Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
You will need to get your truck hooked up to a diagnostic scan tool and check for malfunction codes ,
In your case this could be a problem with the cam or crank sensor being faulty .
But that is the most typical issue for your problem so a good scan of the system for malfunction codes will
clarify this issue for you .
Also a possibility is that the security system has locked you down if you have the system fitted ..
Again as said a code c heck will let you know what is causing you this issue .
Please remember to only rate my answer when you are 100% satisfied.
