Topic: EFI Fuse Blowing

[mudmaster]

2000 4Runner, 3.4. As soon as the ignition key is turned it blows the 20A fuse under the hood. Anyone have any ideas what it may be?

It had a small fire 2 weeks ago that burned/melted some EVAP system vacuum hoses and some wiring. I just fixed/replaced all of that. It was starting and running fine prior to me fixing it, but was throwing a code for EVAP sensor.

Yes its a wire grounding out.. most likely check this around that fire.. check wires to all 02 senors.. things like that.. its gonna be small and gonna take time. My dads jeep did the exact same thing ended up being a wire going to an o2 sensor..

blahhhhh
