Go through the engine bay harness piece by piece. There's some chance one of the sensors to do with the ignition isn't getting the right input. When you say you've got fuel, do you mean from the fuel line, the fuel rail, or the injectors? I forget just how the injector solenoids "fire" but that's another thing it might be

sensors should bring up engine light and with this you can check what codes are up.
Does it seem like it is flooding??
Check and make sure that the fuel pressure regulator is functioning correctly.
Make sure you have power to and through your EFI relay. If you have power through your relay check the Red wire to your injectors and you should have power here also.
Check for continuity of your injector signal wire from your ECU to your injectors, signal wire is the light blue wire.
See how you go with that and let us know.
Cheers
 

What's the difference between understeer and oversteer?
Understeer is when the driver is scared.
Oversteer is when the passenger is scared.

Still alot you can check before you need to go get a new engine buddy.
How did you check the fuel pressure reg??
Had a V6 doing the same thing the other day and it turned out being the fuel pressure reg.
If you try starting it with your foot flat to the floor will it start??
