Three things.
First, you need to check the MAF sensor for contamination.

Second, check fuel pressure, if you dont have a gauge, autozone and Advance have them on their tool loaner program.
Should see 35-40 psi with key on engine off, cycle key a few times, if it takes a while to build up, replace filter and retest.

Third, possible convertor blockage, easiest check is to remove the 02 sensor and try to start with the hole open, if it runs, then that is it, specs allow for 2-3 lbs of back pressure max. That means if you can hear pressure escaping, it is a problem area.

2002 cavalier 2.4 will not start fuel pump runs has spark


FUEL PUMP ONLY HUM'S FOR 2 SECONDS WHEN YOU TURN KEY TO ON, NOT START, POSITION. YOU CANNOT HEAR PUMP RUN WHEN CAR IS RUNNING ! THIS 2 SEC., IS THE PUMP PRIMING ITSELF TO START ENGINE. YOU MIGHT BE HEARING EITHER THE POWER STEERING OR WHATEVER, NOT THE FUEL PUMP!!!!!! GIVEN THE YEAR OF THIS CAR, YOUR FUEL PUMP COULD BE BAD, CHECK FUSES, RELAY, GROUND WIRES, TO PUMP, ALSO CHANGE YOUR FUEL FILTER !!!!! AIR FILTER ALSO !!!!!!! SPARK PLUG WIRES SHOULD ALSO BE REPLACED !!!!

Engine will not start.fuel pump does not run. intermittent problem. has been getting progressively worse. have changed fuel filter. checked electrical connectors.need accurate wiring diagram. chiltons...


start by checking the fuel pump fuse and relay. will the fuel pump run for a few seconds when you turn the key to the run position? If so you may need to replace the crank position sensor. When this goes bad the engine will turn over and start, but only run for a second or two then die like its out of gas.

If you do not hear the fuel pump coming on and the fuse and relay check out good then you will have to see if there is power going to the fuel pump. if power is present at the fuel pump plug then the fuel pump is bad

Where is the fuel pump relay on a 01 cavalier


Assuming you've already changed the fuel filter(and that the filter is facing the correct direction) let's start to think that it IS getting enough fuel and that you could have a possible vacuum leak. First, to close the book on the fuel system, turn your key to the run position a few times. Do not turn the engine over, just turn the key on until you hear a clicking sound under the hood. This is most easily accomplished with the drivers and passengers windows open and the hood open. Each time you turn the key you should hear a click and then about 2 seconds later another click. This, is the fuel pump relay priming the system for starting. If you have someone put their ear to the filler tube(cap off) while you turn the key on and off, they should clearly hear the fuel pump running and stopping.If all that is okay, try to find the small tirevalve type fitting on the fuel rail, the one that runs alongside the injectors. With the key left in the run position, poke the little pin in the center and you should get a pretty good squirt of fluid shooting out from the valve.If you do, start the engine and have your helper listen to the pump in the filler tube again. Run it for a while or whatever time it takes to stall and if he or she heard the pump running when it stalled then your problem is not fuel. Spray some penetrating oil, with the engine running all around the intake manifold, not the air intake at the filter, but at all vacuum lines and around the mounting gaskets for the intake. If you hear the engine start to stumble then keep concentrating the spray until you pinpoint the vacuum leak. I'm tired of typing, seriously...lol Hope you find your problem, thanks, Dana

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.

Please call me its easier to explain on the phone, in the mean time try something easy hit the fuel pump on thebottom with a brick or rock then have someone listen to the fill neck of the tank for the two second "buzz" as soon as you turn on the ignition, has this vehicle been run way way low on fuel many times or the fuel filter neglected to been changed at the 15,000 miles interval?
