Hi and welcome to FixYa,

Initially, determine if there is a clicking sound when the START button is pressed. The click is significant. If there is, this indicates that the starting relay is engaging but for some reason, the starter motor is not cranking. This could either indicate a faulty starter relay (particularly the contacts) or a faulty starter motor (specifically, the carbon brushes). To determine which:

  • with the side covers off, expose the starter relay particularly the 2 large terminals;
  • have somebody start the bike normally using the key and button start switch;
  • determine if indeed the clicking is coming from the starter relay;
  • while the start button is still pressed, jump the 2 big terminals;
  • if the engine cranks, then the internal contacts of the starter relay are corroded or burned;
  • if the engine will not crank, then the starter motor is faulty.
Good luck and thank you for using FixYa.

2004 cut out..then started..then cut off while turning into drive..steering locked..tried to start..whirring sound but won't start..running fine before


> whirring sound

Not related to other described problems but this is the sound when a starter is not engaging the teeth on a flywheel.
This implies either a failed Bendix that shoves the starter gear into the flywheel or a missing tooth or teeth on the flywheel.

Starter works fine but won't crank engine. the pick up has to be given a push first before it starts


If the starter is spinning when you try to start but doesn't spin the engine over then you most likely have teeth missing off the flywheel ring gear. The facts that you say you have to push it and then it starts means the flywheel position changes and the starter has good teeth on the flywheel to engage. To confirm this next time the engine won't crank over remove the starter and look inside at the flywheel for missing flywheel teeth.

2002 GMC 2500 HD Duramax starter will skip off ring gear every once in a while but not all the time. I've replaced the starter once. replaced starter relay once. And had the chargeing system and battery...


Check flywheel teeth. Might be missing some teeth on the flywheel. Remove starter and you should be able to see flywheel. Turn flywheel and check all teeth.

Grinding when starting, replaced starter one month ago engages well sometimes, but now will not engage flywheel could the flywheel teeth be worn or broken?


The flywheel is worn in that specific area. Engines tend to stop in the same one or two positions, and it is those teeth that get cachunked every time you turn the key. This is ok if the bendix does a good job of threading the gear into the flywheel teeth, but the problem is that now that the teeth are half worn away, the starter attempts to mount its gear to the teeth, but before the gear is fully seated, the contacts in the motor make, the motor starts to turn, and the not-yet-seated gear bounces off of the flywheel teeth. This is what causes the teeth-grinding sound (your teeth grinding in your mouth too!) when you turn the key. . There are two solutions: The first is to, of course, replace the ring gear. . The second is hard to explain, but a good starter rebuild center (if there is such an accessible animal around anymore) will know what I'm talking about: The starter gear must have the lagging edge of each tooth ground so that each tooth will look like a chisel. The "pushing" side of each tooth must be straight and come to the point (and not be beveled). The "non-pushing" lagging side of each starter tooth should have the bevel ground in on that side. This grinding is done easily by a small angle grinder or a Dremel Tool with a cutoff wheel. . This does one thing: It assures that the gear will "spin in" without bouncing. If ground correctly (it's not hard to do), you will get successful starts every time. This is a common fix for Toyota 4-cyl with this horrible all-too-common problem. Good luck.
