I did this 2 or 3 times with carbureted cars, but I'm sure the same
warning would be given for those cars if they were sold new now.
However it worked well. I only needed to do this when I ran out of gas,
and after a few times, I learned** to turn the engine off the moment it
started to show signs of running out of gas, so that when I got a gallon
of gas and tried to restart it, there was still gas in the gas line and
it always restarted after a few seconds.

Clearly, wih a current, fuel injected engine, gas poured into the air
intake will not be injected into the cylinders, but it may be slightly
vaporized and sucked in with the air.

So my question is, will pouring a little gas into the air intake help to
start a car that has run out of gas


**Actually there were three stages:

1) At first, I'd pour the whole can of gas into the gas tank, and then I
might run down the battery or risk overheating the starter motore before
the car started. Maybe I had to get a jump, I can't remember.

2) I learned to not pour eveything into the gas tank and save some for
the carburetor. I'd guess between a quarter and an eighth of a cup,
maybe less. That always worked well. I think I tried starter fluid
earlier, but maybe the car didn't run as long on starter fluid as it did
on gasoline.

3) I learned to turn the engine off the moment it started to show signs
of running out of gas, and iirc I didn't need to pour anything after
that.


On a fuel-injected car, (or any with an electric, in-tank fuel pump)
you should only need to turn on the ignition, wait a few seconds for
the pump to pressurize the line, and then start the motor.

You might even hear the pump running, and then stop when pressurized.

I had a 1956 Dodge p/u that had an electric, in-line pump, and it
would start almost instantly upon turning the key. Not like most
carbureated cars that would take 3 or 4 turns to start while the
mechanical pump re-filled the fuel bowl.


That may work or it may not. A lot of newer cars will only run the
fuel pump when the starter is engaged or when the computer detects
that the engine is actually running. I found that with a GMC pickup
and a Chrysler LeBaron (just looking at the wiring diagram and theory
of ops). The good news is that an electric fuel pump moves so much gas
that you might not notice as long as everything else is working OK.
Squirting a little gas in the intake will get the motor to spin a
second or two if the other 2 parts of the equation are present.
