Changed my battery I must have turned ignition switch on. Engine did not start again.
checked the ECU, LED self diagnosis system.
no flash. Book (Haynes) indicates inspect number 5 fuse.
There is a caution elsewhere in the book to prevent damage to the ECU, the ignition switch must remain off when disconnecting or connecting power.
I cannot locate fuse number five. I have checked both fuse boxes under hood and inside. They do not identify a number 5 fuse.
any ideas? Thanks

Thank you! I looked and fuse is good. I am thinking about buying another ECU at salvage yard to test if I get same results.
Thank you again.
