To paraphrase the responses
(1) Install new plugs
Use a Multimeter to measure resistance (ohms) for the next steps.
(2) Check resistance between the two spark plug wires on each coil, 15k-22k ohms is ok.
(3) Check resistance between the two little wires on each coil, 2-5 ohms is ok.
(4) Set meter on DC Volts and measure between each of the two small wires on each coil and negative terminal on the battery with key on, should be near 12 volts on one of them on each coil.
If all that is fine, then check the ground wire between the igniter and ground.
After that you are into the ignitor checks and I don't have a manual for that one, so ask WiredGeorge
Explanation for the specs:
The reason for the 2-5 ohms is that not all meters are the same, and if the coil is shorted it will have less than 2 ohms, and if open then considerably more than 5 ohms.
If the coil has between 2 and 5 ohms resistance then it will work.
Same deal with the 15k to 22k, maybe not according to specs, but if it falls within that range it will work.
Don't get hung up on exact numbers
