Problem with my 2005 Chevy Malibu
4 cyl
Repairs = replaced starter and battery.
tech JK
question = car will not start when outside temp is cold. After it
warms up it will start and run great. Key turns, lights work and all but
car will not turn over. Why does my car not start.

The security system on todays cars and trucks prevents the vehicle from being stolen. There are many variations of the
system going back to the early 1990's.
This warning could be on when the engine is running, indicating a fault has been detected in the system. If left
unrepaired, there is a good possiblity that the car will eventually not start.
There are several different possibilities for the cause of the warning, depending on the make / model / year of the
vehicle. Anything from a bad ignition cylinder wire, to a bad cylinder to a dad Body Control Module (BCM)
system going back to the early 1990's.

Really need to know if this is the Malibu new body, or Malibu classic.
On the new body style Malibu, there is a computer(PCM) re-programming
available to correct an intermittent no crank condition.
On either body style, checking that the battery cable are clean and tight is
the first step. Next, see if the theft / security light is on after trying to start and
it wont. That would indicate a security problem. Other areas of concern are
the ignition switch or starter relay.

GM Tech JK:
If you are sure the fuel pressure is fine when it stalls, then you may have carbon build-up in the
throttle body, plate and bore. A possible vacuum leak. Or possibly carbon build-up on the Idle Air
Control Motor (IAC), or the IAC is faulty. This is what controls idle speed.
Have it inspected for a vacuum leak.
Remove the IAC valve and clean it. When cleaning, do not move the plunger at all, just clean it,
and the bore it sits in.
Remove the air intake tube between the air filter and the engine to clean out the throttle body,
bore, and plate. Then take it for a drive to sort of "Blow it out". Doing a few hard accelerations.
