Why will a car not turn over if there is power and the starter and alternator are new?

Internal combustion engines need 3 things to start and run: air, fuel, and spark. First look over all of your fuses, to make sure none of them such as the fuel pump fuse, or the fusable link have burned out. Make sure your battery is not faulty, even a brand new battery could potentially be no good. Check the voltage with your volt or multi meter, it should read around 12.5v. Inspect the cables to and from the battery and alternator, but sure they are properly installed. Check your air induction system, make sure the air filter is nice and clean, no blockages. If your vehicle is equipped with a MAF (Mass Air Flow Sensor) make sure it is plugged in correctly. Likewise if your vehicle is equipped with a MAP (manifold absolute pressure sensor) be sure that is plugged in correctly. Visually inspect the entire length of the intake piping, for loose clamps, cracked piping, or gaps. Once you have completed that if your vehicle has a distributor system, remove the distributor cap and replace it if necessary. If you see any visible damage to the spark plug wires, or the age of them is unknown replace them. Next check your spak plugs for the correct gap as recommended by the manufacturer, be sure they are in good shape before reinstalling them. If the vehicle still will not start, try replacing your fuel filter. This is usually inline, though in some cases it is in the fuel tank itself. Once that is completed turn the key to the accessory position, in most vehicles you should hear the fuel pump turn on and prime the lines for starting. If you do, you should be in good shape at this point.

What is a high-torque starter?
It has a whole lot more power then a reguler stock starter does. It will turn the engine over faster.
When you turn the key to start the dash lights go out and engine does not turn over and the solenoid does not click with a good battery.?
The battery power is not reaching the starter. You have other problems...
1997 Astro van will not turn over but has adequate power everywhere in cab Tried jumping it but still no luck. Starter motor will not move. IGN relay in fuse bay clicks when I turn the key.Help?
if the battery has enough power, it could be the starter itself, poss a bad spot on the motor, could be a bad connection at the starter or positive battery cable, maybe corrosion on the terminals.
What could cause your motor not to turn over if you have a new battery and new starter?
Could be the starter relay
Your car wont start but has fuel and battery power What is wrong with it?
It could be a lot of things. Does it turn over? If not it could be a low battery, contacts that are corroded or not tight enough, or you're not in park or neutral. If it does, it could be flooded (especially if it's carbureted) making it smell a lot like gas, or there could be humidity in the distributor. There are lots of other reasons, but in my experience these are the most common.
What cause alternator not to produce power to start engine?
The alternator produces power to charge the battery. The battery powers the starter to turn the engine over.
You have a 1986 Chevy cavalier you have power to everything but the car will not turn over and the starter and the alternator are new so what should I check?
I would check the power right at the starter. Either the solenoid on the starter is defective or the connections/ battery are poor.
What would make your 96 gmc jimmy not turn over with a good starter and alternator?
a defective starter switch
1987 Chevy blazer wont turn over after replacing starter?
did you check your battery and alternator?
How do you tell if you need a new starter or ignition?
If it's the ignition your vehicles motor will not turn over at all. If it does turn over it's either one of three things: battery, alternator, or starter. You can take your starter, battery and alternator to a local advance auto parts and they will test the charge for you. That will tell you what you need to know.
Nissan Sentra does not turn on battery is charge?
If it won't turn over then suspect the starter. Check for power at the starter itself.
Why would a 1997 Nissan Sentra turn over with no key after you change the alternator?
wires from the starter to the harness are touching
If the engine doesn't turn over on a 91 olds cutlass calais how do you know if it is a starter of alternator problem?
AnswerIf the battery's dead it could be the alternator or a bad battery. If not, the starter. Try jumping it. If it starts the starter's OK. Then investigate the alternator and battery.Does it turn over but not start..?? There is a difference. Doesn't turn over would most likely be the battery, which is typically followed by a clicking noise. That would be the starter solenoid trying to engage but the battery doesn't have enough power to do so.If jumping it starts it right up, let it run for 10 or 15 minutes then (while running) check the voltage at the battery terminals. If it's above 14 volts, the alternator is doing it's job and the battery is dead. If the voltage is less than 14, then the alternator needs to be replaced.
Why do I turn the key and starter won't turn?
I have a 1997 grand am and i have power to the starter but when i turn the key over it wont in gauge the starter. all fuses are good. You may have a defective ignition switch.
How do you know if your alternator is not working?
Car won't start... engine can turn over, no power.
If my 1964 ford engine wont turn over after i change my starter solenoid and battery what could it be?
Check power from your ignition, and power at the starter
Why won't a car start without it's batteries?
The starter needs power to crank the engine to get it running. Once the engine is running however, the alternator generates enough power to keep it running. But with no reserved power (a battery) the car cannot turn over.
