My pontiac grand am wont start. it acts like its out of gas. but has a quarter tank in it. whats wrong?

Could be the fuel pump. You can have all the fuel you want in the tank but if the engine can't get it, then you ain't going nowhere.

How old is your car? When you turn the key to the 'ON' position, do you hear the whirr of the fuel pump engaging? You can check fuel pressure by turning it to the on position and checking the fuel rail. If you don't know anything about this then get a mechanically inclined friend, CAA, or get it towed to a shop.

my grand am did the exact same thing and it turned out the gas gauge was wrong we put gas in it and it ran fine. even though it says theres a quarter tank you should try putting more gas in it

I've had this happen before. Do you still have an intact pickup tube on your fuel pump?

my car is get to hot but it has water in it what could be wrong with it

I have a 2001 grand am se and this may sound stupid but it works. Put enough gas in it to give it at least 3/4 a tank. If there isn't enough gas in it it wont pickit up. I have had to put 25 dollars and mine and finally it cranked. But now mine is having bigger problems it runs out of gas or its not picking it up at almost a 1/2 a tank. It only runs out if I park it facing down hill and it won't run out on the road. I hate putting so much gas in mine and wandering if its ever gonna crank but it always does.
