In the 2003 Dodge 1500, you can locate the fuel pump relay inside the central junction or fuse box within the engine bay. It should be situated on the driver's side near the front by the firewall. This relay is responsible for managing the electrical power going to the fuel pump. You may need to replace it if you encounter issues such as the engine not starting, stalling, or if you don't hear the fuel pump when you turn the key to the "on" position. A complete failure of the relay can prevent the engine from firing even though it will crank. If it's failing intermittently, the car might stall but then start up later. The cost of replacing the relay is typically less than $20, and owners can refer to the owner's manual for instructions on how to do it themselves.
