Can you hear the pump priming when you turn the key everytime? If so could it be a fuel regulator valve? Just a wild idea but maybe your just not getting enough pressure to the TBs? But you'd think something more would happen than just cranking. Assuming the basics have been covered like spark and compression and such?
