Engine won’t start Checkpoints: Check Battery Voltage Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check ECU connector connected properly Physical check Step 2 Check injector connectors are connected properly. Check the continuity. Physical check Step 3 If the problem persists, replace the ECU Circuit Description: ECM injects fuel in the cylinder with the help of injectors. ECM monitors the engine sensors and determines the precise quantity of fuel to be injected. ECM turns the injector on for a precise amount of time referred to as injection pulse width or injection duration to deliver the calculated fuel in cylinder. Injector is turned on through high side driver (supply) as well as low side driver (ground) present. Circuit Schematic Diagram:
