I looked through shop manual and found no mention of a fuel cut-off switch.
However, the main fuel relay 2 (MFR) serves this safety function in earlier models. If engine is stopped (accident) w/ keyswitch On, the MFR opens denying power to the fuel pump. This prevents fuel pump from feeding fuel to a potential fire.
If you turn keyswitch to ON, you should hear the MFR click (driver's kick panel) and fuel pump run for 2 secs and cut off. If silence, then either a bad fuse (fuse 7 under-dash), bad relay(Lower row, rear relay on kickpanel), or ECM is denying ground to the MFR preventing it from engaging. It could be that an accident may cause the ECM to prevent running until reset. Resetting will likely require a scanner.
PS I moved your post to a more appropriate section.
