is the P062A code. It also won't remote start but I'm thinking that's because the CEL is on. But it starts by keyfob with no problem at all - at least for now. That code has to do with the fuel pump and circuity but what is the best way to troubleshoot to minimize the work and not throw parts at it? Especially because I'd have to drop the tank to replace the pump itself.
