What are the causes of the Corolla engine EV control system malfunction?

[VonKatherine]

The causes of the Corolla engine EV control system malfunction are as follows: Starting system failure prevents the engine from turning or turning too slowly: Insufficient battery charge, loose or severely oxidized battery terminal clamps; blown main circuit fuse; ignition switch failure; starter motor failure; open circuit in the starting line or poor contact of the line connector. Ignition system failure: Poor performance of the ignition coil, resulting in weak or no high-voltage spark; ignition device failure; incorrect ignition timing. Fuel injection system failure: No fuel in the tank; fuel pump not working or low pump pressure; fuel pipe leakage or deformation; open circuit relay disconnection; poor performance of the fuel pressure regulator; excessively dirty fuel filter.
