The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No. 1 is on its compression stroke. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors.
On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single "vane" spinning around by virture of a synchronized shaft which is driven by the camshaft.
The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

The camshaft sensor is located right above the crankshaft pulley on the passengers side of the front cover of the engine. It will be a 3 pin sensor either gray or black in color. There is a pointer that is attached to the sensor and it is either gold or silver in color. There is also a recall out on this camshaft sensor. If the color of the sensor is black then it should qualify for the recall. If you get in touch with a Ford dealer they should be able to help you with your recall if the sensor is black since it is a safety recall. As far as your exhaust pressure sensor it is located on the front of the engine right by the heater core hose a little to the passengers side of the center of the front of the engine. there will be a tube attached to the bottom of the sensor that goes from it to the front of the exhaust manifold on the very front of the passengers side exhaust manifold.

The code will tell you which O2 sensor it is.
The code will point to either bank 1 sensor 1; bank 1 sensor 2; bank 2 sensor 1; bank 2 sensor 2.
From what I remember with a focus, it should only have 2 sensors, sensor 1 will be located before the cat, and sensor 2 will be located after the cat.

Testimonial: "Thanks for your help, now we will attack the problem."
it sounds like you have bigger problems if your car does not crank(turn over) then your timing belt could have broken and the one piston could be hitting a valve causing it to be locked up.normally when any sensor is bad car engine still cranks it just doesn't start.
