I have had the exact same problem. There is an ignition lock that probably went off. There is a fuse box under the hood. The fuse that says ignition on it pull it out and put it back in. This should reset the ignition lock. Its a safety feature because the car thinks that someone was trying to tamper with it.

Are you certain that the engine is getting fuel? If not, then you will have to verify that there isn't any blockage in the fuel system to prevent the fuel from reaching the engine. If fuel is reaching the engine, try the following
1. Check compression values for each cylinder.
2. Inspect electrical circuitry in the distributor assembly (slack wires, broken wires, dmaged rotor etc)
3. Check to see if the timing belt was not severed. This belt transmits the drive from the crankshaft to the camshaft. If the belt ius severed, the camshaft cannot rotate in order to open the valves

Hello oldiro: My name is Roger and I can help. From under the vehicle look up between the transmission and the side of the block. Mid motor above the pan rail there is a bolted in sensor. This should be the crank sensor.It will have two wires plugged in to it. Please rate this answer as this lets us know you received the information you asked for. Should you need further help please just ask. Thank You for using FixYa. Roger
