93 Rodeo cranks but won't idle. Help!

Hi. I'm new here, so thanks in advance for any help. About 1 week ago, my wife went into the store, came back out and the Rodeo woudn't start. It turns over, sputters for 1-2 seconds, then stalls. I've changed ignition coils, plugs, wires, timing belt, PCV valve(which was broken), checked timing, checked in tank fuel pump, cleaned EGR valve, replaced IAC module and there are no trouble codes. Please help. I don't know where to go next and I can't afford to keep buying part after part.

How is your fuel pressure? There is a schrader valve under the hood that you can easily access to verify that your fuel system is being pressurized.
