Hi I have 2001 ram 1500 with the 5.2L and I’m not getting power to my fuel pump . The relay is new and getting power but the fuel tank sending unit connector is not. The gas gauge is working and the fuel pump is new. What can I do to fix this

 

When you turn the key to 'on', do you hear the fuel pump prime at all? It should run for a few seconds and then stop. Have you checked the fuel pump to ensure it's good by ensuring it's grounded and getting 12 volts to it on the appropriate pins/wires?

 

Also, keep in mind, your pump will only see power for about 3 seconds, unless the PCM sees the engine turning. (crank sensor signal)
