93 chevy s10 2.5 tbi L4 cranks but wont start

What is your question?

Had a water pump go bad truck overheated and died. Ever since then it will crank but not start. Checked fuel pressure(11.3 psi) replaced fuel filter just to be safe. Still nothing. Proceeded to give it a full tune up (plugs, wires, dizzy cap and rotor, EGR, air filter, battery and cables) on top of replacing my radiator, water pump, thermostat housing and thermostat.(as advised by my local shop) STILL WONT START but cranks like a champ and sounds like it wants to start.....any help or ideas are welcome I'm all ears as I'm stumped.....

How long has your 1993 Chevrolet S10 had this problem?

A few weeks
