On a 2005 ford sport trac I have no spark from the ignition coil. I replaced the 6 coil pack and still the same. I know it could be the Csp sensor or the PCM. I got a 0320 code originally. Ineed to check the four wires feeding into the coil pack but Idon't have thee wiring diagram. I can use some help.

 

I don't have time currently to research the P0320 or the wiring diagram, but a Crankshaft Position Sensor could cause a no spark condition and has been a known issue in the past years.

I had the same symptoms (but didn't check for codes) on my '97 and it was either a bad connection on the crankcase position sensor or a weak battery. I repaired/replaced both so I can't be sure but I think it was the battery. It has enough power to crank the engine around but the voltage was below the limits so it wouldn't make a spark. I suggest checking the battery with a hydrometer and see if you have one or two weak cells.

 

Thanks for the quick replies. I was able to get the wiring diagrams for the 2005 sport trac from Mitchell 1 for 12 dollars on line for 1 week. I am getting the 12 volts to the primaries on the three dual coils on the first wire to the input plug to the coil pack. the other 3 wires provide the grounds to the three that when the PCM breaks off the high voltage is generated at the secondaries which go to the plugs. The battery Voltage is ok because just charge it So now it I can trouble shoot where the problem is. Either wiring or bad CKP sensor or bad PCM.
