Hello. I have a 5.0 2015 with push button start. I have a random issue that seems to occur when the engine is warm (sitting for 1-3 hours). It sounds like it's barely going to start or like it's not going to start. I've had the battery tested and it was fine. I have the same results whether I use remote start or the push button.
I'll try to get a video later today to post, but I would say it's a few seconds longer than normal. Long enough for people to notice.

I know you said you had the battery tested and it's good but...

I'm going to say when this is solved it turns out to be the battery.

That at would be my guess also but this doesn’t happen first thing in the morning after it’s been sitting a while. Nor does it happen a few minutes after stopping like when at a store. It’s only after sitting for a few hours.

Just went through this with a Daughter. Starts fine in the morning. Only had the issue after the car had warmed up. Virtually the same scenario as yours. Was told by two different parts houses the battery was fine.

Here's hoping you get it figured out.

Update: I've tried to prime the fuel pump by pressing the On button, then a few seconds later starting the engine and it would start in normal time. I think it's odd that it cranks on a cold engine just fine, but if it sits for the 2 - 5 hour range, it takes a while and barely cranks.

Well the dealership can't follow instructions and therefore can't reproduce the issue. If it sits for several hours, it's a several second start. If it sits overnight or is within an hour, then it cranks fine.

No updates yet. I’m thinking I have a slow pressure leak in the fuel system. I’m seeing a slight improvement if I turn the truck on for a few seconds before starting. Still a long crank of it sits 2-6 hours. No issues first thing in the morning.

Do you know if a small leak while sitting can play any role in while driving?
