Maybe it's bad injectors or the computer not telling them to work. Or also a bad ignition module in the distributor would make it not work. You can take it out and have it tested

Your car's engine needs three things, fuel, spark and air. If you have an OBD scanning tool, you can plug it into the OBD port under your dash and test all sensors and components to see if you have any failures. You can also borrow these tools at your local auto parts stores like AutoZone, Orielys, NAPA etc.. Verifying fuel to an injector is not an easy DIY task for everyone.
1) Make sure you don't have an obstruction in the airway (especially a clogged old air filter) from the air inlet all the way to the MAF sensor and into the intake manifold.
2) Make sure you have plenty of fuel in the tank.
3) You could have a relay or fuse that has blown thus not allowing the coils to fire the spark plugs. That would have to be checked also.
What you might think is lack of fuel to the engine could be lack of spark to ignite the fuel. All three (fuel,air,spark) need to be tested.

SOURCE: replace fuel pump on a 2001 chevy cavalier

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.

REMOVAL & INSTALLATION
(see Figures 1 and 2)

CAUTION The fuel injection system remains under pressure, even after the engine has been turned OFF. The fuel system pressure must be relieved before disconnecting any fuel lines. Failure to do so may result in fire and/or personal injury.

  1. Relieve the fuel system pressure using the recommended procedure.
  2. Disconnect the negative battery cable.
  3. Drain the fuel tank, then remove the fuel tank from the vehicle.
  4. While holding the modular fuel sender assembly down, remove the snap-ring from the designated slots located on the retainer.

WARNING The modular fuel sender assembly may spring up from its position. When removing the modular fuel sender from the tank, be aware that the reservoir bucket is full of fuel. It must be tipped slightly during removal to avoid damage to the float.
  1. Remove the external fuel strainer.
  2. Detach the Connector Position Assurance (CPA) piece from the electrical connector and detach the fuel pump electrical connector.
  3. Gently release the tabs on the sides of the fuel sender at the cover assembly. Begin by squeezing the sides of the reservoir and releasing the tab opposite the fuel level sensor. Move clockwise to release the second and third tabs in the same manner.
  4. Lift the cover assembly out far enough to detach the fuel pump electrical connection.
  5. Rotate the fuel pump baffle counterclockwise and remove the baffle and pump assembly from the retainer.
  6. Slide the fuel pump outlet out of slot, then remove the fuel pump outlet seal.

To install:
  1. Install the fuel pump outlet seal, then slide the fuel pump outlet in the slots of reservoir cover.
  2. Install the fuel pump and baffle assembly onto the reservoir retainer and rotate clockwise until seated.
  3. Install the lower retainer assembly partially into the reservoir. Line up all 3 sleeve tabs. Press the retainer onto the reservoir making sure all 3 tabs are firmly seated.

Gently pull on the fuel pump reservoir from retainer to assure a secure fastening. If not secure, replace the entire fuel sender.
  1. Attach the fuel pump connector.
  2. Fasten the CPA connector to the fuel sender cover.
  3. Install a new external fuel strainer.
  4. Install the modular fuel sender.
  5. Install the fuel tank in the vehicle.
  6. Connect the negative battery cable.
  7. Pressurize the fuel system and verify no leaks.

Its possible that you have ruined the fuel pump by running it low on gas. Since the fuel pump is cooled by the fuel in the tank it is important not to run them empty.

There are a few things you can do
1. Listen for the sound of the fuel pump running when you turn the key on. It should run for 3-5 seconds.
2. Check for fuel pressure with a fuel pressure gauge.
3. check for spark.
4. Always post an engine size when asking for automotive advice. This will help give better, more clear directions and what, where, and how to do the above mentioned.

If you can't here the fuel pump running or there is no fuel pressure than your pump is likely bad. A new pump and fuel filter should have you back up and running.

If you here the pump or you have fuel pressure and you don't have any spark than there are several things that can cause this. I can run through those with you once you know whether or not you have spark.

If you're missing fuel or spark or both let me know and I will help you further.

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

2001 Chevy Cavalier won't start


It wont ignite is what you are saying! this could be a few things, I will need more information than this but will give you a few possibilities in the mean time. First, are you getting fuel? prime the intake(spray some WD40 into the intake (through what looks like the carb. but is actually a throttle body) if it ignites check fuel pump pressure and filter. Next is ignition, you could have several things going on here from cam or crank pos. sensor to coils. do you have a OBDII check engine light on, on the dash. This will reveal a code to help us decide what the problem is.Let me know.
Good Luck,

2001 cavalier died while driving, now it wont start


Could be failed fuel pump. Disconnect fuel line at engine and turn over a couple times having something to catch gas in. If electric pump don't turn over engine, just turn key to run position for a few seconds. Maybe clogged fuel filter or faulty pump if no gas shows. Change fuel filter and try again. If none, change pump.

2003 Chevy Cavalier not starting


When you turn the key, you should hear the fuel pump make a whiring noise as it dispenses the fuel. If there is no noise. the fuel pump is not working.

Have you checked the fuel shutoff inertia switch.?
Check your owners manual for location.
