Starting Mode

When the key is first turned On, the PCM will turn on the fuel pump relay for two seconds. The fuel pump runs and builds up pressure in the fuel system. The PCM then monitors the MAF, IAT, ECT, TP sensors and Ignition Control Module (IC) Module signal to determine the required injector pulse width for starting.
