Message	big +1. Just becuase they have power doesn't mean they're getting the signal to fire. When the key is on they both have 12v constant. The ECU grounds the injector for a split second to trigger it to fire. The ECU sends a secondary voltage through the PTU to induce a high voltage in the primary of the coil pack and trigger it to fire. So if they have power that's only half of it. Do like woody said.... VISUALLY check for spark. Then check for fuel by listening for the clicking of the injector when the engine is running... or pulling the spark plug after its been running/cranked to see if its wet/smells like fuel.
