A weak ignition coil will give you weak spark

Testing a coil for resistance is not a very good test. The coil is not under a load. You can give it 12 volts with a jumper to make shore your not droping voltage on that line. If it can't jump a spark tester gap or @ least a quarter of of an inch gap and its not bright the coil is week.
