Jump on the above, at least a hot wire kit and pick a pump you want. When wiring make your grounds perfect. When the tank is out inspect inside for rust and flush.

Chek the tank vent while doing the work.

Check the fuel pump relay on the passenger side fender . Tap on it a few times while someone is trying to start the car . Also put power to the grey wire behind the alternator ( it will have a connector on it and goes to nothing ) that should turn on the fuel pump without trying to start the car .
