Harley Davidson - FXSTI Softail standard cranks but will not start

Hi Anonymous, This one is a tuffy since I don't know what year your bike is. If you have an early model you could have a bad run/stop switch, ignition sensor, ignition switch, ignition module. If you have a late model could be crank positon sensor,electronic control module, but on the late stuff you can pull up trouble codes on the odometer and that would at least point you in the right direction. Good luck

2008 electra glide battery draw, test light pulses, now bike wont crank over

The pulsing could be the alarm module. When bike is turned of, you will get small draw for a minute or so and then it should go very low, below a miliamp or so. This is the alarm module setting itself. Check for this. Is battery gone flat while checks were being made? Make sure ignition switch is on when disconnecting battery if alarm (Stock HD) is fitted. If not, alarm module gets confused and can cause problems. The corrct procedure for disconnecting a battery from an alarm fitted HS is - alarm off, ignition switch on, pull main fuse (Maxi Fuse), disconnect battery. To fit, ignition stitch off, connect battery then install main fuse.

01 600 f4i crank sensor what is it for, not getting any fire does it help the bike crank

The crank sensor indicates that the crank is actually spinning, and NO it doesn't "help" the bike crank, but should not stop the "Fire" However IF you exhaust every other possibility, then replace it and see? However really first, what you need to check the battery earths, coil, or electronic ignition, points, or reluctor, all wiring to and from battery and ignition, check all leads, usually it's best to simply replace the spark plug and leads to be sure. Electrical problems can be hard to sort out. Just slowly work through all possibilities, try to get a service manual, this will help you greatly, Google for one or try the bike shop/manufacturer.

98 sportster crank no start has no spark found no power feed to coil appreciate any help you can give

Check ignition fuses and circuit breakers. Check power at battery and follow the electrical leads from battery to ignition and to coil. Has anything been added or removed from bike before you noticed this problem? Do you have a security system?

~ 1991 STX38: Starter engages, engine cranks but won't start, when key is turned off, engine continues to crank. Disconnected battery to stop engine from cranking. Upon attempting to reconnnect battery...

The starter solenoid may be stuck in the on-position. To check this, on the starter, remove the small wire connected to the solenoid coil terminal. If the starter still runs, the solenoid is stuck on. If rapping it with a hammer doesn't stop it, the contactor pin is welded to the motor contacts.

No spark

Hi and welcome to FixYa,

To my understanding, the problem is 'no spark' yet the engine cranks. Generally, to consider are:
  • pulser coil (least likely);
  • ignition coil (likely);
  • interlocks (likely);
  • CDI (most likely).

Offhand, the CDI would be the main suspect. Since the CDI is sealed, it is not possible to do component level checks. The only way to check if the CDI is good is to check the external connections; if they are good and yet no spark, then the CDI is bad.

How to check the above:
  • to check the pulser coil, measure the low voltage coming from it using an analog/needle type AC voltmeter. While cranking, it should show a flickering low voltage;
  • to check the ignition coil, use a continuity tester. Primary should measure 3 ~ 5 ohms while primary to the high voltage end would measure 15 ~ 18 kilo ohms;
  • the ignition coil has 1 terminal connected to the IGN +12 while the other terminal is connected to the CDI. This should have a pulsating voltage when cranking.
  • all the interlocks could be checked with a continuity tester. Please note that most interlocks has a diode connected in series with their wires.
The interlocks include:
  • clutch switch;
  • side stand switch;
  • neutral light switch.

Good luck and thank you for using FixYa.

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. ,,,
