Any suggestions?

Problem started when I took my motor out to put in a skunk 2 manifold.
I asked around and found out I didn't need the egr valve so I doesn't put it in.
That being the case I thought I might as well wire tuck some things.
I ended up unwrapping my engine harness and taking out the wires leading to the egr.
The harness was also from my 01 sh so I took out the wires for the atts.
I also moved the IACV to the back of the manifold so I had to extend that sensor.

The other problem happened when I was checking the ground for alternator and forgot to disconnect the battery. Ended up blowing the battery fuse but replaced It with a spare one.
I've been taking my wire harness out to check to see if anything I spliced came loose and that still wasn't a success.

Now the car has been sitting in my garage for 2 months because I can't figure this out.

Other facts about the car: 2000 H23A PDE stamped running a p28.
