1. A method comprising:
- measuring, via a sensor onboard a vehicle, sensor values pertaining to operation of an engine of a vehicle propulsion system of the vehicle in response to a start request that has been made by a user of the vehicle, via an engine starting mechanism of the vehicle, to start the engine of the vehicle propulsion system of the vehicle;
determining when a no start event has occurred for the vehicle via a computer processor disposed onboard the vehicle using the sensor values pertaining to the operation of the engine of the propulsion system of the vehicle, wherein a no start event is determined to have occurred when the engine does not start in response to the start request; and
generating, via the computer processor disposed onboard the vehicle, a no start event history for the vehicle based on the determining by the computer processor disposed onboard the vehicle as to whether a no start event has occurred over multiple vehicle ignition cycles for the vehicle, wherein the generating of the no start event history is performed by the computer processor such that the no start event history includes both (a) and (b) below, namely;
(a) at least one from among a diagnostic trouble code (DTC) or a UTC; and
(b) at least one from among (i) a position and movement of a cylinder unit of the engine of the vehicle;
(ii) a position and movement of a crank shaft of the engine of the vehicle;
(iii) a level or velocity of flow of fluid for the engine of the vehicle;
(iv) a position and movement of a cam shaft of the engine of the vehicle;
(v) a voltage of a relay of the engine of the vehicle;
(vi) a voltage of a control system for the engine of the vehicle;
(vii) a battery resistance of a battery for the engine of the vehicle; and
(viii) a starter resistance of a starter for the engine of the vehicle.

Abstract
Methods and systems for monitoring no start events for vehicles are provided. In accordance with one embodiment, a vehicle includes an engine, a sensing unit, a processor, and a transmitter. The sensing unit is configured to measure one or more parameter values for a vehicle after a request has been made to start the engine. The processor is coupled to the sensing unit, and configured to determine when a no start event has occurred for the vehicle using the one or more parameter values. The transmitter is coupled to the processor, and is configured to transmit, to a remote server, a no start event history for the vehicle based on the determining by the processor.
