The car (+200 000 miles) is having starting problems. The car starts with no problems in the morning but then if you turn it off after driving for while it wont start and wont crank. You can hear a humming sound on the right side of the engine.It has done this a couple of times.
Thinking it might be the starter motor. Would really appreciate it if you can provide me with some solutions.
If the humming noise is more like a whirring sound, you have a bad starter-motor solonoid or "bendix."
First - open the hood and have one of you listen while the other tries the starter. If the starter motor makes a whirring sound but nothing else happens, it is certainly the "bendix."
The same switch that turns the motor on, also engages an electro-magnet (the bendix) that throws the starter motor gear out and engages the teeth in the motors flywheel thus allowing the electric starter motor to turn the engine over. When the engine starts, it spins the starter motor fast enough that it mechanically throws the starter gear back into the starter even before you release the starter and disengage the magnet.
OK - now that you know what it is, what do you do about it.
While the bendix can sometimes be cleaned and work a while longer, sometimes a really long time longer, it is seldom worth the effort to remove the starter mechanism, take it apart, clean and lubricate (with the proper lubricants) and re-install just to see if that will work.
Usually, the best solution is a new or rebuilt starter. You can get one on Amazon, Autozone, NAPA, etc. and the price will likely vary a lot. You can get one from the dealer as well but it may cost more than the car (some exaggeration). Check prices - they vary a lot, sometimes by as much as 2-3x. I think the original starter motor on your car is a Denso, but there are lots of good aftermarket starters available.
Starters are pretty easy to change. I suggest looking on youtube. Just make absolutely sure you disconnect your battery before starting this.
Changing the starter motor (the bendix is attached and comes with a rebuilt one) takes about 30 minutes or so on that car.
Basically, you disconnect the wires, unbolt the old one, slide it out, slide in the new one, bolt in in, and reconnect the wires. - then reconnect the battery and start the car.
Good luck.
Testimonial: "Thank you so much...I really appreciate,the problem was definitely the starter"
If you just hear a click, try this:
This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
I would check battery cables & connections. Many times connections get aggravated if they're corroded or slightly loose and cause a starting issue. Also check the wires at the starter.
Hope this helps

if this problem persists then you could check a few things on it, like on the times when its not even making a noise when trying to turn the key, use rubber/wooden object and tap the starter motor but not touching the contacts on the back. if this amkes it spring into life then it will be your starter motor if this does nothing then it will be a dodgy battery supply. does it also make like a screaching noise while trying to start? if so then definitely your starter motor

There could be a few things causing this. When the car finally starts, is there any smoke coming out the exhaust pipe? White smoke would mean your headgasket is leaking and is letting coolant into the engine, then it is burned along with the fuel. Does the car run hot? Meaning has it ever overheated? Back to the smoke, if its black, your oil is getting in and is burning.
Now, the reason why it would be hard for a car to start, could be, a leaking headgasket, flooding the car while the car is sitting.
And yes, the car would be able to crank, but just wont start, for a while...because it has to get rid of all that fluid that has leaked into the engine while sitting at night.
Another thing you could look at, is your fuel pump, is it supplying a sufficient amount of pressure? If it isnt, it will take a while for it to pressurize and deliver fuel into the engine. You can check the fuel pump yourself by renting a fuel pump pressure tool from stores like autozone, kragen and more.
Your gas cap on tightly?
Good luck with your problem.
SOURCE: Problems Starting my 2009 Honda CRV
Your post interested me, as I just purchased the same vehicle lasts month. The grinding noise while attempting to start the CRV sounds like like a problem with the starter 'clashing ' with the flywheel. When you turn the key to start there is , a small gear in the starter on a shaft that advances (moves down the shaft) and meshes with the flywheel (which is a large 'gear'). When they mesh together, the starter gear will spin, and turn the flywheel, which 'cranks' the engine over to start. When a car is old, you can experience a loud grinding noise, as the wear and tear can cause the gears to clash, not mesh smoothly. Since this is an '09, that of course isn't a wear and tear issue, something was not tightened during assembly, or is defective. You MUST bring it to the dealer, to establish that there is a problem, even if they deny it. To continue to drive it could cause damage to components (actually driving it is probably ok, it's the starting it that will cause damage). So, insist that they check it out, you may be surprised by their desire to fix it, and have a happy customer to advertise their cooperation and quick fix of the problem. Hondas are great cars, hopefully this is a rare minor assembly or defective part glitch that will be quickly fixed. Keep me posted as to your visit to the dealer. Remember that you can bring it to any Honda dealer, although I would start with the one where I purchased it. The car is under warranty, get them to fix it, and enjoy your new car.

The source of the problem seem to me it is an electrical problem,in this case you have to diagnose the ecu.
