Fuel tank supply pump may still be OK, There is a test port on the VP44 injection pump to read supply pressure from pump. I would start by testing tank pump supply pressure. If the VP44 had gasoline run through it.. the pump is galled and can not make pressure to open injectors [I'm betting] which means, no fuel to engine. IF I recall... there is a test port on the fuel rail to check that... at the dealers.. New VP44 injection pump is in the $3,000 range.... ouch
