I have no fire in my front cylinder - 2002 V Star 1100 - I have moved the wire and plug to rear cylinder coil and they worked. I have also unplugged the coil for rear cylinder and plugged them into the front cylinder coil and it worked. SO I conclude that the plugs wires and coils are fine. what would be the next step for troubleshooting this problem?
Any help would be greatly appreciated. I ride daily all year round but this is the best season for riding in Las Vegas and I am going crazy stuck going to work every day in my Hyundai
PLEASE RESCUE ME FROM Hyundai HE%#.

Thanks
Aerolon

Bling help

Areolon,
My 1100 V Star CD seems to have stopped working, so I am in the dark. I am a little confused on your checks. If you swapped the leads from the ignition module front to rear and the problem did not move?

Be sure the problem is not really a fuel problem. gummed up jets are much more common. If so try some Sea Foam. Run the bike in the dark and look for a spark. Then look at the plug while cranking and be sure there is no spark. Maybe pull the wire off and use another plug for a test.

As I see it if the problem is ignition and not in the plugs, wires, or coils then it is, power to a coil, ignition module, or crankshaft position sensor. In my liner book last step is replace ECU. I think on the V Star ECU is Ignition module. The most expensive part in the string is the module so is last resort. I understand ignition modules are pretty reliable and seldom fail. Double check everything else. In my bike there are fuses for each coil. The coil is triggered by the ignition module. The timing for firing comes from the crank shaft position sensor. Yours may be just called pick up coil.

Good luck.
Dave

No Spark?

If you are sure it is spark, then check for power to the ignition coils with the key on. If you have power to one and not the other, easy fix. Blown fuse or bad wire.
If you have power to both coils, then turn the ignition back off and get an Ohm Meter and check the coils. With the connector unplugged the ohms from one post to the other should be 3.57-4.83 ohms.

While you are there it would be a good time to OHM the ignition wires also. If one wire is a lot higher, replace them both.

next check from the secondary (Plug wire end) to the connector that the orange/gray lead connects to. The resistance should be 10.7 to 14.5 K(thousand) ohms.

If the two coils are significantly differant, then replace the bad coil. if not then the problem would lie in the ignitor assy because your pickup coil signals for both cylinders. It cannot drop just one. It either functions or does not.
