Hi Anonymous, this model requires both plugs remain inthe heads when checking for spark you can use a third plug to check spark, don't forget to ground the threads. If you still have no spark get out your test light and check for continuity in the ignition circuit you could have a bad wiring or component connection, make sure all connections a clean and tight. Have the ignition coil and ECM tested, try pulling up trouble codes go to www.fuelmotousa.com/harleycodes.html If your going to throw parts at it start with the CPK sensor. Good luck

Hi Anonymous, if your FXDWG has a Crank Position Sensor the you need to leave both spark plugs in engine and check spark with a 3rd plug. If you still get no spark change plug wires and plugs. Please visit website below for more clues:

Hi Anonymous, when checking for spark the CKP needs to measure the compression bump in order to send the correct signal to the ICM/ECM so always check for spark with either a third plug grounded or lift the end of the plug boot 1/2 " off one of spark plugs that are in the head. and the usual suspects are:
1. Fuel tank empty
2. Fuel supply valve turned off.
3. Fouled spark plugs.
4. Engine flooded with gasoline as a result of over use of enrichner.

01 dyna wide glyde no spark


Hi Anonymous, if you have a CKP sensor it needs compression to send correct signal to the ICM/ECM, make sure both spark plugs are in heads and use a grounded third plug to check for spark or hold spark plug cable close to spark plug in head. If still not getting spark the usual suspects are:
1. Fouled spark plugs.
2. Battery voltage below 8.7 volts, loose or broken battery cables especially ground cable to frame.
3. Loose connection at ignition coil or plug between ignition sensor and module.
4. Spark plug cables in bad condition, shorting / leaking, spark plug cable connections loose.
5. Faulty ignition coil or ignition / electronic module
6. Failed CKP, CMP, MAP or BAS sensor.
7. Faulty ignition switch.
8. Security alarm failing to disarm.

Will not start


I'm telling ya, since harley went to all this computerized stuff on the bikes, they're getting just like our cars got. It's getting to where you can 't work on them yourself anymore.

The ignition circuit has it's own fuse now. Since Harley went to fuses instead of circuit breakers, the slightest thing and you're down for the count. With circuit breakers, you could short something and a few seconds later, you were ready to go again. These days, you've got to find the fuses and check all of them. I don't know where your fuse box is located on the bike. The header says you have a 2000 Road King. If that's right, I think the fuse box is under the seat or the right side frame panel. That's what I'd check first.

Of course, you know that you've got a compression sensor on your engine. If you take the plugs out of the heads and put them in the wires, you won't get a spark. Take the wires off the spark plugs but leave the plugs in the heads. Put another set of plugs in the wires to check for spark.

If you'll contact me directly. I'll scan a troubleshooting chart and send it to you. It may or may not help. Seems Harley changes stuff as often as the Japs do now. Contact me directly at my personal e-mail wd4ity at bellsouth.net Remind me of what you need, ignition system troubleshooting chart.

Good Luck
Steve
