The 97 EVTM shows from inertia switch to fuel pump is wired pink/black stripe.

Theres a connector that appears from the diagram to be under the drivers side floorboard.

If you open that connector & a new fuse does'nt blow, theres a short in the PK/BK between there & the pump or possibly the pump is locked up.

Have you tried giving the gas tank a good whack with your hand? Sometimes that will bring a bad pump back to life temporarily.
