Question about 2002 Harley Davidson XL 1200 C Sportster Custom

1 Answer

The engines turns vigorously when I press the Start button, but won't run. There is plenty of fuel, the spark plugs were renewed about 3,500 miles ago [when it was serviced by a n HD dealer]. I have cycled the key from 'off' to 'ign' and back again - in accordance with the Owners Manual. On turning the key to 'ign', the following sequence occurs : Neutral light comes on and stays on until a gear is selected. Oil pressure light comes on and stays on until there's sufficient oil pressure, then it goes out. 'Red Key' light [immobiliser ?] comes on, then goes out after a second ot two. 'Engine' symbol comes on with Red Key, then goes out for a second or two, then comes on again. System Relay 'clicks' once, then clicks again after a second or two. On pressing the Start button, the engines turns normally, but does not start [engine symbol remains on]. All fuses have been checked for both corrosion and integrity - no problems found. Both System and Starter relays have been visually checked for corrosion on the connector pins - no problems. There is approx' 70 Ohms across the Starter solenoid terminals, and 'infinity' across the relay connecter terminals in it's default state. Unfortunately I have no separate 12v source to bench test the Starter Relay. Any clues ?? :-(

If the starter turns the engine over, there's nothing wrong with the starter relay, the solenoid, or the starter. The reason your engine won't run is it has no spark for some reason. I'm afraid that this is all I can tell you. For some reason, the system is not firing the spark plugs. Check the fuse. I hope this helps but I must confess that I don't know a lot about Harley's new electronic system after 2000. I work on the older bike that don't have this system.

Good Luck

    Thanks wd4ity. It turned out to be the System Relay; the second 'click' was the clue.

    A "system relay"? I've never heard of such a relay but then, like my profile says, I don't work on the bikes made after 1999. They've got all these computers (ECM) and stuff on them. I'm not afraid of that stuff or wiring having completely rewired many bikes in my life but I just don't know anything about the computer stuff. I guess I could learn but I've got plenty to keep me busy as the dealers won't work on anything built before 1986. Maybe I'll ride over to a friend of mine's house and ask where I can get the information and study up on it. Then I'll need to purchase the special tools I need to work inside the cam chest of a Twin Cam. Thanks Ian. Ride Safe now.

02 hyundai accent engine quit running won t start codes come up po300 po301 po302 not familiar with 4 cylnders when turning over sounds like no compression

codes p 0300 is random misfires and codes p0301,2,3,4,5,6,7,8 are the cylinders that are misfiring
so un you statement the problem cylinders are 1 and 2
misfires are normally problem injectors and low fuel pressures so have the fuel pressure checked to make sure that the pump is running correctly, the pressure regulator is operating correctly ans the EVAP system is venting the tank correctly
use a couple of injector cleaner in the tank to clean the injectors

Hi, Powersthepot and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the choke.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. Fuel injectors stuck open.
13. Quick disconnect check ball stuck.
14. Compression below 75 PSI.
15. A stuck-bent-burnt valve.
16. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
17. 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.
18. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
19. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections are loose or connected to the wrong cylinders.
20. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
21. Faulty neutral, clutch, kickstand safety switch.
22. Faulty fuel pump or fuse or relay.
23. Faulty or corroded run/stop switch.
24. Tilt sensor needs a reset.
25. Security system not disarming alarm needs a reset.
26. Check for engine trouble codes.

Was driving 65 miles an hour small back fire and engine stop running will turn over but won't start.

check for spark at the spark plugs. If ok then check for fuel and if that's ok then you need to check the timing chain.

Was riding bike and was stopped at a red light when it made a loud noise and died, now it won't start. The engine cranks and turns over but won't start.

You didn't say what year and model the bike was but on any four stroke engine, you must have three things for the engine to run. You need fuel, spark, and compression. The easy one to check is the fuel. Take your air filter off and make sure you're getting fuel to the engine. Then, check your spark. Pull the spark plug wires off the spark plugs in the head and insert another set of plugs in the wires. Ground the plugs against the engine, turn the ignition switch on and press the start button. Watch the plugs to see if you have spark. The next test is compression. With the engine cold, remove the spark plugs. If you have a compression gauge, connect it to one of the heads and spin the engine over with the starter. If you don't have a gauge, simply put your finger over the spark plug hole. Turn the throttle wide open and press the start button. You should show about a hundred pounds of compression if you have a gauge or the compression should blow your finger off the hole with a good deal of force if you're checking it that way. If you have all three of these and they're timed correctly, the engine should run. If the engine won't run, find out which of the three elements is missing and work from there.

Good Luck

Harley has compression but won start

For any engine to run, you must have three things. Compression, spark, and fuel. If you have compression, it must be something else. On your '93 FXR, take the plugs out of the heads, put them back into the spark plug wires and ground them well to the engine. Turn the switch on and press the starter button. Watch for the spark plugs to spark. If you don't have spark, you have an ignition problem. Check your ignition coil, your "Run/Stop" button, and power to the coil.

If you do have spark, then the problem is probably a fuel problem. Take your air cleaner cover and the filter element out of your air cleaner assembly. Make sure your fuel petcock is in the "ON" position. With the engine "OFF", crank your throttle grip wide open. As you twist the throttle to wide open, you should see a stream of gasoline shooting into the throat of your carb. If not, your problem is a fuel related problem.

Good Luck
