I think that the idea is to shut down the pump(s) wi= th the engine running. The injectors will continue to do their thing, &= the engine quits when pressure drops too low to flow through the open inje= ctors.

Shouldn't shutting down by cutting power to the fuel pump = relieve the pressure, though?
