just had this problem in a 2002 Mercury Sable 3.0 and the problem was the crank sensor that sits by the injectors on top ,you have to replace the shaft and sensor both,it cost about 60.00 for both parts +labor and if you do it your self make sure you mark on how it comes out to keep it in time has to be put back in the same way it comes out... kramer2234
