For the past few months my truck has had a hard time starting up after a 100% fill up. (See video) If you hold the key long enough it may start. Or you’d need to move key back to acc and try again. Sometimes it starts right up 2nd or 3rd time, and sometimes it starts and feels choked and pops and you have to give it some gas and then it’s fine. This only happens after a compete fill up, any other time when less than 100% it starts right up no problem. The dealer replaced the Fuel canister purge valve, as I’ve heard of this being an issue, but no joy. No codes and I don’t think it’s the fuse 27 thing because truck will start eventually and starts anytime under 100% fuel.
Anyone have any insight? I’d like to point the dealer in the right direction other than blindly replacing parts. The video sounds like the starter is not engaging for a few seconds.
