does it go off if u un-plug the switch? if u un-plug it and it goes out I think that you have a bad switch. hit a gunk yard and pull one out for 10$..Matty

Well, of course premium is HIGHLY recommended, but it is not necessary.
You can use regular grade in your engine and it will not harm it at all. Modern engine management systems have knock sensors that detect lower grade fuel and make the necessary adjustments to your timing and fuel delivery systems.
All you will notice is slightly slower acceleration and a slight drop in engine horsepower.

Hope this helps...

If it start then it's a defective neutral safety switch.

Shift to PARK and shut off engine.
