Answers :

P1338 - Fuel Pump feedback circuit low/high voltage. This is indicating that your fuel pump is either getting too much voltage or too little voltage as is sensed by the fuel pump control module. Now, this can be caused by either bad wiring connections or a battery not charging causing low voltage. Should read 14 1/2 volts if charging at 1500 rpms
