Is not advisable to buy any vehicle without driving it, especially without hearing the engine running. Its not usual for an old fuel pump to fail if its been standing for a long period. You shouldn’t have a problem with a new one, unless it’s one of the two relays. (one controls the power and the other the speed) On the UK model; one is in the
passenger side kick panel and the other next to the fuel pump resister under the hood.. As you probably know, to replace the pump you will need to drop the fuel tank.
