Heidi Edgmon your Code 5-4 is the code for Fuel Pump Circuit Voltage Low which would explain your voltage being at 2V. I would start by trying to direct to wire the pump to a 12V line to see if it runs. After that I suggest you check the wiring for a possible bad connector/broken cable/poor ground.

Take a look on here for the fuel pump wiring test. Let us know what you find out.
