Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello. IT sounds like you have either a damaged wire shorting to ground, or your fuel pump is beginning to go bad, which is drawing too much power and blowing the fuse. I am leaning more toward a shorted wire. Inspect all the exposed wiring under the hood. O2 sensors, etc. Check the wiring to the fuel pump also under the back seat.
If you need further assistance please feel free to ask. If I have answered your question to your satisfaction please remember to rate me. I greatly appreciate it. You can always followup at no charge after rating
