if your scanner read it and there is no 5 volts sense then its time for another one.
terminals 13 and 26 are ground. Leave computer plugged in and check those two wires with the ohm meter to see if they are grounded. 13 and 26 are both black.
Terminals 12 and 25 are your 12 volt wires. key on and they should be hot. 12 and 25 are both red wires going into the pcm
So if those 12 and 25 show hot and 13 and 26 show continuity to ground. then the pcm is bad.
fuse number 7 is the pcm fuse. but you said it had power so I know you looked at that.
my bad flag troll will be by shortly to give me my bad flag :)"
