First, if your car still runs, pull the fuel pump relay, and start your car, letting it run until it dies. This will depressurize the fuel system. Then you must support the fuel tank, and take loose the straps that hold it up. Slowly lower the tank until you can unhook the tank filler hose and overflow hose by taking the clamps off and sliding the hoses off. lower it some more, and unhook the fuel lines; they require you to insert a special tool around the edge of the connection, however this can be improvised with screwdrivers or a piece of plastic or metal bent into a C shape. Next unhook the wire connection. Once you get it down, it's easiest to empty as much fuel as you can; as this will help you get it back into place. The fuel pump is inside the tank, which locks into place with a 1/8th turn. You will need a hammer and a brass punch for this job, as it needs to be tapped around to unlock. It will then lift out. Compare the two pump assemblies. The inside parts can be slightly different, but ensure that the fuel lines are IDENTICAL and the wire connection is IDENTICAL. The new one will come with a new silicone seal. Ensure that you don't put the new one in in such a way as the float doesn't bind, otherwise you'll be doing this procedure again if you don't like guessing how much gas you have. This can be a challenge to wrestle with putting the new one in, as you have to push it down to compress the new seal, and turn it to lock it. Once you get it started, you can let up and use the hammer and punch again to tighten it the rest of the way. Next, put it back together just as you took it apart, and don't forget to hook up the wires, hoses, and fuel lines. No tools required for the fuel lines, they just snap together. Once everything's tight and hooked up, put gas back in it, and if you haven't already, put the fuel pump relay back in. This you can do as soon as the car dies, and is completely optional if the car won't run at all. You are now ready to start it up, but turn the ignition on to the run position, wait a few seconds for the pump to pressurize, and then start it. Have fun, and feel free to ask any questions should you have any.

Check your O2 sensors. They will give that affect and work only when your engine heats up. If the car cools down and starts up again, that is a sign that your O2 sensors are shot. Replace them.

I was driving my 2004 chevrolet cavalier it stop run and i can not trun it back on check gas line and no gas is coming up thou fuel line what can be wrong?


It sounds like you have a bad fuel pump, a bad fuse to the fuel system, or the cut-off switch was tripped to the fuel pump. Check you owner's manual to check the cut-off switch reset. If this doesn't fix the problem and you have replaced the fuse to the fuel system then you will most likely have to replace the fuel pump. Start with the easiest solution first before replacing the fuel pump.
