Pretesting Inspection

If ECI system components fail, interruption of fuel supply or failure to supply proper amount of fuel for engine operation will result. The following conditions will result: engine is hard to start or does not start at all, unstable idle and/or poor driveability. If any of these conditions exist, perform inspection by self-diagnosis and basic engine checks (ignition system malfunctions, incorrect engine adjustments, etc.). Then inspect ECI system components using an ECI checker.
