I was driving home doing about 60 mph and came up to a red light. When I I stopped at the red light there was no problem light turned green and pulled away next thing I know the engine started to chug. I was thinking that I ran out of gas but it didn't die just total loss of power. Well I kept it going for about another 1\4 mile and hit a hill it wouldn't even pull the hill.so I pull over and it is just idling but with a rilly bad chugging so to try and save the engine I turn it off then about 10 second's layer I start it agien. Still chugging and it won't stop so I turn it off agien well that's the end of the car. It will start but dies immediately. And now there is this weird humming sound back by the gas tank that wasn't there before the car did this. I'm thinking fuel pump but hopefully it is just a clogged fuel filter. But the end of that trip to the store ended with the car getting towed home and the pack of cigarettes I bought may end up costing me way more money than I ever thought about spending.
Won't start, pumping not turning on. Replaced relay, still nothing. Sprayed starter fluid in carberator and started.
Replaced fuel pump n still have the same problem
I drove my car home from work cut off the engine. Went back out to leave again and the car would not start. the radio and lights did come on but after awhile the total car was dead. I was told this could be the fuel pump in this type of car.
I have a 05 chevy impala its high in miles but still manages to run great.. However for the last past week i noticed my car not starting up right away like it normally would.. When i turn the key to the on position everything comes on like it should lights..security light.. Battery light.. Etc..but my car struggles to turn over and once it seems like it gonna turn on it shuts off..i have to press on the gas pedal a couple times for my car to fully start and stay on..once it on it stays on without stall...yet!! However i do feel when im drive it like its has short soft pauses or loss of power for a quick second then will stop.. But now its happening more more while im driving and sometimes lasts until i get to my destination. When starting it again after while driving it sometimes it will start as it should with no problems other times i have to press the gas pedal to fully start it again. I have taken it to few mechanics .. But no one can give me a sure answer to what it is.. But every one of them is leaning toward the fuel pump.. My check engine light is not on.. So they cant run a diagnostic on my car.. So im in the dark as to what i should do.. Fuel pumps are not cheap.. So i dont want to pay for a fuel pump if its not the sure problem with my car.. But i need my car..so i have to do something regardless and soon.. Can anyone help me and give me their opinion on if its the fuel pump or something else.. Thanks

hard to start.chugging before start and loss of power.
car will not always start,. acts like a dead battery try again it starts diagnosed problem to be long memory processor,or EMC and am told this is a recall item.Car is a 2012 Cevy Impala. Vin number2G1WB5E35C1187502
Is this a recall or not ? If not what is the fix?
My 2010 Chevy Impala V6 3.5 L Flex Fuel is having issues. Drove great for years, since we got it in 2010 and now that we went on vacation and let it sit there for 4 days it will not start. All electronics work in the car but the fuel pump will not connect and we can not find a correct replacement fuel pump even if it comes from the same model and year of car. Since there are so many people having the same issue with the same car I am wondering why GM has not issued a recall on the cars.
My vehicle stalls out while I'm driving even on the highway. At times it won't start and when it does it sounds like it has a misfire. If I wait a few minutes and restart the vehicle it starts up without any problem. I was told that I need a fuel pump which is very expensive. I've had so many issues with this vehicle so I'm not sure if I'll have it replaced or not.
Car is turning over but won't stay running, tried to pump gas when starting, car is sputtering and dying out and sometimes sounds as if its backfiring. I was told it could be the fuel pump so i'm about to change that and see what happens. If any other suggestions please feel free to let me know.
Same as yall but when cut off after about 2 hours is started back up agin. I drove less than a mile to the store and came back out now it won't start agin...
Runs fine for about 1/2 mile then chugs and won't accelerate easily
I WAS TOLD IT WAS CATALITIC CONVERTER,BUT WE THINK ITS IGNITION OR FUEL INJECTORS
my fuel. point failed also and it cost 600$ to get it fixed.
paid for a diagnoisis, they said it was the fuel sensor...so had that replaced, dealer called and said car still wasn't right and now they said it needed a new fuel pump as it had a hairline fracture and a seal was melted....hmmmm.
So ofcourse, added about another $600 to the bill.....still don't have my car back....it isn't fixed yet.....I don't know what to expect next or where to go with this. It is at a reputible Chev dealership....help!!
I was driving hearing a knock on my way to get locus AND my car jerk AND stop working mechanic AND the mechanic said its no fuel come out even when he open it AND was telling me to turn the key but don't try to start it the he will tell me to try to start it no success
Turns over slow when gas tank gets 3/4 tank empty but runs good until then
Just happened to my mom who just purchased only a year ago Chevy says it was not a recall issue car. And that it would be $800 to fix. But not covered as it was covered only for 36,000 miles. Really upset not ever going to buy a Chevy looks like lots of cheap parts and recalls all the time.
The car will run for 3 seconds and turned itself off and will not start again for hours and when it does start it does the exact same thing still have not found a fix need help
Car stalls and have to wait 15 to 20 mins and or keep trying until it starts
