2003 Saturn L200 vapor lock?

fuel pump

I don't know if this will help you or not, but I've had several friends with Volkswagens & have run across this problem after they ran out of gas.
the fuel line ran close to the exhaust manifold & the gas would vaporize in the fuel line, causing a vapor lock in the line, starving the engine of fuel.
the fuel line had to be taken off at the carburetor & fuel sucked up through the line.
future problems were eliminated by rerouting the fuel line.

Well it could be numerous if things but you want suggestions...So here's mine..Your gas tank might be vapor locked...This is caused from over filling your gas tank with gas over the years..Its when the pressure in your gas tank becomes greater than your fuel pump. It wont start until the pressure in your gas tank becomes lower then you fuel pump...Sounds crazy...This got me once...I didn't understand it...A lot of people (including me) Go to the gas station and get that extra 50 cent after the gas nozzle clicks off...over time that extra gas will run down the vapor lines intended to burn fumes....Like when you fill a gas can to cut your grass...If you sake the gas can it builds pressure and bows up. But with time that pressure will go away...Well saying that...Your gas tank needs to vent to....So your car burns not only gas but fumes...If you keep over filling your car with the extra gas it cloggs up your vapor canister intended for fumes or vapors...The gas will will go into that canister and clogg up the charcoal that's inside it. (Breaks it down) then the vapors can't get to your carburetor where it supposed to burns it. So what happens is the pressure in the gas tank becomes greater than your fuel pump and then car won't start..Are you with me? Lol Its crazy..Putting a different gas cap can cause the same thing...Simple test...When you open your gas cap to get gas.. Do you heat air sucking in.. Yes you can hear it....A lot of times loosening the cap let's the pressure out and the car will start right up.....Thus might not be your problem but worth telling at the gas pumps to other people..... Just trying to help

Fuel filter is clogged. Or the catalyst converter is clogged.

Without knowing if there are more things happening, noises, clicks, whirr sounds, or even how hard you drive it...

It typically sounds like a bad or clogged fuel filter... Although I've had some cars do this in the past, once they were heated up and had to wait an hour ow two to start again... that generally meant the fuel pump needed to be replaced.

This is called a Vapor Lock... and try as you might, they will not start

So, before you start going through quite a few external sensors, idle air control motors and egr valves and etc, etc at 85 dollars a pop...

Considering changing the FUEL filter and pour a bottle of gas drier in your fuel tank. You could have some condensation in your fuel and it may be as simple as that.

However if this dont help or the problem starts happening again, I would replace the fuel pump.

Good Luck and Happy Motoring

Sounds like a ground issue...Check your battery post and ground wires..Also could be vapor locked..Next time it stalls loosen your gas cap...If you here air suction going back into your car and if starts up that could be the problem..Your vapor canister is clogged causing the pressure in your gas tank to become greater than your gas pump...Then the car shuts off until the pressure in gas tank goes back down..

you will need to remove the air cleaner and pour a small amount of gasoline in and get to start, the fuel rail is vapor locked and needs the engine running to pull this air pocket through the fuel rail,it may take more than once if the fuel filter in the rail got dried out between the gas tank and engine

Transmissions are tied into the function of the newer Saturns which can give you drivablity problems. You should take it too an authorized dealer to have it diagnosed just for that reason alone.

either the fuel sender in the gas tank is bad or the bcm is bad,most likely sender

Put the gas in the tank, let everything settle, turn key off, then back on to on position, but NOT start. Let the fuel relay engage the pump and draw some gas pressure. Give it a good minute and it'll start right up.
