Make sure it is in park. Clutch pushed in. Dead battery.
see if it will turn over if there is no grinding noise then u need a new starter
Does the engine turn over and then make the clicking noise while trying to start, or does it not do anything but make the clicking noise when you turn the key. If its not turning over at all then it might be a battery problem, Try cleaning the battery terminals, and/or charge the battery, Could also be the starter solenoid, but start with the battery first.
if it does not turn over and no clicking noise but headlights on, check start fuse and relay if it doesnt turn over and clicks probable starter solenoid
dead battery
When you say it won't start, are you referring to the grand am won't turn over as in it's dead or are you asking what's wrong when it does turn over but won't start?
battery. key circuit, or solenoid.
what is wrong when the truck just turn over and want start.
If your car doesn't start, or when you turn the key it makes a weird noise. Lights dim, slow to turn over,
Check your timing belt , and your fuel pump inertia switch ! Good Luck !
Turn over a new leaf. Start over. Make a fresh start.
You may have gotten the valve timing wrong. If a valve is open when the piston is at TDC it may hit it, doing considerable damage.
my first thought would be to check the starter . if you can tap on the starter and it starts after that..you have a bad starter .
