RE: test an ignition coil?
put a driver in the coil wire put it close to a pice of metal and turn it over you will see the spark (dont touch the metal on the drive and do this some where there aint to much light) good luck...this is the old school way ...or get a volt meter

RE: test an ignition coil?
the ignition coli have 4 terminals to check if its ok you grab an ohmimeter and check the resistance betwen terminal a and c of the coil it shoul be betwen 0.7 or 0.8 ohms then check the betwen the secondary and the a terminal it choul be around 22,000 ohms if this its correct the coil its good
what you do next is with the car ignition on you check if you got batery voltage in the 2 primary wires of the coil if you got 12v the you hook a test ligth to the positive batery terminal and the other end in the coil signal then you try to start the engine if the ligth blinks but you dont have any spark the coil its bad if the ligth doent blink check the ignition distributor or icm (ignitioncontrol module) inside the distributor
i hope you fix your problem good luck
