Hello and thanks for the question...I'll try to help.
 If you have all of the things listed, it should run.
I would recheck all of them:
Use these links:
Firing order:

Also, you might wnat to change the oil and inspect it...It is most likely fuel saturated from cranking the engine over and not starting.
Also, remove the dist. cap and crank the engine over...does the rotor turn? If not, I would suggest that you check your timing chain.
Next recheck fuel pressure at the schrader valve(located on the fuel rail)... Just because you hear the pump running doesn't mean that it is pumping the correct amount of fuel or pumping at all. The spec I use is with the key in the ON position and the engine off you should have 38-41 PSI.
Hope this helps
