Low fuel will not create a black rich condition.
Disconnect your fuel pump connector so you do not flood the engine anymore and...
Do you have spark? Remove the coil wire from the cap, hold 1/4" from a good ground and crank the engine for 10 seconds, is the spark strong and consistant? If no diagnose and correct the no spark condition. If yes recheck at a spark plug wire, if no spark diagnose and repair, if yes....., count 1-2 sparks as no spark.
Verify the Cam timing is 100% correct and get the distributor set properly, it will be when the intermidiate shaft is properly aligned and the distributor housing is parallel to the block.
Check fuel pressure, is static pressure 53-57 psi and holding steady?
Are the injectors pulsing are staying energized?
Check MAP and CTS circuits.
FYI, smell the oil, if it is fuel diluted you may want to change it before cranking the engine for prolonged periods, fuel diluted oil will wash down the cylinder walls that is why during diagnostics for a no start other than the fuel system you need the fuel system disabled.
