I was rear ended and now my car won't start, I was told there is an inertia fuel cut off switch to look for but I can't seem to find it, when I turn the key the fuel pump does nothing

 

Check all fuses.
Check the fuel pump ecu. try the 12v mod.
Check for pinched wires.

 

Odd Toyota quirky factoid:

These fuel pumps don't prime in the ON position. They prime in the CRANK position. Don't ask me why. It drove me nuts when trying to diagnose my no-fuel situation when 1JZ swapping.

Bypassing the fuel ECU fixes most issues.

 

Was actually something simple, I opened up the gas tank and noticed that the fuel pump got disconnected. Car is fine thanks for the suggestions.
