Just wondering. Have you checked all of the fuses in the battery junction box (F1=BJB) and Central Junction Box (F2=CJB)?

1996-1998 BJB & I/P Fuse panel layout

Regarding the remote start. Just wondering. Is this a full remote start or a remote crank? If a full remote start, something has to turn the ignition switch on. I would double check the remote start wiring. Remember that the remote start unit will need to power up the PCM as part of the remote start procedure.
