My truck shut down the other day going down the road had it towed it will spinn over but will not crank. Driver claimed no issues but when shut off blew smoke out of left side and had oil on left back of engine. Oil level is good and coolant is good . The truck will hit if I spray brake clean or gas rag on breather. I am assuming computer has it in fail safe and has shut the fuel off. Any ideas where to start troubleshooting this problem. the onle codes where P244b and P200c.
