This is a good one!! These switches should never really wear out from over current through the contacts. The switch acts as ground path for the windings of the fuel relays, which is a much lower current. It does not act a path for the current through the fuel pumps. Not unless the wiring had been modified by some fool who had no idea what does what.

Make sure your ground strap from the transmission to the chassis is secure, clean and well grounded. If this connector is not grounded well, you will have other circuits using ground seeking the path of least resistance, which very well could be through the IC pressure switch.
