I have replaced pcm and ignition(matching) and the van will start one minute and not the next, It turns the starter on but wont fire, also I have dashes (---) where my kilometers should be, and my radio turns of and on with no key in the ignition any suggestions?

 

Maybe,,,,,,,,,,,,, a parameter reset of the replacement PCM might help get rid of some of those problems.

 

have someone coming to do that tomorrow I hope that solves it.
thank you

 

I also forgot to mention the van worked for a week or so with the new pcm with no issues.

 

the pcm does not seem to be at fault, the tech was unable to connect to the pcm and there were multiple network failures, anybody have any suggestions from here?

 

Just a thought, but have you checked and cleaned all of the multiple grounds used by Ford on the Freestar for communications? A bad gound can cause all kinds of weird things to happen. I had a bad ground by the driver's side kick panel that was actually causing my van to randomly start (yes, engine fire up and run with no key) by its self. Took the Ford Tech and Ford Engineers over a month to figure that one out. I once left the ground off that's located by the A/C accumulator when I repaired my A/C and the side doors opened by themselves and would not stay closed along with the headlights came on and stayed on. There are several grounds located under the black radiator support cover.

 

that was one of the first steps I took to no avail, the van will start and run for a minute and then shut down, someone suggested that I change the universal bus controller any thoughts?

 

I'm not positive on this one , but you might wanna be careful doing that , you are liable to wind up getting internet service !

 

Sorry "multifunction module" part# 4f2t-15604-cl

 

Do you get moisture in the pcm connector?
