Name is Greg, My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back,

If the check engine light is "ON" when the engine is running then the management system has encountered a problem with the diesel injection system .

What you need to do is have the system hooked up to a diagnostic scan tool to check for malfunction codes ,
The malfunction codes will point you in the right direction to where the problem lies , could be anything from a Cam sensor to a TPS or MAF sensor ,
I suggest you do the scan as just replacing parts on assumption could become very expensive .

Need further assistance with this issue then please get back to me .
