Starting Mode
WARNING: This page is about a different variant/trim than selected.
When the ECM detects reference pulses from the crankshaft position sensor, the ECM will enable the fuel pump. The fuel pump runs and builds up pressure in the fuel system. The ECM then monitors the manifold absolute pressure (MAP), intake air temperature (IAT), engine coolant temperature (ECT), and accelerator pedal position (APP) sensor signals in order to determine the required injector pulse width for starting.
