If your tail light is blowing a fuse everytime you step on the brakes there maybe a faulty or crossed wire. Have your mechanic check it out to be sure.

I have a 91 240SX and had a similar issue, my Fuel Pump had to be replaced.

An electrical short between the fuse and your fuel pump, I would replace the fuel pump first..

Disconnect the harness at the fuel pump and replace the fuse. If your fuse doesn't blow after turning the ignition on, you probably have a bad fuel pump, check it for shorts.

A live wire in the audio circuit is touching metal, or connected to ground in some way.

More than likely the fuel pump is going bad. Also check for a clogged fuel filter which will cause the pump to overheat and blow the fuse.

You may have a problem in the pump. Take it off and check .

You have a bare wire that keeps shorting out & blowing the fuse, I had the same problem. The wire is the one that runs from the fuse to the fuel pump. The casing has melted away and now the wires are touching.

remove fuel pump fuse. then start engine it will stall when fuel runs out change filter then replace fuse.

The fuel pump fuse is located in the fuse box. The fuse box can be found in the engine compartment. The location of the fuel pump fuse is listed on the inside cover of the fuse box.

it has a short somewhere in the electrical line

Either you have a loose cable, a short somewhere or the wrong fuse. Do not change fuse rating other than what it specifies to.

There is a fault associated with the fuel pump. You may need a new one, or it may mean a severely clogged fuel filter.

Fix the fault blowing the fuse.

it is in the fuse block and is used to protect the fuel pump and wiring to the fuel pump from being overloaded and melting or catching fire by detecting to much current and blowing (melting) before the wire harness or pump does.

The fuel pump is probably faulty, but there could be problems with the wiring or the relay, if one exists.

Short in wiring, relay or pump? internal problem in fuel pump.
