Engine Mechanical problem
2003 Toyota Corolla 4 cyl Two Wheel Drive Automatic 145, 00 miles

While driving the car it turned off and will not start. The EFi fuse was burned out. I was told it was the fuel pump. I replaced the fuel pump and the EFI fuse, but the EFI fuse continues to burn out and the car will still not start. Any thoughts on what is wrong?

Do you

Well, that fuse supplies power to a lot of loads. MAF, Vent valve, purge valve, vapor pressure sensor, both 02 heaters, fuel pump. What you need is a good wiring diagram and starting unplugging things that are on that circuit.
