White smoke from the exhaust is a symptom of coolant entering the combustion chamber. You either have a blown head gasket or cracked head or both. STOP driving the car until you can have it repaired.
The motor is bad
tell me
Follow the exhaust off the back of the motor and on the exhaust pipe it is the first sensor you come too.
The armature bushings inside the starter motor are probably shot. Time to replace the starter.
most likely a failing starter
When cranking, the ballast resistor is bypassed to give a hotter spark. If during cranking you do not have power at the coil, but when the key is turned to run you do; there is a problem with the bypass circuit (sometimes it comes from the starter motor solenoid wire)
Voltage flow into a starter motor, never out of it. Use the voltmeter to measure the voltage at the starter motor before starting to crank and then whilst it is cranking. (Before cranking, the voltage appears across the starter motor relay only.)
On the exhaust manifold, near the headpipe connection.
Induction motor
its the motor
Good battery,slow cranking speed ,noisy,
Cranking battery.
