You're going to need a code reader. Without some clues you're going to bankrupt yourself throwing parts at the car and hoping something magically works. Sometimes its not parts, but maintenance things like making sure connections are tight and grounds are clean. Also the timing chain tensioner fails on these engines and when it does the valves hit the pistons and the engine is done. Check that out before you drive it more. (I speak from experience)
