2000 MX-5 Miata Won't Start

Okay so...

I just bought a car from a kid. Really good deal just based on the price he
gave me and the excellent body condition of the car. For reference, I rebuilt a
1992 NA Miata a half year prior to this so I thought I had a good grasp on
fixing this.

Turns out however I don't really know why this thing won't start. Perhaps
someone will have an estimation of what I can try.

So the kid had this car for about a yearish, judging by the DMV paper work I
got on it. He said recently that he attempted to 'fix' the cars engine bay fuse
box because the guy he bought it from had apparently 'modified' it to some
degree. I don't know what said modifications were, however after removing
and replacing the car would not start. And before anyone asks I know this car
is not stolen. I have the proper verification that it is not.

After some more tweaking he tore apart the fusebox and gave up, selling it to
me for a good price. I put back all the fuses and ensured the wires were
okay. Car does not start.

Fuel pump actuates (I can hear it).
Power comes on, Lights and chimes work.
Clutch safety works.
The immobilizer light doesn't come on (I don't have an original key)
The Cylinder turns to full run position.
I checked timing and everything is in place where it should be.
(161k Miles on it)

Yet when I turn the engine over, the engine spins for one single second
before it stops. Holding the starter for longer will result in a loud popping and
a smell of something burning.

I need some help ASAP thank you.
