Why is my Sportster not getting a spark?
A failing crank position sensor can cause a problem like yours. A bad sensor will sometimes fail when heat is introduced and begin working again once it cools. If/when this occurs again, turn off your fuel valve right away to see how much gas is in your float bowl. Open your gas cap and listen for a possible vapor lock condition.
Where is the ignition sensor on a Harley Davidson Sportster?
The crankshaft position sensor location. The I.C.M. (ignition control module) was used on Sportsters before the year 2007. After 2007, the module became integrated into the E.C.M. (electronic control module). These modules contain internal circuitry found on most computer motherboards.
What does a crank position sensor on a Harley Davidson do?
A Harley-Davidson motorcycle engine may sputter and hesitate when a crank position sensor (CKP) starts to fail. The CKP sends data to the motorcycle computer data center about the position and speed of the crankshaft, the ignition and fuel injection.
Can a failed crank sensor cause no start?
The thing to remember about having a failed crank sensor, is that if you have spark or fuel injector pulses, the crank sensor is OK and not the cause of your No Start Condition. The crankshaft position sensor, on your 4.8L, 5.3L, 6.0L GM vehicle, is a Hall-Effect three wire crankshaft position sensor.

How to check spark plugs on Harley Davidson Sportster?
Insert a spark tester into the wire and attach the tester to ground. Remove the fuel pump fuse. Refer to the article Fuse Box Information for fuse locations. Crank the engine and watch for spark. If spark is consistently present, the problem most likely lies with the spark plugs and you should continue to Step 2.
Why is my crank position sensor not working?
The symptoms of a faulty CKP worsen when the bike is revved up. Contaminated fuel or bad spark plugs can also cause similar problems, so you may need to test the crank position sensor.

How does the ignition work on a Harley Davidson Sportster?
When current is sent to the ignition coil from the ignition module or E.C.M., the primary winding energizes and creates a strong magnetic field. The secondary winding increases the voltage as the magnetic field is created and sends a high energy spark to the spark plug.

Why is my spark plug not working on my Harley Davidson?
A spark tester. Spark plugs may not create a spark when the ceramic case is cracked, the electrode tip is broken, or the electrode is worn. If the engine has been running poorly for some time, the plugs may be covered in soot or fuel.

Where is the starter on a Harley Davidson 883 Sportster?
Connect your red probe to the solenoid positive wire. This is a fat 12 or 14 gauge wire on the cylindrical portion of the starter. Connect the black probe to a known good ground. 12v should be present in this wire at all times. Figure 3. The starter location on a 883 Sportster.
