5.4 no power @ high RPM
Hi, new to the forums, looks like a good place to be
I have a relatively simple question that I just want confirmed before I buy a replacement part.
2005 F-250 Super Duty, 5.4 gas.
My truck falls on its face when going into passing gear, it actually slows down. I've got 3 engine codes P0191 fuel rail pressure, P0171 bank 1 too lean and P0174 bank 2 too lean.
The truck is also hard to start after re-fueling, but starts like a champ any other time.
I changed the fuel filter and nothing changed, so I'm assuming a fuel pump. Now, before I go out and buy a new fuel pump I figured I'd check to make sure it's not something else that would make me say "D'OH" after changing the pump.
Another question would be where to buy a fair priced fuel pump
Thanks

Hmm...my 04' F250 5.4 gas truck runs like **** now too. It was badazz when I got it...now it falls flat on its face when I stomp it. I already changed the fuel filter and exhaust manifold gaskets to get rid of exhaust leaks which was probably making a rich condition (I am planning on an exhaust system with my tax return...any suggestions?? Magnaflow??). It has a stock replacement K&N filter....I just blow it out with air...I never oil the stupid thing, as I know what MAF sensors cost! LOL Anyhow...it still runs ****ty. I need to get my dad to put his Snap On Solus Pro scanner on it and see what the hey is wrong. I have big power plans for this thing...as I am a drag racer, and want my tow vehicle to to haul the car and haul AZZ!! I don't want my dads 2000 Chevy Silverado to beat this thing ANOTHER DAY!! Its making my mad! Any suggestions of what else to check?
