EFI Relay
Ok, So I am an idiot....I pulled the EFI relay fused to reset the tranmission like forum members have suggested, and I forgot to undo the battery first and turn off the car (I was listening to the radio) and blew the relay.....I feel really, really, really dumb. So my question is, how does one go about changing the EFI?

Are you talking about a relay or a fuse, they're 2 different things.

Sorry, the relay. The fuse is fine. I think I shorted the relay when I pulled the fuse with the car on.

What year? The pic below is a 4th gen...
This is a quote from another thread but it may help; "2) Remove the fuse cover by pushing in on the plastic latch. My finger is on the latch in the photo. The lid will release than it will lift right off.
3) Using the tool which "lives" in the fuse block remove the two fuses for 3 minutes or so. Then replace the fuses and cover. Turn the key to on, wait 5-10seconds and then engage the starter. That's it! The other thing is make sure the tires are serviced 32-35psi.

Sorry I somehow overlooked this question. I think EFI is as in Electronic Fuel Injection? I'm sure someone will correct me if I'm wrong.

EFI is Elec Fuel Inj, but it's a big system.
You want to change the entire EFI system, or some part, or what.

Where did you see the instructions to pull the battery first? I pulled my EFI fuse once but didn't unplug the battery. Also I know Chris posted in another thread ( Getting Chittay Gas Mileage !!! HELP !!!) and only mentioned to have the car off to do this.

Actually my problem was the car was on, not that the battery was connected; however, the dealership was actually the first to suggest to pull the fuse. They said to turn off the car and undo the battery to be safe. All ended well, but I still wouldn't do it with the car on again.
