Default could it be possible

could it be possible that a loose ground wire for the brake and tail lights could be causing my fuel pump fuse to blow,i do believe that they are ran on the same circuit?

There does not appear to be anything common between the fuel pump and the tail or break lights. Fuel pump is fuse 21, break is fuse 25, hazard is fuse 20, signal is fuse 6 and the tail light is fuse 2.

you may have a bad fuel pump causing the cricut to overload try using a higher amp fuse see what happens

Your downstream O2 wiring may be grounding out and blowing the fuse pump.

I would not recommend a larger fuse it could easily cause damage to wiring or other components. The same fuse that feeds the fuel pump also supplies the PCM, injectors, O2 sensors, coil pack and alternator fields. As mentioned above the downstream O2 wiring may be faulty as they sometimes come in contact with the exhaust system. Also is the check engine light on? (Hmm! a blown fuse may disable that too as it supplies the PCM). Try unplugging the O2 sensor and see if the fuse still blows (it should still run but will give O2 codes).

Does the fuse blow immediately or after the car has run for a while? If it blows immediately you probably have a short somewhere, if it runs for a while and then blows I would suspect a faulty part (fuel pump?).

Unfortunately, I believe that pulling or blowing this fuse also resets PCM engine codes and light.

just from experience and other simular post here, I would check your o2 sensors, the harness for one of themhas more than likely broke from its mount and has laid on something causing a wire to rub bare, mine was laying on the axle.
