I believe the safety switch is designed to sense an accident where the vehicle is either on it's side or upside down. Of course ... you never know what you'll run into with a junker but if the car is sitting level the safety shouldn't be a factor in the mix.



Next time you go to start your vehicle turn the ignition to the run position but not the crank position. If you listen carefully you might be able to hear the humm of the fuel pump coming on. Once the fuel line at the rail has come up to the correct pressure it will cut out.
