An automobile starter motor (larger cylinder). The smaller object on top is a starter solenoid which controls power to the starter motor and engages the Bendix drive.. A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine's operation under its own power.
An engine in this condition will not start until the excessively rich mixture has been cleared. [2] It is also possible for an engine to stall from a running state due to this condition. Engine flooding was a common problem with carbureted cars, but newer fuel-injected ones are immune to the problem when operating within normal tolerances.
A cold start is an attempt to start a vehicle's engine when ambient temperatures are much lower than its normal operating temperature. [1] A cold start can be difficult for an engine due to higher viscosity of oil and fuel in cold temperatures.
A bad crank position sensor can worsen the way the engine idles, or the acceleration behaviour. If the engine is revved up with a bad or faulty sensor, it may cause misfiring, motor vibration or backfires. Acceleration might be hesitant, and abnormal shaking during engine idle might occur. In the worst case, the car may not start.
The high-output cam profile is not activated until approximately 6,200 rpm, (lift set-points are between 6,000–6,700 rpm depending on the vehicle) and will not engage until the engine has reached at least 60 °C (140 °F). The Toyota PCM electronically limits RPM to about 8,200 RPM via fuel and/or spark cut.

Pressure in cylinder pattern in dependence on ignition timing: (a) - misfire, (b) too soon, (c) optimal, (d) too late. In a spark ignition internal combustion engine, ignition timing is the timing, relative to the current piston position and crankshaft angle, of the release of a spark in the combustion chamber near the end of the compression stroke.
