I replaced my ecm cause the car would die whenever it was hot,for no reason,a jolt or bump would stop it dead in its tracks.It turned out to be the ecm wiring was bad,they route it across the water pump,and every one of them does it.I went to the junk yard,and they all had bad wiring in the exact same spot.about ten of them i came across the wires leading to the ecm were fried about a foot away from the ecm plug.i had to take several things off just to get to where the wires were bad.When it dies again,grab the ecm wires,and give them a light tug,or giggle,and try it again.
Unfortunatly i couldnt find available wiring for one of those,so i went to radio shack,and bought some shrink tube,and wires,and soldered my own.
