Check the basics, electrical connections vacuum hoses ect..... Your truck has On Board Diagnostics (OBD2).
Is the Check Engine /Service Engine Soon light on? If so there will be information stored in the computer of your car which will be key in diagnosing whats wrong. A professional grade scan tool allows key engine sensors to be analyzed without having to do intrusive testing at each sensor on the engine. Engine needs fuel, spark and mechanical integrity to run. Need to figure which one you are missing.
