Sounds like a regular compression test. It is very possible that it did bend a valve if the needle bounced around. Bent valves is usually a final conclusion for your kind of problem. Usually have to rule all other possibilities out which you have done with the ignition system. Kia and Hyundai's all have interference engines which basically means that piston and valve can contact each other if a timing issue where to occur such as a broken timing belt. Timing belts usually only last 100, 00 miles. At this point you may want to remove heads to verify.
