SOURCE: how to replace water pump on 2.4 chevy cavalier

This is a job for the dealer or cerified mechanic. The front cover and timing chain needs to be remove to access the water pump mounted behind the engine. The pump is driven by the timing chain and timing will need to be reset using special tools.

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.

I have changed the fuel pump twice on a 1998 Chevy Cavalier 2.2 Liter. I have also changed the fuel filter and the relay switch. The fuel pump wont kick on when I turn the key on.


The original Chevy pump motor has a good life. Running the vehicle out of fuel, which will actually run the pump in a dry state can shorten the expected life span considerably. Gasoline is a petroleum product and actually lubricates the inside of the fuel pump. The more you run the vehicle low on fuel or out of fuel, the more damage will occur and the quicker the pump will fail. Try replacing the pump and follow the above procedures for a good performance of the pumps. Cavalier fuel pumps available here

2003 chevy cavalier fuel pump will not kick on and the fuel pump is fine did replace the relay switch and still want start.


how do you know the fuel pump is fine. did you check for voltage at the pump. When you cycle the key you should have a reading for 3 seconds, then it should drop to zero. You only get a steady voltage if the engine is running. If you spary quick start or brake cleaner in the throttle body and it starts you will need check the above suggestion.. If you have a 3 second pulse then the pump failed

My 2004 chevy cavalier runs when I spray starting fluid into breather. Any suggestions on where to begin troubleshooting?


fuel pressure is your problem here. dirty or restricted fuel filter may be causing your problem or you may have a tired fuel pump. (if it stays running) if it dies you may have a bad pump. you can never go wrong with replacing the filter first. it is recomended maintenace.

My 2003 Chevy cavalier was running fine this morning and now it wont start. I am thinking the fuel pump has went out on it but I have pulled the relay from the AC and swithed them around but still nothing....


With a test light probe...Check for voltage signal at the fuel tank harness connector unplugged and probing the connector cavity.Key ON/no start cycle will power the pink/blackwire for 3 seconds (10 secs apart) each attempt. If the test probe illuminates each key cycle,it gives you an accurate diagnostic for your symptom and you can proceed with fuel pump replacement knowing it is the failed part.

03 cavalier w/ no fuel at fuelrail or in lines (fuel pump)


Could be a fuel pump relay or fuse. These are both located in the engine compartment fuse box. I would check these both out. If one of those isnt the culprit I will help you push it off the cliff. Thanks for using fixya!
