I assume the fuel pump fuse is good?
The only time voltage will be sent to the fuel pump will be the first 2 to 3 seconds if the starter is not engaged. You will want to crank the engine over and check for voltage on the load side of the relay, circuit #30 at the relay.
Let me know after you check.
Regards,

are you using the original key ?? sounds wear but in the key switch there is a sensor that detects if the right key is in use otherwise it will kill the power to the fuel pump or it can be a fuse look under the left rear passanger seat there is another set of fuses and the other set of fuses are on the driver side near the door and there is another set of fuses and relays inside the hook next to the battery

1st ensure the fuses are all good and there is fuel in the vehicle and your not getting a false reading by tapping on the tank ..does it sound Hollow oe Empty / another way is turn on the key and listen for the pump to work a slight humming should be heard ...if so locate the fuel bar and cap screw depress the valve shielding your eyes with say a towell and see if gas dispurses make sure the key is on while doing this if no gas is there or fuel pump is heard then it may be either a bad ground to the unit or the fuel pump itself corroded connections will contribute to this as well unclipping and reclipping the connection togeather should allow a better connection

Why cavalier 2000 almost starts but won't what is the problem, battery and starter ruled out


That should be enough gas. Maybe the fuel pump is not working. Turn the key to on- you should hear the buzz or whine of the pump iin the gas tank for about 2 seconds. It should turn on briefly to pressurize the fuel line and then shut off until the car is cranked over. If you don't hear anything from the rear when turning the key to on, the pump may have quit working or power is not getting to it. Occasionally, a pump will still work but not well enough to make sufficient pressure for the fuel injectors to work. To check that, the pressure would have to be tested.
So, listen for the pump. If good, check your ignition by checking for spark at a sparkplug. If no spark, the ignition system will have to be checked and tests run to find the problem. If you have spark and still no go, test the fuel pressure. If pressure is low, replace the fuel filter and re-test.

Chevy 2001 Cavalier won't start


Trace the power source from fuse to relay etc and make sure pump is working. if all checks out then check pump working and for preasue at engine. you may have a dammaged fuel line from the tank which would also cause the same problem

Wont start after running out of gas


Your fuel pump, fuel lines, and (or) fuel filter may be clogged from drawing sediment/impurities in the bottom of the gas tank. You should begin with replacing the fuel filter (because its cheap and easy to do). If it still does not start then you should check the fuel pump and gas tank.

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.

Ran out of fuel


The reason is: When you completely run out of gas your gas lines are completely drained of fuel. When you refuel the car the fuel lines are still empty, and you will need to crank the car until the fuel pump has filled the gas lines and established the correct fuel pressure.I also suggest you turn key to on position to let electrical system run fuel pump and when ready to crank over engine have battery hooked up to a battery charger this should do it!!

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.

Fuel pump or something else


Hi the trac off light and the car not running have nothing to do with each other
the TRAC OFF LIGHT will set a code in the EBCM
to check the fuel pump remove the gas cap and have someone turn the key to run and while you listen at the filler neck if you can hear a humming noise then the pump is working
if the pump is working then check fuel pressure and spark
hopes this helps you
