May I suggest a locking gas cap. You could put a large piece of cardboard under your car and if there are any drops the next morning that smell like gasoline you might find the leak if there is one.

Check under the hood for a box containing your fusible links (they look like large blade fuses in most modern vehicles). The fuel pump relay only operates the fuel pump. It doesn't provide power to the rest of the fuel system. Odds are the fuse for the injection system is blown. The inside of the cover of most fusible link cases usually has a diagram which tells what each fuse is. The easiest thing to do is locate that fuse and remove it (with the vehicle off of course) and visually inspect to see if it's blown. If it is, simply replace it and see if that corrects your problem. While you're under the hood you might want to trace the wires back to their origin and check to be sure the harness is not rubbing or chafing against anything that might have caused wires to break and short. It's rare for those fusible links to blow without a reason.

sounds like you have a computer glitch. i would take it to any auto shop and pay 50 bucks so they can take a look at your e.c.u. (engine control unit) we had a similar problem a few years ago with our 1990 volvo 740 gle 2.3l station wagon. it was a glitch with the computer. got a mixed signal with the mass air flow sensor.

There is a speed sensor on the rear diff cover that may me shot, however it is regulated by hertz so the dealer is the best place to see if the wires are okay. That sensor can be costly.
