car ran out of gas i put gas in take.It stared then stopped. Now it will not start

Make sure you put a couple gallons of gas in the tank. Depending on where your fuel pick up is located in the tank one gallon may not be enough. Since the car was run out of fuel there could be crud/ debris in the fuel pick up screen from the bottom of the fuel tank. Try filling it with gas and letting it sit 15-20 minutes. This will allow any debris to settle back in the bottom of the tank. Try starting it. I hope this helps.

Air pocket in injector rail. Turn on key to run without starting car, do this COLD, or fire risk, There is a nipple for testing fuel pressure, gas will come out when nipple is opened without pressure gauge on... sometimes the air can be bled out of that.

Open the hood of your vehicle and locate the fuel rail. This is normally located towards the back of the engine bay, on top of the engine towards the firewall. Locate the Schraeder valve. This valve looks like a valve stem that you would normally find on a tire. This valve is a bleeder valve that will release pressure and purge air from the system if you loosen or remove it. On some vehicles, you may be able to press down on the valve to release pressure. Place a rag over the end of the valve, and either loosen the valve with the wrench or depress the center of the valve with the flat head screwdriver. You will hear air coming out of the valve, but you may also notice gasoline spraying out also. The rag is to prevent the gasoline from spraying all over the engine bay. Re-pressurize the fuel system by shutting the valve and turning the ignition to the "on" position (the position just before the crank position where you attempt to start the vehicle). You will hear the fuel pump prime the system. When the pump stops, turn the ignition off, and turn it back on again, and allow it to pressurize the system again. Repeat this process several times. Repeat steps 3 and 4 again. This should ensure that your fuel system is properly bled and is working as it should.
