As an electrician I can give you a vague answer with the information given. You need more specifics to do the calculations for the load amps and the supply voltage.
The particular motor I looked at is a .6hp fan motor -4.0 Amps @ 230V
(2650 x Full load amps ) divided by supply Voltage = MFD
Example 2650 x 4amps = 10600 divided by 230volts = 46 MFD
But this is a general statement. The proper cap should be determined by researching the particular model you have.
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
Connect your start capacitor in series with the start winding.Connect the run capacitor in the common terminal and Line 1 of the power supply.
There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.

No.
if it is a capacitor start and run motor, this is because of shorted capacitor

No. You won't be able to start the motor without the capacitor.
It sounds like the starting capacitor is about to give up.
A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.

capacitor start motor
A capacitor start motor is a split phase motor that uses a capacitor in series with the start winding to cause a greater phase shift, resulting in greater starting torque. It uses a centrifugal switch to switch out the start winding and capacitor once the motor is up to speed. I assume this switch is what you're referring to as a "relay".
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
