No spark to engine. 3.0 flex fuel motor. Changed plugs,wires and coil. Still no spark. Engine is getting fuel. Want to know which wires at the coil pack runs to the crank sensor and which one runs to the cam sensor.
Follow this link and take your pick of many diagrams for the crank sensor. http://images.search.yahoo.com/search/images?_adv_prop=image&fr=yfp-t-900&va=2000+ford+taurus+crank+sensor+wiring+diagram

Hi.
The PCM is located in the rear right corner of the engine compartment, sticking to the firewall:
The PCM can be replaced with a new or used god-working one. In both cases the PCM must be reprogrammed using a Tech 2 tool that costs about $3000. The operation is done at the garage.
The PCM is unlikely causing misfire on a single cylinder. Check wires going to spark plugs. If the coil is getting no 12V on the ignition side check ignition. It is strange that one coil has no power, the engine usually does not start when that happens because the same coil gives power to spark plugs on different cylinders.
Check if there is a capacitor fixed to the head aside the coil (there should be one). It should be cylindrical and one inch long, held by a single screw and located aside the coil. If there is a capacitor, that must be replaced with the coil. If you have not replaced the capacitor that is probably involved in the problem.
If you have already replaced crankshaft position sensor, check crankshaft position sensor harness in PCM. I uploaded here the bulletin with CKPS to PCM testing:2003 Taurus CKPK PCM testing.
Test the PCM and CKPS connectors. Check again voltage to coils and spark plug cables. I understood that spark plug cable nr.3 has no spark from coil. Check DC in from ignition to coil.

I personally would check the fuel pressure. Then I would go back to the coil. I have seen brand new bad coils out of the box. The symptoms of a loss of power point to this component, especially if the car idles well, but loses power when accelerating. Please do not rate this reply - we all are left to grasp at straws since you have changed pretty much everything. Good Luck. Please post the final fix of the problem.

Run a compression test on the cylinders.If reading is low on any drop a little engine oil into the pot. If compression rises you have compession ring problems. Remove all plugs before you try this and place leads away from engine.
