The "Bendix" is the starter drive in the actual starter. When you crank the starter the bendix is driven forward into the flywheel. It sounds like the bendix spring is worn or week and it's not meshing with the flywheel. Instead it's grinding against it. If you're ambitious you can pull the starter, dismantle it and replace the bendix or option 2 replace entire starter w/new or rebuilt. Both will have new drive and save you a bunch of time.

I have just overhaul my engine but when the ignition on it cranks but cant start

Which car is this? Anyway if its cranking then your starter motor and related wiring is fine. Open the engine oil filler cap or head cover and then try to crank and see if tappets are actually moving or not. You should also pop out the fuel line from carb / mpfi to see if actually fuel is coming out of line or not. Because sometimes fuel pump produce humm sound but do not actually pump fuel.

My car doesnt want to start up right away in the morning. Almost like its really cold out and it takes it a min. The rest of the day its fine runs great. Any ideas?

Reason 1 - Gasoline, like any other liquid, evaporates less when it is cold.You have seen this -- if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk. When it gets really cold, gasoline evaporates slowly so it is harder to burn it (the gasoline must be vaporized to burn). Sometimes you will see people spray ether into their engines in cold weather to help them start -- ether evaporates better than gasoline in cold weather.

Reason 2 - Oil gets a lot thicker in cold weather. You probably know that cold pancake syrup or honey from the refrigator is a lot thicker than hot syrup or honey. Oil does the same thing. So when you try to start a cold engine, the engine has to push around the cold, gooey oil and that makes it harder for the engine to spin. In really cold places people must use synthetic motor oils because these oils stay liquid in cold temperatures.

Re ason 3 - Batteries have problems in cold weather, too. A battery is a can full of chemicals that produce electrons The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.

All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use "block heaters" to get around these problems. A block heater is a little electric heater that you plug into the wall to keep the engine warm.

I have 01 kia rio and the only way my car will start is if it is jumpped but other than that it acts like it wants t turn over but it never does.. I thought it was my altenator but someone told me if i...

If the car can be jump started and then runs fine once it is started then the problem is your battery. Once the alternator is being driven by the engine, that is producing the power needed to run the car and then you have no problems from what you have described.

You will find that the battery is virtually dead or faulty and needs to be replaced. It clearly does not have sufficient power to turn the starter motor and crank the engine over.

If the problem was not with the battery then you would not be able to start the car by hooking up power from another vehicle.

The battery is the only power source in your car to turn the electric starter motor to start the engine.

Make sure you clean up the ends of the cables before you install a new battery to ensure good contact with the battery terminals. Do not install a cheap battery because it will probably not last more than a couple of years. A very good battery when properly maintained will last 3-4 years - sometimes more.

I would still have the alternator checked to ensure it is producing sufficient power. If it is not, power will be drawn from the battery when the car is running and the battery will discharge. I do not think there is a problem with the alternator from what you have said.

I had a problem like yours on my 96 towncar and after literally months of replacing the wrong parts.
I bought a crank shaft sensor and crawled under the car to try and install it. Looking at how oily it appeared I unplugged the wires from it and cleaned both the wire plug and the sensor with some electrical contact cleaner available at most auto parts stores , and that was over a year ago and the problem has not returned since then. The sensor is located on the passenger side just behind the harmonic balancer under the front end of the motor. If yours is oily it would be worth a try.
Hope this helps.

The problem sounds very much as if it is on the electrical side. OK so here is the path: Battery, Ignition switch position 2 and fuel pump is engaged, position 3 and current passes through the starter fuse and relay to the starter solenoid (located piggy back on the starter motor) The starter solenoid pushes the starter motor armature forward to engage with the toothed rim of the flywheel. At the same time the armature bridges the contacts between the high power contacts to cause the motor to spin up and turn the engine over. Check the external stuff first. Make sure the battery terminal and cable connections are clean and tight. Make sure the earth return strap from the engine block to the car body is intact, clean and secure, free of corrosion (unbolt, wire brush clean and re-bolt). Remove starter motor and solenoid, dismantle and check on the heavy duty electrical power striker plate contacts for wear, replace as necessary (often these starter motors are by Denso and replacement kits for the copper contacts can be got for less than $10). Check the main starter fuse, clean the contacts until bright. Check the starter relay. If possible remove the cover and inspect the printed circuit board, resolder any dry or annular cracked joints. Pass a folded piece of fine sand paper between the electrical breaker contacts to freshen them up. Make sure the relay pins and corresponding sockets are all clean and bright. The above sounds like a lot of work but once it is done and you are reassured that everything is as it should be you will not need to re-examine this for another ten years or more. Lastly, make sure the ignition switch is OK. Contacts can become worn and if you find that a wiggle the ignition barrel with the key in results in 'start' versus 'no start' then the fault is here.

My 95 Dodge Dakota won't start. The electrical seems to be working fine but the engine won't even try to turn over

sounds like you may have a defective starter solenoid, the contacts in the solenoid get burnt and u get a no crank.

1995 Subaru Legacy electrical nightmanre...PLEASE HELP!!!!!!

Really sounds like you need to make sure all the ground wires body and motor are good. Sometimes a poor ground will do that. The electricity will try to find any thing that it can to return the circuit. I even had one time the ground was going through the shift cable. Which destroyed the cable after a while. Good luck and hope this helps.

Renault megane scenic RX4 climate control fan has failed

the vehicle is old enough that the fan blower motor sounds like it is in need of replacing. when you hit the dash it causes the brushes in the motor to contact enough to start the electrical connection, it may stop when it gets hot, or is turned off. the ticking sound is more than likely the bearings wore in the motor enough to cause the cage fan to touch the housing enough to cause the sound.
