99 Malibu won't start

I'd use a digital multimeter leads across battery posts, everything off. The generic spec for a full charge is around 12.6 volts. Leave the leads touching battery posts, have helper turn key to crank, generally the reading shouldn't drop below 9 volts, If it drops way down there, then you need to get the battery charged. Also, check the battery connections. If the reading doesn't drop very far, then check for open circuit to the starter. The reading should drop some. If open circuit, check the ignition switch and neutral switch. Make sure the engine isn't seized by turning the crank by hand. Note the wiring diagram. My info says you have pass lock security system, has no control over starter motor, itself.

when car is hot starter motor is not start 10 or 15 after is coming start
