Have you pulled out the injector to see if it is cloged up,when a injector goes bad all it will do is drip gas into the cylender,a bad one may be the problem.

switched injector with another cylinder no change still misfire on number 1

are you sure the plug wires are in the right fireing order.,it has a coil pack right? that could also be your problem,where the plug wires plug into.

NO on ECM,that would affect all injectors,maybe a broken piston ring causeing the dead cylender.
