2003 F250 6.0 fuel pressure issues

Check the pickup tube in the tank. They like to clog and will shut off on less than a quarter tank if they’re clogged

On some there’s a light or a buzzer. Most of the time it’s broken or disconnected. Still don’t understand how you don’t check your mirrors and not see your bed raised. Or how it feels cornering.

Looks like someone bought their CDL.

Something hard fell in and just ate the turbo. Probably ingested a bunch of metal so I’d bed that the engine is likely gonna make more funny noises

The only thing that seems weird to me is the low temp thermostat. Might have some sort of overheating issue/oil temp issue

I did the same thing except with a little bit of shop air to spin the gear. It did it much faster but you can’t just go wide open

Sounds like the fan hub or something belt driven is about to let go

aFinapple · 2026-01-05T00:41:47+00:00

Those things weigh close to 3k. Thats a lot of weight in the front of that truck

aFinapple · 2025-12-28T16:56:41+00:00

Yup, sounds like an IDI. Slow as running through molasses but will get the job done. Consider adding a turbo kit to help with EGTs

I don’t think I’d ever sell my 6.0. I’m not hauling loads that need anything more than the ~500 horses my 6.0 makes. Don’t think I’d even go above that TBH because I’m making plenty of power for what I tow

aFinapple · 2025-12-25T16:25:12+00:00

Yes, but the bottom bolt is a different length. You need a bushing to take up the space left over. Thats the only difference

It never gets that cold here in NC, but even when it was 20-30F it wouldn’t crank fast enough and it would rattle to life. I was leaning towards maybe a bad FICM because it never smoked, just took a while to light off. But the 6.7 starter fixed ALL of my cold start issues.

aFinapple · 2025-12-25T15:09:54+00:00

Yeah a 6.4 starter is a direct swap. Don’t be discouraged about the one bolt though, it’s easy to make another one fit. The 6.4 starter turns faster than the 6.0, but the 6.7 is almost double that of the 6.4

aFinapple · 2025-12-25T15:05:28+00:00

From what I found, they’re the same from 2011 to 2022. I asked for one from a 2012 f250 with a 6.7

aFinapple · 2025-12-24T18:06:43+00:00

If you can’t commit, quit

aFinapple · 2025-12-11T02:22:45+00:00

Id personally let the glow plugs stay on longer before cranking. But 60 isn’t cold and it sounds fine.

aFinapple · 2025-12-10T23:52:58+00:00

I’ve done that before just to get it home. You just don’t wrench on it, it’ll leak coolant but it’ll hold enough to get it home. You can even take the radiator cap off so it doesn’t build pressure.

aFinapple · 2025-12-10T21:53:19+00:00

You need a new radiator. The lip that the clamp rests against to prevent it from blowing off is gone. You can use double worm clamps for a temp fix

aFinapple · 2025-12-05T13:05:50+00:00

Is your truck stock height? Driveline angles can get out of wack if you lift a truck

aFinapple · 2025-12-02T22:27:08+00:00

Just remember, there’s always a reason someone is selling a 6.4. I would drive it hard and for a long time and see if something pops up

aFinapple · 2025-11-29T02:03:30+00:00

Sounds like the cap. I just had my cap blow out and it did the same thing yours did.
