Q: Fuse keeps blowing

asked by on

The fuse for the fuel pump keeps blowing at random times.

Fuses are a safety device that are supposed to be the weakest link in the electrical system. They are designed to pop open when the amperage exceeds its rating. I would suspect that the positive wire feeding the pump or the pump itself is shorting, causing spikes in the amperage. Have a certified mechanic, like one from YourMechanic, test the electrical system and possibly change the fuel pump or wiring.
