Question about 2003 Chevrolet Impala

1 Answer

2003 Impala starts, runs 2 seconds, stalls

Christmas Eve I had to jump the car. It took almost 20 minutes to get the jump to work, during which time I checked the jumper cable connections several times. Must admit, one of those times I put the jumpers on the wrong posts for about 5 seconds. After that it started and (Christmas miracle) no problems until we were back home except for the radio not coming on (fuse burned). Last Saturday, I was not able to start the car, although the battery and starter feel strong. I hear the fuel pump coming on, too. It will turn over and run a couple of seconds then stall.

SOURCE: 2000 Impala ls car runs fine when first start.

There are NO choke coils on your vehicle, so don't bother looking for something that doesn't exist, just like there is NO carb on your engine. What you have is either a 3.4 or 3.8 liter V-6, sequential multi-port fuel injected engine.

The first thing you should do is replace the fuel filter. This is located underneath your vehicle, in front of the rear suspension. You will need a 10mm socket or wrench to remove the bolt that holds on the mounting bracket for the fuel filter. You will then need to push the fuel line forward towards the filter, while you are pushing in the white plastic retaining clips, then while holding them him, continue to hold the filter with one hand, while pulling back the line with the other, It should easily come off. Repeat for the other line. I recommend this as the first step, because many vehicle owners don't bother to get their fuel filter changed as often as they should. It should be changed at least every 24,000 miles.

Drive the vehicle and see if that took care of the problem. If not, you most likely have a bad fuel pump, which is mounted in the fuel tank, a bad fuel pressure regulator, which is mounted on the fuel rail on the engine, it is usually black with a vacuum line going to the top of it, and you may also have a catalytic converter that is starting to go bad, as once they heat up is usually when the internal grid expands and can begin blocking the exhaust.

This may all seem overwhelming to you, but an easier solution might be for you to take it so a reputable shop and have them run diagnostics on it, with you then bringing home and doing the repair yourself to save on parts and labor. Diagnostic fees could run slightly less than $100, to slightly more than that, but could save you from buying and replacing parts that you don't need.

Hope this helps.

SOURCE: 2003 Impala will start sometimes

it is possible that it's the ignition switch that's faulty, or one of the relays in the ignition circuit

SOURCE: Jump Started, Now More Problems

If you are lucky, it probably burnt a/or some fuses somewhere (probably higher amperage fuses, or a Maxi fuse (large fuse), or it might have burnt a fusible link (which looks like a normal wire and varies on locations depending on vehicles but is designed to melt and prevent current flow in the event of a current overload)

But, you also might have fried some electronic modules...

Reset security code 2003 Chevy impaula

    • 1 Attempt to start the car. If it does not start, or dies very quickly after it started, then leave the key in the ignition in the "ON" position and wait 10 minutes. Make sure the security light is flashing. After 10 minutes the security light will stop flashing and either turn off or stay on steadily. When it does, then turn the ignition off, wait 20 seconds and attempt to restart the car.
    • 2 Repeat this procedure three times in quick succession without removing the key from the ignition.
    • 3 Start the car following the third 10-minute waiting period. The car should start and stay on. If it stays running, then the codes have been relearned and the problem is solved. If the car still does not start then you may need to have all or part of the passlock system replaced

03 chevy impala will not start

I suggest that you take it to a repair ship and have them hook a machine up to the computer in your car to do diagnostics so then you would know what exactly is going on so you could fix it once and for all.

For weeks the car had to be jumped to start, I thought the battery was a problem until one day it stalls in the middle of the road while I was waiting to turn (so I was idling) and wouldn't start up until...

You may check for corrosion on your battery terminals, if corrosion is present then disconnect the cables and clean the corrosion. If thats not the case then just check to make sure that your terminal is connected tightly to the battery post. I recently had this trouble on my brothers spyder and no matter how tight i got the terminal it still would move when i pulled on it so I just went to the parts store and bought a new terminal for $6.99 and had it running again in 10 minutes.

Car stalling out and bot starting after being driven for awhile.

mcdevito75 Here, It"s possible the ignition Module is going bad, no way to test and if so, one day the car will not start at all.----------It can also be a vapor loc, wher the fuel is evaporating before it reaches the cylinders. Best Bet, have your local shop check both these items.

My nissan 350z sometimes stalls after starting

after i replaced the battery in my 2003 350z, it would stall immediatly after i cranked it on unless i gave it a little gas. I fixed this by cleaning the MAF and throtle body valve. Total supply costs were $15 and took about 20 minutes. My Z is not only fixed but runs smoother and cleaner.

2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.
