02 Taurus cranks but won't start
Having problems uploading photos, so I will try an tell you some of the color codes of the wiring. crank sensor feed wire is grey, the return signal is dark blue. your cam position sensor has three wires an the coded colors are as follow, black/white, red, dark blue/ orange. I hope this will help you. I'll keep trying to up load pictures.
Could you tell us where the white wire with the lt blu tracer comes from? It feeds power to the coils, but don't know what voltage it should read until we know where it is supplied , it could be 12 volts and it could be less . It could come from the PCM, but need to know what else is on that circuit. Once we know that, we can check that wire at the coil and be sure it is getting power.
Once we confirm that, we can see if the signal from the crank sensor to the PCM and then to the coil is providing the ground to fire the coils.
Thank you for your assistance and providing the diagram.

I am pretty sure the coils are fed Vref voltage (12 volts) from the PCM power relay, but need to confirm that from the diagram. If that is the case, with the key on, there should be 12 volts available at that white with the blue tracer wire at the coli plug. That is the next check I would suggest.
