Hi there. It’s possible that you have an air / fuel mixture issue that could be causing the hard to start problem on your Isuzu. Some components, including the EGR valve, the throttle body itself and fuel injectors can become clogged with excessive carbon build-up cause this problem as well. In order to effectively diagnose this problem, you should have a professional mobile mechanic complete a car is hard to start inspection.
