I have a 96 too and when i took the pump out a few years back it was like new in there so surprised by its deterioration.
Solder joints are likely fine as long as there is no damage to the cables but a reflow wouldn't harm it.
Fuel pump ECU is behind the passenger side back seats, have you checked that, a spare would cost about £36 from Banzai breakers on ebay.
