Has a bcc though only thing I haven't checked is the ignition switch test light shows when key is turned to start position test light comes on ,. Cluster is out dome lights out radio out power windows out power seat out mirrors out , third row elect seats up and down work ,, engine turns over crossing solonid but no fire I'm at a loss on this one bought a code reader is my next test any clues,, oh lightning hit kinda close 10 minutes before the trk died maybe not connected thanks ,Mike

You say the instrument cluster is out ? You need to have a professional scan tool hooked up ,to see if all modules are communicating ! A code reader isn't going to be any help . If a module isn't communicating could an will bring down the Serial >powertrain control module (PCM) restraint control module (RCM) instrument cluster driver seat module (DSM) climate controlled seat module parking aid module central junction box (CJB) vehicle security module air suspension control module 4-wheel anti-lock brake/traction control (ABS/TC) module or stability assist module electronic automatic temperature control (EATC) module four-wheel drive (4WD) control module power liftgate module tire pressure monitoring system module Principles of Operation

Your best bet would be to take your vehicle to a qualified repair shop Or the ford dealer .
The vehicle has three module communication networks:
Well , the instrument cluster not working stands out for me !

The instrument cluster has a microprocessor an is on the serial data network . This can bring down the data bus circuit an cause all the problems your having . The only way to find out what's going on is to have a professional grade scan tool hooked up .Your vehicle has several modules , Engine - PCM , Air bag , anti-lock brakes , VSM- vehicle security module ,Instrument cluster etc.. Any one of these could have internal problems causing communication problems ! When you turn you key to start , it sends a crank request on data bus to the PCM which in turn energizes the starter relay ! This is a very complex system , electronics !
