Chevrolet Malibu Start Up/Ignition



  • 04cad04cad Posts: 131
    Are these the new body style Malibu's or the "Classic" Malibu body styles? In 2004 and 2005 GM made the "Classics" and the new body styles. It may help to figure this out if we knew which ones for sure?

    I have a 2005 malibu LS 3.5 liter engine and i have had similar problems with the starter still cranking after the engine has started and the key has been released from the start position. There is a service bulletin (hot start) starter not disengaging after starting ,had the computer re flashed with updated software upgrade and solved the problem. Now eighteen months it occassionaly does the hot start and does fire the engine but not like when it was new.

    From 2004 and on there is a Classic and Malibu Z body. When I read a Malibu post 04 or newer I never know if it is Classic or Z body. Not everyone knows the difference.

    Chevy made the Classic in 2004 and 2005 as a fleet car. The new body style was also made starting in 2004.

    There was also a Malibu classic in the 70's as well as a Silverado classic in the 90's.

    It is used often to use up the old body style parts even though a newer body style has been introduced.
  • I own an 05 malibu classic, it has about 90,000 miles, I have delt with many problems with this car like the anti theft lock, wich i was willing to cope with. about 2 weeks ago I tried to turn on the car and everything shut off there was no electric current as if the battery had died. After a while it would re-set but every time i tried to turn it on, the same thing would happen. I read in a forum that this had happened to someone else and they put the car in nuetral, and cranked it. So I tried this and it worked. It was working fine but now sometimes it will do the same when in neautral has anyone had this problem.
  • We have a 2004 Chevy Malibu LT. For some reason, randomly the car does not start. We are wondering if its the battery but I doubt this since the car starts on other occasions. Also when the car doesn't start, the radio, turn signals and dash all light up and work.

    The only way to start to car is to give it a boost. Besides the battery needing to be replaced has anyone else heard or experienced this problem before? We are also suddenly having problems with the remote starter. When we try to remote start, the light just flashes and the starter gives up.

  • Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.
    No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
    EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.Broken spring(accumulator)
    Just some things to look at !
  • We are having a problem with our horn. When we honk, the noise is not clear, it almost sounds as if the horn is worn out. Anyone know if this can be replaced?
  • disconnected battery on a 98 malibu 3.1, when battery reconnected the gas gauge will not return to show amount of fuel ,it is on the opposite side of the pin that arm rest on ,tried disconnecting battery again, but gauge wont reset help
  • Yes, I had the same issue, I had to have the key ignition replace. The key was not making contact, and this would cause my anti-system to shut down. Once I have the Ignition replace the problem stop.

    The problem that I am experiencing now is with my car is not getting gas. I've had the fuel pump replace three times, and I am still experiencing the same issue. Hope you can advise.
  • My car just did this same exact thing to me...except its not starting at all now. Calling the dealership to come get it and check it out. I know its time for a tune up but to stop starting all together...just hoping its not too expensive this go around. I will post again once I know the outcome.
  • For those of you who have a 1997 - 2003 Malibu and have been having problems with the Security system keeping you from starting the car, read on....

    I am a retired GM Electrical Engineer. I own a 2002 Grand Am, and had this problem two years ago. I bought a Shop Manual for my car ($130.00), and worked out a way of bypassing the Passlock II system on my vehicle. After making the modification on my car, I have not had a single instance of No start caused by the Security system.

    Last week, as a favor to a friend, I performed the same modification on a 2003 Alero. It took less than an hour. (not counting the time I spent taking photos of my progress) The modification was successful on that vehicle.

    Details of the modification are posted on my personal website at:

    There are instructions on how to do the modification using two methods. Both methods bypass the security module in the ignition circuit. One bypasses it at the connector to the Body Control Module, which is under the glove box. The other does the bypass near the ignition switch, which can be reached by removing the radio.

    The Malibu, Grand Am, and Alero all used the same security system in certain models, and the bypass method works for all of them. Please post back if you find the instructions useful.

    I have 2005 and 2006 Malibus, and have no such problem, but I did take a look at your site... Wow, what a treasure!... I've got to explore the stuff there, later -- seems very instructive no matter what model I have...

    Thank you for sharing your experience in such a thorough way!

    Thanks for the compliment. I doubt if the instructions on my site will help you, as your vehicles have (I think) a newer system, which uses a key with an embedded chip, and is considerably more reliable than the Passlock II system. (My 2007 Cobolt has the new system). You can tell because the keys with the embedded chip have a "+" stamped on them right below the plastic handle. There is, however a way to keep from spending $35.00 per key for replacement keys. When you lose one of your keys, take the other one and go to a hardware store and have two common duplicates made, at $1.50 each. Then take your remaining key with the chip in it, open up the shroud that is around your ignition switch, and tape the transponder key inside the shroud. You will then be able to use ordinary keys to operate your car. The key with the embedded chip needs only to be close enough to the ignition switch so the vehicle can receive it's signal.

