So what's the symptoms? If the engine doesn't start, did you check for spark or just get hung up on the injector issue?
If the timing belt is off by one tooth, the "Check Engine" light will be on. If it's off by two teeth, the computer will shut the engine down by turning off the Automatic Shutdown relay. The ASD relay feeds battery voltage to the coils, injectors, and fuel pump or pump relay. If the belt is off by three teeth, the pistons will hit the valves.
If the timing belt is installed correctly, and the engine still doesn't start, remove the camshaft sprocket and inspect the dowel pin. When they break, the camshaft slips a little on the sprocket. Even though the sprocket is in time, the cam, and the cam sensor on the other end of the cam, are both late, just as if the timing belt was off. The common symptom of this problem is a spark every now and then and only the two center injectors fire intermittently.
