Will not start after running out of gas

Use a gage and check fuel pressure. 53--59 psi, key on engine off.

Put at least five gallons in the tank, then cycle the ignition switch on and off a couple of times before trying to crank the engine. The fuel pick-up screen sits in a bowl so the last few gallons of gas do not run to the side, away from the pick-up when you are going around a corner. That bowl will self-fill later, but to get it started, you need to have enough in the tank for the gas to overflow into that bowl so it will get into the pick-up screen. On my minivan, that takes five gallons.

Also, listen for the hum of the fuel pump for one second each time you turn on the ignition switch. If you do not hear that, the pump motor might have burned out. They are cooled by the gas in the tank.

In the future, you should start a new question specific to your car, engine size, mileage, and list of symptoms, history, and clues. When you piggybacked on this one, it simply shows up on our list of questions awaiting a reply from the expert who was in the private conversation. The expert and the person asking the original question are the only two people who got a notice that an addition was made. I only showed up because I thought I could learn something. All the other experts know this is not their conversation so they will not even read what you added or have the chance to respond. That will not get you the help you need. This is different, (and better), than on other sites where anyone can chime in and confuse the issue.
