Answer
Hi Mike,
Try disconnecting the battery briefly to erase the old fault code. Then reconnect and try to start it. Then if it won't start check for fault codes again. If you still have the crank sensor code (what is the #?) then check to see if you have 5v on the orange wire at pin 3 of the sensor plug when the ignition switch is in the run position, and also check the continuity of the dark blue/white signal wire pin 1 to pin 35 and the black/light blue wire pin 2 to pin 27, both of those at the engine controller plug.
Sorry for the delay in responding but I just found your quesition in the 'pool' to which it had been referred by Kevin.
Please 'rate' my answer (see below).
