I need to do a compression check on my Catera since I found water in the well of spark plug 1, with the plug still in it. I fear that I might have a very serious issue such as head gasket or cracked head, etc. To do the check, I need to remove the fuse to the ECU. I am certain it is under the hood, but I cannot find it. I believe it is an 80 amp, V4. Can you tell me where it is located?

you don't need to do that just do a compression check or have a pro pressure check coolant system
