First make sure you actually did run out of gas (I know this may seem obvious but ck). Your fuel pump, I believe like mine, is easily accessed under the trunk carpet. You need to make sure that the pump is running (you should hear it). Next, change your fuel filter (should be under the car, underneath the rear passenger seat) , then check the fuel pressure with a tester (available at most auto stores). Check for engine codes on your dash by using the technique described in your Service manual (not owners manual). Your Bentley or haynes manual should easily guide through these steps. The books are pretty good at taking you through the troubleshooting.
