Default plenty of spark , still no fire

the other day my distributor blew out on my hatch. so i replaced it, and now im getting spark agian, but the car will not fire . i checked my fuel pump, its also fine. i have fuel to the fuel rail. its acting like no fuel is passing the injectors. which would make sense to me, but my main question is, if my fuel system was perfectly fine the day my distributor went out, why would the fuel not be getting to the cylinders now???

that would make sense, but if a spray a tiny bit of starting fluid in the intake, it starts fine. . if the firing order was wrong, it prolly wouldnt fire even with the starting fluid??

Can you hear the fuel pump prime the system for a few sec. when you turn on the key to run, [not start]?
If not, check the fuses for the PGM-FI Main Relay, there are 3 of them.

Turn ign. on and test for 12V at the injectors, wire that is the same color on all injectors is the power lead.

If there is power at the injectors and the fuel pump primes, check ECU/ECM fuses. 94

resistor box is getting power, and i did actually check the thermostat ground, cuz i thought about that so i tried and still nothing i checked my distributor on my friends bseries and it started his car fine. so it has to be something else with my car. i checked over my harness for any loose connectors or possible bad grounds, and everything is legit.... and i tried the other ecu's again to make sure it wasnt just a one time thing.. and no luck ????????? im bout to burn it to the ground.. if anyone has ever had a similar problem please help me out, ive never had this problem or came across it with any other car and its nerve racking...
