Mondeo tddi won't turn over fail code u1262 (j1850) bus communication fault b911 b912 b913 b914 b915 b916

Any help to figure out why it won't start would be really appreciated,worked fine the night before and now nothing,plus digital temp just comes up with lines across now ?

Does it attempt to turn over at all?

instrument cluster faulty maybe? Would disconnecting the battery for an hour clear the codes and let it start?

No wont attempt to even turn over iv cleared the codes with my f super but come straight back on,could this be outside temp sensor?

Turned out to be an engine fuse box relay

Can u please describe the reley position/number/color? I have exactly same problem with my mondeo mk3 2003 1.8 gasoline 81kw. Engine won't crank,not a sound. My odometer and temp display is showing normal,but after a few seconds is showing dashes -----. I already checked fuses but nothing wrong. If i manualy engage the starter relay,the engine crank,but not start. Immo led is off after turning the key. Strange one: if i disconnect the cable from the ecu/pcm, there is no change,as if the ecu isn't there. Possible ecu is dead??? Thank you

Ok,i solved my problem today. My ecu is dead. I tryed with another ecu and started at first turn.
