DO NOT RUN an engine with a dodgy lift pump, if the diaphragm leaks it leads to sump dilution and ultimately a runaway diesel... BANG!

As long as it's not your car, run it. Have the current owner start it.
If a car is a non-starter at time of sale it should be sold as such (for much le$$).
When shopping for a diesel, put your hand on the engine before any start attempt so you know it is cold. If it's not, and you like the car, ask when you can come back later (tomorrow) to a cold engine.
