You have two pumps,I guess you know that ,if you already did one. Did you check fuel pressure at the rail and check out the electronic pressure regulator? What codes are coming up and do they stay set?

I think that the 2002 accents still have a external fuel pump i would change that but to be shue it is a fuel problem remove the fuel line from the fuel rail and cycle the key on and off checking to see that there is no fuel spurting out of the line. New fuel pumps aer extremly quiet

Sounds like a bad cell(s) in your battery. They will not hold a charge very well if they have been damaged or sometimes at all. Your charging system is probably running the engine most of the time which gives little room for charging the battery, and when it sits the little bit of charge is now just enough or not enough to get you going. If you can, try having the battery load tested (usually free) and also have a mechanic take a look at your alternator while your there. I think your alternator could be dying which is how you got a weak start from the battery if it turns out that the battery is ok.

you may have to drive it several days for the light to go off, or have the codes cleared. personally I would just drive it. if the computer tests it, and it passes the test, it will go off on its own.
