Yes you will want to verify GPs are energized during pre-start. Do you have a VOM?

But even if the GP relay or wiring was disturbed, it should have started up immediately, as the engine was then still near operating temp, not requiring GP.

Verify the fuel cutoff solenoid is getting +12VDC when the key is in start and run positions.

Does not make sense to me. Explain?

Did the engine immediately stop on impact or did it continue running for some time? Did it leave an oil puddle? Is the oil pan intact?

More of a pressure hose than vacuum. It transmits turbo-induced pressure from the intake manifold to the top of the IP diaphragm that moves the ramped fuel pin to increase the amount of fuel injected under boost. Disconnected it would reduce performance under boost situations (generally during higher revs, more throttle).
