II. Fuel pipeline and Circuit Fault for Hard Engine Starting
Hard engine starting indicates that starter can crank but fail to start the engine, or it may take multiple
consecutive starting efforts or long time rotation to successfully start the engine. For hard start fault, make
sure whether it occurs at cold or hot status or regardless of the cold or hot status.
1. Symptom
When starting, engine cranks at normal speed, but it takes longer to start or fails to start although cranks.
2. Causes:
a. Air cleaner is clogged;
b. Intake temperature sensor fault;
c. Water temperature sensor fault;
Engine can not start
Check the starting system
Check the high voltage spark
No high voltage spark or weak spark
Check the ignition system
No sign of cranking
Check the electric fuel pump for operation
Check the electric fuel
pump and its control circuit
Inoperative
Check the injector
Check the control circuit
