The bendix on the starter could be bad, but since it's a chevy the part is easy and cheap to replace. You should be able to get these for around $10 from any auto parts store. In order to replace it you'll have to remove the starter from the truck.

It'll take a half hour tops to remove the starter, and you'll need a set of metric sockets. Disconnect the negative battery cable before you do anything. Since the truck sits kinda low you may want to raise the front end with a jack or ramps. Locate the starter and disconnect the two bolts holding it to the bell housing. Rotate the starter 180 degrees before trying to get it off, it's a pain to get off if you don't. Once you get it out, let it dangle by the cable between the frame members. Take off the small wire first, otherwise you risk pulling out the eye connector from the little wire. Then take off the big cable and you should have it off the truck.

To put it back on, just reverse the instructions. Connect the big cable first and rotate the starter before putting it back on

Remove the starter and either replace it or check that the solenoid is pulling the bendix drive into position and that the sprague on the drive only permits the drive gear to turn one way freely (may turn a bit the other way but should offer resistance.) Also look at the flywheel teeth to make sure they are still intact.

Remove the starter motor and make sure the ring gear is intact.if it appears ok then check the starter motor as the arm that pulls the pinion out could be broke

Why does my starter engage for only a second, then spin freely after that. it was removed and tested at Autozone and passed. The starter stayed engaged during the test when no load was encountered.


Hi Anonymous

What I believe you've said is that you turn the key to start, the engine turns over for a second, then you just hear the starter spinning but no engine turn over. Yes?

Then you took it to Autozone and tested it and it stayed engaged during the test. The differences, possible or real here, are the load on the starter gear end, and the electricity driving it.

There are a couple things happening in the start cycle. The motor starts spinning and the solenoid pushes the spinning gear forward to engage the toothed edge of the flywheel. If the solenoid doesn't push enough, the gear won't engage. So, one thought is that there's an issue with the solenoid - it may push the gear out just fine, but lack power to keep it pressed forward if there is back-force from the engine.

If you have a poor connection to the battery, the solenoid may not draw the current to keep the gear engaged. Checking the hot (red) wire both at the battery and where it attaches to the starter is the primary diagnostic there. Even if the battery has a good charge, the current draw if starting is the heaviest load it encounters in a typical day of driving, so the ability of the battery to dump that charge quickly in a pulse of high current is also important, and non-corroded, tightly connected wires help.

The starter gear also has a clutch in it - akin to the freewheel on the rear of a bike, or a ratchet. This lets the gear spin faster than the starter motor once the engine catches, so that the engine doesn't essentially grab the engaged starter motor and spin it waaay too fast. letting back on the key lets the fast spinning gear disengage without trouble. If there is an issue with that clutch/ratchet, that might also be allowing the gear to spin without it actually pushing - like the clicker in a ratchet sticking so that it'll spin either way.

After that.... there is likely both a relay and a fuse for the starter. Not a bad idea to check that neither is blown, or, in the case of the relay, looking sort of browned and cooked.

Hope this helps!

Starter not engaging


The starter solenoid mounted on top of the starter has two functions, as the key is operated the solenoid slides the starter pinion to engage the flywheel, THEN operates heavy duty contacts to power the motor. The solenoid is not engaging the pinion.1726daf9-e191-4168-8e99-cab63cae5995.gif

have a compression check done on the engine If the motor spins faster then that indicates a compression problem form no resistance in the motor.

Starter relay ground


Usually if the starter spins but does not engage the flywheel, the problem is the flywheel or the bendix drive in the starter. The starter gear is supposed to extend to meet the flywheel when the starter spins.

92 honda civic hatchback new starter spins does not engage flywheel, could it be a fuse


unlikely as the motor spins. It appears that the motore solenoid is allowing the motor to spin before engaging the teeth in the ring gear. ON a lot of starters the pivot pin is adjustable to allow for correct engagement.Remove the starter and check that the solenoid is fact connected to the clutch part of the starter. Check that you have the correct starter for the engine

Starter motor whines but wont engage with engine on my rover P2


You will need a new starter rebuilt ect. to replace the one you currently have that is defective. you sound like you are spinning the starter motor but the starter bendix is no longer engaging the flexplate/flywheel on the engine.

Battery is good but when I turn it on it just clicks won't start,maybe after 20 times it starts


Without hearing the sound it makes - it's kind of hard to diagnose.

The engine starting process consists of turning the key to start, the starter motor's rotor moving forward to engage the engine's flywheel, and then the starter motor 's "rotor" spinning until you move the key from "start" to "run". You can hear the starter motor spinning - but one usually can't hear the rotor moving forward to engage the flywheel. As a result, you hear the odd spinning sound - which is the starter rotor spinning. The engine never actually turns over because the rotor never engages the fly wheel. If this is the case, then it is very likely that your starter needs to be checked and / or replaced.

Good luck!

I have a dodge neon 2004 sxt the started sounds like it is turningbut the motor does not turn at all


Hello, sounds like the gear in your starter motor is not engaging/thrusting forward. It will still spin but it will sound like a effortless free spin, have your starter motor looked at. The other problem it could have but it is a very slim chance is that the flywheel which the starter motor engages onto is stripped, this use to happen in the older cars but its not a common problem now.

Starter motor spins but the solonoid does not engage, after the car just shut down on the highway


Starter motor spins, but does not engage
  1. Check the starter motor for a seized or binding pinion gear.
  2. Remove the flywheel inspection plate and check for a damaged ring gear.
