* To troubleshoot the fuel pump on your 2002 Dodge Dakota, you can start by checking the fuel pump relay. The relay is located in the engine compartment fuse box. If the relay is faulty, it will need to be replaced.
* If the relay is not the cause of the problem, you can then check the fuel pump circuit. The circuit consists of the wiring that connects the fuel pump to the battery and the fuel pump relay. If there is a break in the circuit, the fuel pump will not receive power.
* If the circuit is not the cause of the problem, then the fuel pump itself may be faulty. In this case, the fuel pump will need to be replaced.
