Car keeps cranking and wont start. i replaced the distributer cap and rotor. new ngk spark plugs and new wires. when i turn the key on i can hear the fuel pump priming. and i can hear the main relay clicking. when i opened the oil cap and started teh car, everything looked good. I was drivin it one day, and it jsut shut off, and now it wont turn over. Ive been lookin all over the internet, but cant figure it out. Please give me suggestions..
