Check the cables for correct tension. If the cables are too loose on the battery, the condition you describe can occur. Also, the battery cables can be fine, and the battery appear to have enough voltage, but can actually have a shorted cell which breaks down under starter load.
Check for corrosion on battery terminals (a white, crusty substance which feel slightly crunchy and greasy between the fingers); this corrosion can be harder to see on side-post battery terminals. Corrosion almost always happens as a result of too loose cables and alternator overcharging. Overcharging is as bad for a battery as undercharging.

Good luck.

SOURCE: When car sits for 3-4 days, battery goes down.

You either have a battery that is giving out on you or something is draining the battery when it stands for a while. Have the battery tested first . If that checks out ok then you will have to check for the electrical leakage in your system.

2002 ford windstar first wouldnt start, jumped and started, drove 200 miles and turn

You need to have the factory security system scanned, it is most likely locking you out due to a fault.

No start turn the key and nothing

Does the car crank? If not, does you lights dim when trying to start? If your lights are bright and the car is not starting than It's most likely the starter. If your lights are dim than try to jump start it. If it cranks and still not starting than it could be so many different things.

1997 Jeep Grand Cherokee Laredo Sometimes when you hit the key it seems like the electrical system is dead. After letting it sit for awhile it will start and sometimes will die at idle.

GOOD LUCK

1999 oldsmobile silhouette wont start by igition but self started

The radio and lights usually work when the battery is mostly dead. Check battery and cables to make sure you have a FULL contact. Also do the same with cables and starter. Most parts stores will check battery, altenator, and starter on bench test or in the vehicle for free or extremely cheap. Also you may want to check starter relay for current with an ohmmeter

you meant its a NO CRANK engine.
silent starter, say the word silent.
even the starter relay must click.
and if head lamps die, so will be the starter.
due to a dead battery,
sounds like a bad battery to me. dead or only
if the Charge/battery lamp is off in the cluster driving. its ok. the alternator.

starter car with the jumper cables connected
and not next day.
only live jumps matter. or you go know where.
if you want to walmart they have tool there that
tests the alternator
and for phantom drains all in 6 min work, the tool does all the work.

if the battery is charged, it will crank I bet
its discharging.
for 1 of 3 reasons.
1: its bad.
2: the charge system is dead.
3: phantom drains, it goes dead as you sleep
the head lamps dead is the big clue there.
