    this sounds like an infamous fuel pump issue. no way for the computer to detect no fuel flow. so do a pressure test, and turn key to run. do not start the engine and hear for a buzzing noise. it should last a few seconds. these codes together on this year is often fueling issues oops posted in wrong spot. sorry
