Hi, Don and the usual suspects are:
1. Fouled spark plugs.
2. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
3. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
4. Loose connection at ignition coil or plug between ignition sensor and module.
5. Spark plug cables in bad condition, shorting, leaking, spark plug cable connections loose check for spark leakage in the dark.
6. Faulty ignition coil or electronic control module.
7. Faulty CKP, CMP, or BAS sensor.
8. Faulty ignition switch.
9. Tilt sensor needs a reset.
10. Security alarm failing to disarm needs reset

1. #1 test. Obtain a 12 volt circuit tester, the type that looks like an ice pick with a wire coming out of the handle. With ignition on, hold the tip of the circuit test against the post of the coil, the post that is marked with a + The light in the tester should light up, meaning you have battery power. If you don't have electrical power there, trace back to battery to find out why. If you do have power at that point
2. Moving the the opposite side of the coil and place the tip of the tester again the post marked with a minus. With the key on, crank the engine. The light in the tester should flash. These 2 test have just tested your battery and ignition system. Bill

Rear cylinder not firing


The first thing I would do is replace the spark plugs again. You can foul a plug and it will cause you more problems than you can ever imagine. I see you have done all the logical things that I would recommend but I did not see you have replaced the plugs after the 200 miles. You would be surprised at how many times a $2.00 part can cause fits beyond belief.
