To determine if a 1993 Chevy 305 coil is bad, check for symptoms like engine misfires, rough idling, or difficulty starting. You can also test the coil with a multimeter; measure the primary and secondary resistance according to the specifications in the service manual. If the readings fall outside the specified range or if there is visible damage, the coil is likely faulty. Additionally, if you notice a weak or absent spark when testing with a spark tester, the coil may need replacement.

symptoms are: you can hear the engine missing, spitting and sputtering, loss of power...you can tell if it is a coil pack by unscrewing the spark plug that it connects to coil pack. when you look at your spark plug it should be a light grayish, white..this means the coil pack is working....it is best if you do this with new spark plugs, because your spark plugs could be bad. but you do this process until you find a bad plug then, that coil pack probably is the bad coil pack.
