1689 is one of the death codes for the vp44... (associated with vp44 electronics failure)
but it could also be caused by a bad ecu, or a bad fuel system relay, bad drivers side ground, etc...
I would check the ground and the relay first.
1693 means there is another code in the PCM that you will need a code reader to retrieve.
