Here are some symptoms of a bad fuel pump relay:
* The car cranks but does not start.
* The car starts but runs rough or stalls.
* The car hesitates or jerks when accelerating.
* The car loses power while driving.
If you experience any of these symptoms, it is important to have your car diagnosed by a qualified mechanic to determine if the fuel pump relay is the cause. A bad fuel pump relay can be easily replaced, and the cost of the repair is typically not very expensive.
