I don't believe the 91 MR2 engine had a knock sensor.
If so, you have several problems.
First off, your CEL should be on, if it's not, someone disabled it. This is bad.
Second, the engine is going to run like crap because of it.

Your EFI fuse blowing might have something to do with the first thing, and your lack of power something to do with the second thing.

Basically, you need a new engine [92^ from a Celica/Camry or 93-95 from an MR2].

Now if it's not a 91 engine, we have to start over.
