Assuming you have spark, if starting fluid didn't get it started then spark timing is off.

Distributor(and cam) turns at 1/2 the speed of the crank, so there are 2 TDCs for each one revolution of the distributor.
TDC compression stroke << the one you want when distributor rotor is on #1
TDC exhaust stroke

Put crank on TDC
Distributor rotor should be on #1 or #5
Pull up distributor rotate rotor 180deg(1/2 turn) and reinstall.
So if it was on #1 then put rotor on #5 or visa versa

If you didn't pull the distributor, that should be okay. Did you knock the smaller ground wire loose near the battery. It has a push/pull connector about 1 foot away from the battery and heads for the airbox to enter a wiring harness.
