It sounds like a bad air flow meter to me. I had one go bad about 10 years ago and it drove me crazy trying to diagnose it. I replaced pretty much everything first but ruled it out early so never tried it. I had no spark and no fuel but I had power everywhere I should have. Swapped it out and it ran fine. Try that. If it isn't working properly, it may not send the ecu the necessary signals to fire the coils and it won't trigger the injectors either. Aside from the ecu, the air flow meter is the only other thing common to both the ignition and fuel systems.
