A blinking 'ck eng' light means that cat damage is possible if you continue to drive like this. It is explained in the owners manual. Severe cylinder misfire means unburned fuel can reach the cat and destroy it.
Are you getting a P0301 fault code? This would narrow it down to a single cylinder and ease diagnosis.
An ohmmeter will confirm wire continuity, but can't guarantee that the wire won't leak (arc) or otherwise breakdown under high voltage. Spark voltage soars under engine load. Any coil/wire/plug arcing seen or heard under briefly 'power braking' the engine? Stand to the side and not in front of the vehicle when trying this with a helper.
You could try to swap the #1 fuel injector with an adjacent injector to see if the fault code follows the injector if you suspect a fuel supply issue (too much or too little) to that cylinder.
You don't want to drive with a dead cylinder.
