Hello, did you ever check fuel pressure? If you have TBI, do the injectors spray gas, that doesn't mean you have good pressure, but, it shows the injector/s are pulsing. If you do a lot of cranking and the injectors are pulsing, you may flood it.

Any codes, do you have spark at the plugs?

The thing that I don't like about these forums is that the original person with the problem never responds AFTER they have their problem fixed. So I'm sitting here at 3 in the morning reading about TBI injectors not firing hoping to find an answer but just more dead ends.

Earlier you were asked if you check the fuel pressure -You need to check the fuel pressure EFI system don't like low fuel pressure also check the injector/s solenoid resistances if okay could be very well be an ignition system problem.
