    ok guys so my wife was driving her car the other morning and it was fine. She parked it at home and a few hours later no start..So far what ive done checked for spark and have none ....pump is not running while turning the motor over.. So i changed out the crank sensor thinking that would be the easier thing to try.. no change then i noticed there was no CEL on so i tried to run the hand help on it and it says "no link" so im guessing my ecu has no power...i have an extra ecu so changed it out still nothing changed....i unplugged the abs box still no communication...the relay by the ecu wich i was told is the one controlling the ecu load and power is running through once the key is on....im leaning more towards electrical issue but i have no idea....im not good with electrical at all and i cant find the wirring diagram for the AWM motor (my repair manual does not show that motor code for some reason) if any one can help me with any thing that would be awsome...a wirring diagram would be great thank u

    nowhere

    Have you tested the said relay correctly and know for sure?

    Could be an electrical issue with the port itself.
