Car won't start!

here is some background on my car.
1987 NA 5 speed. Bone stock.
This car ran poorly even since i bought it, but didn't care because i was gonna fix it with all the parts i have.
Now i have given up and im trying to sell it.

I went out to start it today, and it will not start.
Here is what i have done.
-It has fuel and spark
-checked the plugs, they are ok, a little wet and good spark
-ran the codes, everything appears ok(maybe it's because i checked while the engine was cold)
-checked all fuses and fusable links
-i see an rpm signal when cranking
-Battery is good + i kept it on the charger to make sure it was full of power.
-Tried adjusting the timing on the distributor(also tried my spare distributor)
-all injectors are firing
-fuel pump primes and comes on, but i have no way of checking the fuel pressure

Before i had this problem, the car started fine everytime, but it sputtered lots( like a miss) and it backfired alot when you revved it up.

Any input is greatly appreciated, it was running a few days ago and now nothing, just cranks over and smells like gas.