  • Hi

    I know you posted this a while ago. I have the exact same car and the exact same issues and every time i take it in the car won't do anything so I look like im making it up. Did you ever figure out what was wrong with it?
  • I have a 04 Malibu LT with 74000 miles on it. I have had problems with it not wanting to start unless I give it gas. It does not happen all the time and I tak it in and they find nothing. I have ad problems with the remote start not working and the curise will not work all the time and of course it works when I take it in. Any Ideas I need Help asap as my warranty is up friday and the dealer says they don't know what is wrong with it
  • hi,
    my problem was that my car's battery got discharge problem some time once a month. i just check the pattern and found that there i used to remove my car keys when my transimmission stick is on Drive "D" (i.e my ignition switch) was faulty.
  • Yeah...the starting problem was COMPLETELY the battery.

    I had the battery checked before, and the meter showed it didn't need to be replaced...but someone at the GM dealership recommended the battery change...instead of paying through the nose for diagnosis, I went with an independent mechanic and replaced the battery (it was 5 years old.)

    That did the trick. No problems starting since.

    Hey everyone i could really use some help ive been trying to fix my sisters car and im stumped. we bought the car with a 3.4l in it from a chevy venture, it had overheating problems and suspected head gasket failure w/ no oil coolant mix. I have replace the following; head gaskets, head bolts, heads were resurfaced and a shim was added with head gaskets, upper and lower intake gaskets, throttle body gaskets, injector o-rings, spark plugs, plug wires, oil change and filter, thermostat, cooling system flush, power steering pump, air filter, fuel filter, and fuel pump along with some other things like tires and rotors and brakes but those wouldnt cause the problems. after all that work was done and the car was reassembled it will just crank all day but wont start, there is no fuel pressure but there is spark and proper compression. the relay under the hood clicks but neither the old pump or the new one makes any noise and the there is no power at the connection. i was looking around and came across all of the complaints about the passcode theft system and it deactivating the pump and injectors. my theft light is on and it stays on and does not blink. i have tried the ten minute reset thing and i tried the resistor bypass thing, and the car still only cranks and will not start. anybody have any help at all they can offer ill answer any other questions you might have. thank you for any help,

    Only one post for same problem please, avoids confusion.
  • hi, I have a chevrolet malibu classic 2004,and i did the bypass thing to it and it didnt work,the car start in the cold morning but after driving the car for around 20 min it wont start,i place the key in on position and the check engine light is on and i can hear the fuel pump working and the car can start,but if i place the key in on position and the check engine light dont come on then the fuel pump doesnt work and the car wont start,i replace the fuel pump relay and still having the problem,i took out the relay and i place a tester in one of the slots and then i putted the key to on position and the tester light was weak and the check engine light off and when the check engine light is on the tester light is stronger,looks like the relay is receiving low volts from somewhere
    plz HEEEEELP
  • Sounds like you have a short, they are very hard to catch in the act. Keep at it.
  • gonogogonogo Posts: 879
    Maybe ignition switch, the electrical one not key. Should be mounted on back of key switch assy.

    I am having the exact same problem, my mechanic or dealer can't find out what the problem is. Seems like outside temp is effecting what is happening. Same exact problem with check engine light, hearing fuel pump, etc. Where you able t find what the problem was, cost, any info will help. Thank you!!!!
  • gmcustsvcgmcustsvc Posts: 4,252

    Were you planning on taking the vehicle to the dealership to be looked at? Please keep me posted when the issue has been taken care of.

    Thank you,

    Thanks for you reply! I already took it to the dealership and they had no clue after diagnostics. They just wanted to change the fuel pump to see if thats what it was, $700 for the pump alone! Also my reg mechanic of 11years diagnosed it as well. outside hot temp seems to have a definate effect. What do you suggest? Thank you!
  • bullred00bullred00 Posts: 4
    Caron, just got to my car after the heat of the day and the check engine light came on when I turned the key to on, heard the fuel pump come on and she cranked up right away! The problem started back in April when the temps started to get hot here in Pensacola, FL. Also when the check engine light does not come on, the fuel pump relay makes buzzing sound, changed that out.
  • gmcustsvcgmcustsvc Posts: 4,252

    I would recommend having the dealership involved Technical Assistance. I would also like to set up a case with GM Customer Assistance. In order to start the process I will need your complete contact information (including full name, mailing address and phone number), VIN, current mileage and the involved dealership sent to me in an email. Also, could you please provide a brief description of the problems you are experiencing?

    Thank you,
    Caron, GM Customer Service
