So, my car wouldn't start for the past couple of days. I traced the problem back to a short circuit on the efi no.1 fuse. After spending hours on alldata.com trying to find out exactly what that fuse protects, im losing my patience. Does anyone know exactly what efi no.1 controls?

 

this is for a highlander but toyota is a toyota hope it helps

efi fuse will go to efi main relay. you can check the relay by applying power to its coil and listen for a clicking sound. then check for continuity between the other pins with power applied to the coil and without power.

 

thanks guys, i will look at that highlander page, ummm i found a short in the ef1 connector, its a white wire so i'm trying to trace where that goes

 

Yo thanks shogun for that highlander link, I didn't pull a gel, but there was a short in the secondary 02 sensor and that's what kept popping the efi1 fuse. The no.11 pin on connector b1 had a short, that's the power to 2nd o2

 

your welcome, glad it helped. all of this sounds like chinese to me
