Need help just wondering if a 93 ford thunderbird has a safety fuel shut-off switch.

I think the only safety switch in the starting circuit (which just engages the starter motor to crank the engine over) would be the neutral safety switch. But if you have the anti-theft system, that will inhibit starting while honking the horn and flashing the headlights, too.
There is an inertia switch in the wiring to the fuel pump which could trip with a large bump, but it would only shut off the fuel pump, and not affect the starting circuit.

The neutral safety switch wiring would be found in the wiring to the Transmission Range sensor, which also needs checking.

93 Octane Premium Fuel

The only vehicles that I know that have a fuel safety shut off are the Fords.G.M.vehicles do not have safety shut off switches.Good luck.

Here's a pic of the PCM location...

In the past, waiting for the fuel lines to pressurize was the only way to start fuel injected cars. Newer cars are designed to keep the line pressurized after you turn it off, and there is no need to pressurize upon restarting. Seem like your vehicle is losing the pressure gradually after shutting it off. Gasoline pressure can only be lost 2 ways: 1) A broken line, with fuel dripping to the floor, which, obviously you can see and smell, or gas going back into the tank due to a faulty pump or pump installation.

its in the back of the car trunk or hatch left hand side push the red button its called an inertia safety switch

the ignition module is attached to the distributor body, see photo below.

check you fuel pump relay or your fuel pump shut off switch

If the same as on a 93 the wiper motor has two connectors.

Connector A (motor):

wiper switch to motor (high) - dark brown / orange
wiper switch to motor (low) - white
ground - black

Connector B (park switch):

wiper switch to motor (park and return) - red
wiper switch to motor (park return) - black
ground - black

Hope this helps.

Here is the recall info.

The vehicles affected by this recall are certain ‘92 & ‘93 model year Ford Thunderbirds and Mercury Cougars. The problem; the headlights turn off, then come back on after driving with the fog lights on. Ford is replacing the headlight switch and if necessary the electrical connector for the headlight switch. Repairs for a safety recall are to be performed at no cost to the vehicle owner, even if you are not the original owner. In addition, if the headlight switch was replaced before the recall, the owner is entitled to a refund for repairs. But the owner should still bring their vehicle in for inspection. Why? The replacement part may not have been of the new design.
