Give us some details. Does it crank? Battery voltage? Replaced parts?

It's cranks. Battery is good. Replace crankshaft sensor. Camshaft sensor. The whole distributor. Fuel pump. Fuel injectors. Mass air flow sensor.
Spray a little starting fluid down the throttle body. It should run a few seconds on that. If it does, you have a fuel problem. If it doesn't, check for spark. If you have spark and fuel (the starting fluid) but it still won't run it's time to do a compression test. If all cylinders test very low or zero it's jumped timing. Hope that helps! Jim
