How do you start an engine after running out of gas?
The best way to start a car after it runs out of gas is with the ignition key after refilling the fuel tank.....LOL, no but on a serious note if you can remove the air filter housing to prime the "CARBURATOR" please do so with a 1/4 ounce of gas before starting , if it is fuel injected just fill the tank with at least a gallon of fuel, turn on the key and let the electric fuel pump pressure up the fuel lines with the fresh gas, this will happen rather quickly about 25-20 seconds with the ignition key in the on position, then crank the engine over to start it.Depending on the type of engine, there are several different ways. Withcarburetion, crank the engine for several seconds and then pump the accelerator pedal a couple of times. Continue cranking up to 15 seconds- anymore could overheat the starter. Let it rest a few seconds and try again. It should fire up. With fuel injection, just cranking the engine should let it start if the fuel pump is good. With diesel engines, there may be air in the lines. Some engines have a primer button that draws fuel into the engine. Some engines require the fuel line at the injectors to be loosened to bleed the air. THIS IS VERY DANGEROUS AS SOME FUEL PUMPS PUT OUT UPWARDS OF 50,000 PSI OF PRESSURE AND CAN CAUSE DEATH OR SERIOUS INJURY!Also remember on a fuel injected gas engine it is always best to let the key stay on in the start circuit, allowing the electric fuel pump to fill the fuel lines and fuel rails you may even hear the fuel pump relay sound off with the radio etc turned off during this process....when you hear the pump relay stop then crank it over to start because pumping the gas pedal on injected cars wont do anything for your car to start accept perhaps get a code set in the computer memory.
