1997 f250 4x4 460 ci. will not start sometimes and dies when moving after a while driving
I have replaced dist. ingition. module,computer and coil and when it wont start I unplug the spout conector it starts
That is usually an indicator of an ECM starting to fail, but check the ECM power and grounds pathways and replace the ECM relay, Fords do have problems as they get older with loss of ground and relays getting weak. But all of the Fords that I have came into my shop that did what yours is doing wound up getting a new ECM. Hope this helps.
