Default cyl #3,6,7,8 not firing. spark but no fuel

had the engine out of the car for 2 weeks just to clean everything up/paint real nice. started it up today and i could tell not all were firing. touched the headers right away and #3,6,7,8 were cold. have spark. has to be the injectors right? do these cars have sister injectors? if so, which ones? can it be a bad ground even though the other ones are pulsing fine? any other thoughts? can i used a test light for a noid light or do i need one with specific resistance?

YOU NEED TO USE A SMALLER WATTAGE bulb other than a test light
