Based on your description, it sounds like the ignition switch is bad--scanner can't communicate to the PCM (asks if key is on); starter motor does not crank, when the ignition switch is turned to START (only when the starter motor is jumped); and the engine suddenly died at a stop sign. To me, the weight of the evidence points to a bad ignition switch.

Not saying it could't be but I have starter relay activation,all other options too ,have you ever heard or seen an ign switch failure on this model??

Ignition switch problems are common with Hondas, but not Fords, on this site. Still, I would remove and check the switch for signs of wear, pitting, or melting. I would also check that all ignition switch harness connections are secure. It would be good to apply dielectric grease.

Are you saying the starter solenoid works with the ignition switch?

Anything new?

I installed known good ign switch same result .You are misunderstanding my questions ,you are guessing what my problem is I can do that! I ask if you had seen this problem... I am not a parts replacer I have never used that type of method to make repairs and never will.Sorry I can not accept any more guesses from you.Thanks anyway! Doctors use this type of diagnosis but there patients sometimes DIE! Unexceptable!

Your are an ingrate. It's best for you to go somewhere else. Unbelievable!
