hello?
Expert:  Amedee replied 1 year ago.

I am here.

Have you checked for power down at the starter?

Customer: replied 1 year ago.
i don't know what you mean?
I want to hand crank my engine to see if that is the problem
Customer: replied 1 year ago.
would a starter cause a knocking sound under the hood?
Expert:  Amedee replied 1 year ago.

You could do that.. but your starter motor could be bad preventing the engine from cranking over. You can check this by checking for battery voltage down at the starter while an assistant turns the key to the CRANK position. If there is power at the starter with the key in the CRANK position and the starter is not working, the starter is bad and will need to be replaced.

The starter could make noise if it has low battery voltage. Are you sure the battery is good and fully charged?

Customer: replied 1 year ago.
Sir it is
Expert:  Amedee replied 1 year ago.

Ok, then yes, I would suspect a bad starter motor provided there is nothing wrong with the engine. YES, you could turn the engine over by hand to ensure it is working good.

sir I'm not just done yet
Customer: replied 1 year ago.
where & how could i rotate the engine by hand?
Expert:  Amedee replied 1 year ago.

No problem. I can still help

Expert:  Amedee replied 1 year ago.

You would need to put a socket on the crankshaft bolt and turn it using a breaker bar or big wrachet.

Customer: replied 1 year ago.
where is that located?
Expert:  Amedee replied 1 year ago.

It is on the side of the vehicle but it would be in front of the engine. Keep in mind, the front of the engine is on the side of the vehicle because the engine sits in the vehicle sideways. So pop the hood, look for the serpentine belt and then look for the BIG harmonic balancer or BIG pulley on the bottom. Then find the bolt in the center.
