If you have narrowed it down to that one fuse by doing a drain-test. Then you need to check that circuit and see if there are any bad relays, then Replace them.

Take a test light and put it on each fuse. If it lights up that fuse (and everything past it) is drawing power. This will help you narrow down where the drain is.

Going to check all the fuses, and got a new relay in the mail today. Diving into it on saturday. Will let you all know if I figure something out. thinking I may have a grounding issue as well.

Alright, well a buddy of mine came over and we spent a few hours on the problem. What we figured out was the ecu was in diagnostic mode and that was what was making the efi relay engage. We messed with the diagnostic port and no more clicking relay. Hoping this fixed the issue. will update tomorrow. And I figured out why the cel and vsc lights were on. the cam sensor wasnt plugged in all the way

So you replaced the EFI Relay ? Did the voltage drop decrease with the new relay?
What is your voltage drop with everything plugged in? and then what is the voltage drop with the ECU fuse removed? If it's really the ECU, i wonder if you can get the dealer to reprogram the ecu ...

Alright, back again and I think I have it figured out this time. I believe the culprit to be a small switch that is attached to the ignition. I have read on a different forum where I guy had the same issue with a toyota camery, they use the same ignition so I ordered the new part and will update when installed
