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.

The fuel pump is vapor locking, common problem in high temp/altitude states. Call the dealer and see if campaign t-13 applies to your car, if the car was originally sold in a low altitude state, it won't apply. I recommend the fuel pump be replaced with updated fuel pump sub assy.

Remove the MAF sensor and carefully clean the sensing diodes with some solvent and a q-tip. These codes are commonly caused on this car by a dirty MAF that does not see the air entering the engine so fuel is not added by the computer. Then the computer sees that the mixture is lean by looking at the exhaust gas oxygen (sensor) content and it sets a code because it can't trim fuel delivery to the correct level as the MAF signal has more authority.

Let the vehicle warm up for 10 minutes at idle and shift it to Reverse if the RPM bumps up thats fine but if it dosent then replace the IAC idler air control valve.
