SOURCE: 03 impala turns on and

Is there a check engine light on or trouble codes stored in the PCM? (powertrain control module)
How many miles are on this vehicle? The first step is to check the PCM, but you will need a code reader to do so, or bring the vehicle to an Autozone or similar store, and they can check codes...free. I'm not sure what the diagnostic result was for CKP replacement, I'm assuming there was a code(s)????

Sounds like your battery is flat. Put the headlights on and turn the key. Do they go dim like a glowworm?

Caliber will start for a second then die. when i try to start again it will not crank. i have all lights and power in the car seems normal. ill let the car sit for a few hours and it starts fine.


Well if the vehicle starts even for a few seconds .That means you are getting fuel and electrictal supply to give you a spark through the coils wires and disturbuter at least start up .
Then you say you let it sit a few hr's and it starts again
Why did you have to put a new battery in it If it starts fine .
You have a problem with your fuel system not delivering enough fuel .
You can pretty much rule out the electrical system the battery turns the starting motor .
The vehicle it 08 not really old enough for a fuel pump to go but fuel filters clog and that will damage the pump aswell and cause a condution similiar to what you have described and while your at it take out the air filter that will help to .
Give this a try follow the fuel lines from the pump to the engine you will see a fuel filter change it .The vehicle will likely run again
For 10 to 20 dollars out of pocket

That symbol means low voltage in the system, you have a dead or defective battery. These new sealed batteries can go out of the blue, starts fine and then a few minutes or hours later nothing, no crank no start. You can confirm the battery is the problem by honking the horn, it will dribble out a noise or not work at all if the battery is dead or nearly dead.

When the key is held in the start position for .4 seconds. The pcm/ecm has a start timer, it will crank until timer is timed out even though you release the key. That is normal. I don't know how long the timer runs?

As far as vehicle starting, check the basics. If it cranks good but won't start, have a helper crank it while you check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Any applicable trouble codes? I can only help with testing.
