Ford Ranger 2013 200000 miles
My ford ranger cranks ,starts and then cut off again. I replaced my old engine with another engine,turbo charger,throttle board.It usually cranks and then starts again after a few minutes or hours. Sometimes it goes into safe mood but after a few minutes it removes itself again and sometimes it stops whilst trying to reverse it. What might be the problem?I've tried putting it on the machine bt the only issue being shown is to do with the rear speed sensors but my mechanic believes this has nothing to do with it cranking,starting and then failing to start again whilst showing a battery light and oil light switch light on the dashboard.
