Default 97 LS cranks but won't start, help!

Only upgrades are Intake and Exhaust...

My car now has spark, battery power, and the smell of fuel. timing belt is in tact and cam gears are lined up with "Up" parrallel to each other.

The car turns over and cranks strong, but never seems to want to fire to get it started. The exhaust makes a slight popping sound, occasionally a louder backfire when I try to start after not starting for awhile. I just noticed that the PCV valve is broken and I will replace in the morning.

My other concern is that the car is not throwing any codes, so I am taking into consideration my ecu may be done for. Is there a way to test it, also, would resetting it have any beneficial value? Thanks in advance...
