I have an 03 Ford Focus and after a friend ran a diagnostic, it turns out the fuel pump needs to be replaced. Ive always put low grade gas in my car but never bothered w/ fuel additives. As a result, sometimes the car will stall and lose power especially when in 3rd gear. Will using fuel additives help or is it too late for that?
No chemical can fix time and wear. I do have an idea, though. If you're looking to save $, try replacing the fuel filter first, and run the diagnostic again. If the filter was bad enough, it may look like a failing pump to a computer.
too late for that. once a fuel pump starts going, there is no turning back
which would you enjoy hearing the most some music or the sound of the engine i would go with the music 1st
I would test the fuel pressure. One big thing I would do is replace the fuel filter, which should be done every 50,000-100,000 depending on the vehicle. They clog up and will hinder fuel flow. Another possibility is the fuel pressure regulator. I would replace the fuel filter, and then run a fuel pressure test though to see where it's at and if it's in specs. Hopefully that fixes it. If not, then test your fuel pressure regulator. If that's good, and your fuel pressure is still down, then yes, replace the pump. Fuel additives will probably not help at this stage, although Lucus injector cleaner is awesome for cleaning your fuel injectors.
