2005 Buick Terraza Q&A

2005 Buick Terraza Question: why my 2005 buick Terraza will not stay crank?

The horn will blow and the lights will come on but when I crank it up it cuts off. -
Answer 1
Have the battery tested. Horn and lights require only a little power to operate, the starter draws much more and maybe the battery can't handle the load. You might try jump starting the car. -
Answer 2
Is your security light staying on? -
Comment 1
No the security light is not on ,however the car will not start on a boost either. All the lights are on it turns over but will not stay. -
Comment 2
The boost is mis-leading, it tells us the battery does not have enough amps to spin the starter. Is there any codes associated with the no start condition? -
