What exactly is the problem?

sounds like fuel starvation,vaperizing,fuel filters

MAKE SURE YOU HEAR FUEL PUMP RUNNING IF NOT REPLACE FUSE AND RELAY. CHECK FOR FUEL PRESSURE.IT SHOULD BE 43 PSI.IF NOT REPLACE FUEL FILTER.IF PROBLEM STILL EXIST FUEL PUMP THE PROBLEM.

I have an '03 Hyundai Accent 1600cc. I am told by the techies at the local dealer, the fuel filter is ON the fuel tank. You gain access to it by removing the back seat, then opening the panel beneath the back seat. Replace the filter, screw the panel back onto the floor and the job is done....

Remove air intake from throtle housing.Spray carb cleaner in and around the butterfy.Leave to evaperate then replace the air intake pipe and start.

Fuel filter is under back seat. Remove back seat and there is an access panel in the floor. The fuel pump is also visable.

The trouble code P1128 is for a faulty mass air flow sensor or MAP. This is a common problem with 1999-2000 Accents. There is air leakage within the unit and/or the hot wire in the unit is badly contaminated. A bad MAP will cause the vehicle to bog and loose power.

I did some research because the P1128 is an odd code for Hyundai and I couldnt find a lot of information on it, but I found two things that may help and neither point to the fuel pump.

1. P1128 in Hyundai refers to the Mass Airflow Sensor or MAF being defective.
2. There is a TSB from Hyundai, TSB 01-36-022, but I wasnt able to ascertain if that was a specific TSB for the MAF or if it was information on how to test the MAF or some other information.

P1124 seems to be a related code as well but I could find little on it. P1124 in a Subaru is an issue with the Throttle Position Sensor or TPS, but I could not confirm that for Hyundai.

My first suggestion would be to check your air filter and if it has not been changed in a while or is really dirty, then change it as a restriction in air flow might be mistaken by the computer as a problem with the MAF.

For the 2003-2005MY the fuel filter is incorporated into the fuel pump assembly within the fuel tank.
