When I first get in the car it will start after sitting for hours, but after I drive it and get back in it and it is within an hour or two it just turns over but won't start. I have to pump the gas and wait a while before it will start. And also when I am putting gas in the car I have to pump it really slow or the pump will click off. If this is the fuel pump can you tell me if it is in the gas tank and about how much one would cost for this car. If this isn't the problem can you let me know what it is.

I can't be sure without a few checks of it is the fuel pump. I assure you the pump isn't stopping the fuel from entering the tank.

First, when the car won't start, check you need to check for spark and fuel to the engine. One will most likely be missing. Here are the how to steps for checking both.

If you find there is no fuel, open the fuel cap to see if there is a change in fuel pressure.

Next, the problem with filling the tank can be one of two things. First, there is a check ball at the end of the filler tube where it enters the tank. Its purpose is to prevent fuel from leaking in the event of a rollover. It could be sticking, thus preventing fuel from entering the tank. Also, if you ever noticed, there is a breather tube next to the filler tube that can be plugged. One of its purposes is to allow air to exit the fuel tank when being refilled. If it is blocked, the tank remains full of air and the fuel has nowhere to go.

Let me know what you find on the no start situation so I can further direct you on that issue.
