It sound to me like the starter solenoid is bad. If you can remove the starter yourself you should be able to repair the problem. You will need to remove the terminal cover from the solenoid(be careful because there are wires connected to the underside of those terminals so do not force it.) If you look at the back of the terminals you will probably see that the inside part of the bolt is burned. loosen the nuts that hold the terminals and rotate them so that the burned sections are to the outside then tighten the nuts back. (not too tight because you can break the plastic) You can test the starter before you put it back in the van (after reassembling the starter itself of course) by connecting a set of jumper cables from the battery to the starter. Negative gets clipped to any good metal tab (usually where the mounting bolts go is a good spot) and the Positive cable goes to the big terminal where you first removed the cable from. touch a screwdriver to the smaller terminal and then touch the screw driver shaft to the + CABLE CLIP (not the terminal because you can damage the threads if it arcs) Be sure to have a good grip on the starter because if it works then it will jump. And keep your fingers out of the hole where the gear (Bendix) is because when you bridge the contacts the Bendix will pop forward and will shred your fingertips.

do not think alarm would cause this do you have a check engine light on?? there is a coolant temp sensor that reports to pcm it could be out of range you need to hook vehicle to a scanner and check the temp that is being reported by coolant sensor when cold and when hot also may want to look at mass air flow sensor also have you even thought of ignition module what symptoms you have sounds just like an ignition module problem

It is possibly that the bedix in the starter is not able to push the gear out to make contact with the flywheel. The first step is to remove the starter and visually inspect the teeth of the flywheel. If they are worn in that spot that the flywheel will need to be replaced. If the teeth look good a new starter should take care of the problem.

Most of the time its the starter and the flywheel is fine. However repeatedly try to start the vehicle when it makes the grinding noise can ruin the flywheel.

I have a 1991 f150 5.0 starts right up and runs great after drive for a while and shut it off has to cool off before starting or acts like starter dragging I have changed starter 3 times and timing is


Really need to know how many miles are on it and is it an all original Engine...?...Other than that I understand your problem...It surely sounds like you need a heat shield and shim the starter..I know it has happened to a few mustangs and camaros...That is how I repaired them...Be sure and make sure battery has full power....Shimming will line it up more with flywheel. Everytime the starter engages the gear slides out from the starter and connects the flywheel in order to turn the engine over..,then after it turns the flywheel and starts Is when you release the key and the starter gear slides back into starter..If it gets too hot the starter gear will be weak and not slide as easily....So replace or get a heat shield...Since you will be removing starter to install a good heat shield measure the length of the starter nose and the distance from starter gear to flywheel and shim as needed...Remember you have to allow for the starter gear movement ..

I have a 89 jeep wrangler 4.2 with peugeot transmission ...I just bought jeep it started but makes a grinding sound like the starter bad then all sudden it won't crank...so I got new starter replaced...


recheck the parts to be the correct ones because what you are describing is a gear mesh problem. ensure the gear on the starter matches those gear teeth on the flywheel. once you know they are matching and are correct for that year and size of engine, you will need a variety of shims to set the distance between the two correctly. (which you already have experience at). But it is important you have the correct starter because the solenoid and the throw-out spring are specific made to travel a set distance. If that distance is not far/long enough the gear will not full engage the width/thickness of the flywheel tooth/teeth (which causes the starter gear to strip those teeth of the back side of flywheel). SO you need to do some serious looking at those parts and the meshing when solenoid is engaging.

Sounds like the the Bendix is bad in the starter, which pushes out the drive gear to engage the flywheel. You'll need to replace the Bendix or the starter. It's a bit tough to get to the starter, it is underneath the intake manifold.

You need to make sure the starter is not staying engaged,if the starter is still turning,while the engine is running can damage the flywheel teeth.Look for a starter solenoid to be the problem,on the fender well.If the starter is not staying engaged,then the flywheel teeth are damaged on the flywheel.

2000 kia sephia problem


It could be a lot of things but I would be very suspicious of the starter and flywheel. The fact that it will start with a push suggests that your codes are not the problem with starting. Your starter's bendix drive could be weak which means it will disengage before the car starts. The solenoid could be getting worn and not putting enough juice to keep the starter running. The flywheel could have a "flat" spot.
To check the flywheel for a "flat" spot you will have to look at it and turn it by hand. The best way is to use a screwdriver or small pry bar and work it around that way. You are looking for missing teeth, teeth that are ground off or narrower than the rest. If you find that the flywheel needs to be replaced. I would try to start the car and when the starter kicks out, start looking right there.
The only way I know of testing the starter and solenoid is to replace them and see if that works. Hope this helps.

Grinding starter on my 1988 Ford Bronco II


the sound you hear is the starter grinding against broken teeth on the flywheel, for that to be repaired the flywheel on the vehicle will need to be replaced.

My starter teeth all broke off any reasons


Drive may have been engaged when engine running, like as in accidentally forgetting it was already running, or drive was sticky & stayed engaged after start up. If this is first time it's happened, I wouldn't panic, but observe flywheel/ring gear teeth when you change starter. Check for good alignment when installing new one, just to be sure. Any odd noises from starter prior to this happening?
