2000 Saturn SL2 cranks but won't start after intake cleaning

My car ran but was bucking at low throttle, I cleaned my EGR, then cleaned
my intake out, new gaskets of course. I also disconnected, and applied
dielectric grease to all electric connectors I saw, including both PCM wires,
and the one to the fuse box(bolted). I also soaked my injectors in Barrymans
for cleaning. When I went to attach my fuse box I realized from it sparking I
forgot to disconnect my battery until that point. After I get everything on, I turn
on the ignition and sit a while for the fuel to pressurize, and when I turned to
start: about 4 engine cranks sounded "normal" then it started cranking as if to
start with slight vibration. I agitatedly kept the starter going 15seconds, filling
my garage with rich smelling smoke. After this I had realized I'd leaked 50%
of my power steering revisor via a hose I pulled too hard. Could the power
steering pressure sensor cause this if leaking this severely? Could it be my
ECTS maybe, I changed my antifreeze about a month ago and the old fluid
was nasty. I had the antifreeze empty about a week from this job, thus leaving
the coolant sensor dry; they're usually crappy with these models. I also
wonder if it's my crankshaft position sensor because the car would only buck
when it got to operating temperature.
