Why does my fuel pump fuse keep blowing?

Why does my fuel pump fuse keep blowing? Because you have a short to ground, causing high current draw. The most likely cause would be a failed pump. But, it could also be a broken wire or something else in that circuit. Click to see full answer.

Where is the fuse on a fuel pump?

It is often found in the fuse box located in the engine bay and functions as the primary electronic switch that controls power to the fuel pump. The fuel pump relay is usually controlled by the ignition or powertrain control module, and when switched on, will provide current to the fuel pump so that it may function.

Why does my fuel pump keep making noise?

Belt or bearing going bad. The noise you are hearing is coming from one of the bearings of the tensioner pulley, water pump, alternator, A/C pulley and possibly even the power steering pump if the noise is a bearing noise. Sometimes just a belt noise…
