2014 Ford F-150 troubleshooting (engine sputtering)

[mikeyb_23]

The throttle body might need a good cleaning.

I’m going to clean the MAF sensor, and throttle body to see what it does. I bought plugs, can always pick up coils. Just trying to figure the best route.

Fuel pump or vacuum line broke. Spark plugs need to be done anyways, though. Super easy. I've got the same motor and did them about 2 months ago. Love that motor.

Check fuse #27 fuel pump it's a 20 amp fuse.
I had a similar problem and the fuse wasn't blown but on one side it looked discolored. i simply replaced and haven't had any problem since.

My wife's 2012 w/5.4 did the same, all at once like you stated. If you've never done plugs I'm pretty sure that's your problem. Much more common then a failing fuel pump.

This happened to mine as well. It's been a while ago but I think it ended up being the plugs. There could've been a coil too. I can remember that it was NOT the fuel pump.

Yea. My thought on the plugs as well. Did you change the coils with the plugs?

No. Just the plugs. So long as you have a good spark, the coil will remain fine. It's the plug that's exposed to the heat and combustion and will give out over time. I bet all the plugs are gapped way over if those are the original. You'll probably gain a few more ponies and mpgs afterwards too.

It’s already happened once about 6 months ago. I was hoping it was the same this time, fuse 27 was good though. So on to the next trouble shoot

Even with it starting up fine every time?

I had this exact problem on my ranch truck. Dumped a bunch of money on ignition parts. It would start up and rev for a minute then struggle to stay running.
Wound up being the fuel pump.

New plugs for the win!!!

I’m sure I won’t be too long on the fuel pump with my mileage though

Glad you got it figured out.
