on my 92 yota 22re my EFI fuse keeps blowing i cant figure out whats causeing it any ideas???

 

Common cause is an O2 sensor wire that has fallen against the hot exhaust causing the insulation to melt and the wires inside to short.

 

yeah thats happened before but i dont even have the o2 sensor hooked up the wires are taped and tied off to the frame could it just be from it not being hooked up?

 

I have the same problem. Just started in the last week or so. Was told by the dealer it could also be the EFI relay or circuit opening relay under dash. Mine blows fuse when I turn key to start. Thought it might be the fuel pump, but removed the circuit opening relay to test it, and problem is still there. Fuse went last week when wife was driving down the road. All relays seem to test ok. 95 x-cab 4x V6 auto. Any thoughts?

 

Make sure that your ground wire from the bat to the engine is first rate and check the ground wire for the efi circuits( located on the passenger side of the motor just below the aluminum air intake, about in the middle,a large wire bolted on). Good luck!

 

Did you ever get that fuse blowing situation fix. I'm having the same problem with the EFI fuse. Took mine to the shop, was there for a week. Problem was not found.

 

I'm having the Same problem. Did you ever fix the blowing of the fuse? Mine was in the shop for 1 week, they could not find it, maybe you can help. Thanks

 

Did you get your fuse problem fixed, having same issue with a 1995 corolla, not o2 sensor, changed the ignition switch, bit the fuse keeps blowing as soon as the key is turned to acc, before the crank up

 

You absolutely sure the EFI fuse blows when you turn switch to ACC? Please see signature.
