Lightbulb gas and spark but still no start?!

ok so i've tested both. the injectors are shooting out perfectly and i took out a spark plug and grounded it on the a/c compressor and it sparked fine! what is up? i currently dont have any coolant in the system is there a sensor that wouldnt let it start cause of that? i even sprayed starter fluid into the TB and then again right into the spark plug hole! HELP!

Crank sensor. Check to see if the rotor turns also.

i saw this thread and thread searched and some guy had the same problem. but it happen differently. his problem was fuel pump went bad. But seeing as how a fuse to the comp blew...it might have blown other fuses. Just throwing my $0.02 in
