If you put the spark plug in the end of the ignition wire while its out of the cylinder head and ground the point on the plug and then either kick it or if you have electric start turn it over you would see a spark. The plug has to be grounded

02 Harley fatboy diving down the road just shut off tried to restart will crank over but won't start no spark to plugs changed crank shaft sensor still no spark changed coil still no spark any ideas


Hi, Stephen and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Discharged battery, 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.
8. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, cable connections loose, or connected to the wrong cylinders.
10. Ignition timing incorrect due to a faulty ignition coil, ignition module or sensors (MAP, CMP, CKP, O2 and/or BAS).
11. Security alarm needs a reset.

Hear pump kick on an it starts up an shuts off after a few seconds


Fuel system may have a problem at fuel filter, or pump is shutting down. Make sure you have spark after engine stalls( DO NOT TURN KEY OFF ). If you do turn key off restart let stall happen do not turn key this time. Pull a spark plug wire at spark plug. Put a spark plug into that end of the spark plug wire. Ground the base of the spark plug on a good none painted placed so that you can see the spark, then you turn the key to crank watching for sparks at the very end cap of the spark plug. My son has a 2013 Harley, I think this fill fix your problem, Lee.

Wont start got spark fuel pump works new crank shaft position sensor


Hi Joseph, when checking for spark on twin cams 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.
5. Fuel valve or filter clogged.
6. Vacuum hose to automatic fuel supply valve disconnected, leaking, or pinched.
7. Discharged battery, loose or broken battery connections.
8. Loose wire connection at coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module, or sensors " Manifold Absolute Pressure" "Camshaft Position Sensor" "Crank Position Sensor" "Brake Apply Sensor
11. Engine lubricant to heavy ( winter operation )
12. Sticking or damaged valves or push rod wrong length.
13. Primary cam sproket spline sheared or missing spacer.
14. Security alarm system not disarming.

2003 harley no spark juice goin into coil none cumin ouy changed computer coil and crank sensor stil no spark


Test the primary coil resistance on your coil. Disconnect all the wires going to the small terminals on your coil. Using a good ohm meter, test the resistance between the two small terminals. You should read somewhere between 2 and 3 ohms. If you read more, the coil is bad.

You can also test the coil by leaving the "hot" wire on the coil and replace the other side with a short piece wire. Turn the ignition on and temporarily ground the short piece of wire you put on the "out" side. When you take the wire away from ground, you should see a spark at the plugs.

Good Luck

My 92 nighthawk 750 is leaking oil on the left side. with my foot on the peg and my toe on the shifter it drips on the toe of my boot. What is that cover called? It is about 6 inches in diameter.


Left crankcase cover or pulse alternator cover. Is the cover over the left side of the crank shaft end. There is also a "left cover" that covers the counter shaft sprocket. I believe the cover you are looking for is shown on the pulse alternator page of the micro fiche.

How too replace connecting rod on a ttr 125l. I have a 2001 ttr 125 with a seized conn big bearing. and I would like to know the proper way of splitting the crank too replace it


The top end comes off then the left and right side covers, flywheel, clutch and shift shaft. Now a case splitter is used to split the center case halves. To replace the bearing you will need a hydraulic press to disassemble and reassemble the crank halves. If the bearing is seized you should replace the bearing, crank pin and the connecting rod. The crank must be realigned using twin dial gages. Personally, I suggest a new crank assembly be purchased from www.babbittsonline.com ( $241 ). I would replace the crank end bearings at the same time and also the sprocket shaft outer bearing and seal. Please rate my answer.

SPARK


Connect your tester to the big thick spark plug lead and crank the engine. You should see a nice big fat blue spark. If you don't disconnect the engine kill button. If there still is no spark you will need to determine if the engine has points or electronic ignition. Most (but not all !) bikes built before 1980 have points ignition. Most bikes built after 1980 (but not all !) have some sort of electronic ignition system. If in doubt pull one of the crank end covers (Usually 2-3 screws) and look ! If you have a battery and coil points system see the points page If you have a points magneto system see the Magneto page. If you have an electronic ignition system see the electronic ignition page. ,,,
