There is no ignition when key is fully inserted and turned to on position. The battery and alternator are in very good shape. It looks like I need a new ignition. Might I need a starter too, or is that a separate problem?

How did you come to the conclusion that you need a new ignition? I assume you mean you need a new ignition switch and not a complete ignition system including coil, distributor, etc. Do a quick test. When you turn the key to the run position, several lights on your display will come on. If you turn further to the start position, those lights should go off, and the starter motor should spin. If you have lights in the run position and the lights go off in the start position, your ignition switch is ok. The problem becomes the starter activation circuit.

Next, check that the start fuse is not blown. Also, ensure the fusible link is not burnt.

Finally, to test the starter, either remove it from the car and take it to your local auto parts store for testing, or get an assistant to help you. To test the starter in the car, get a voltmeter or test light. Attach the negative lead to the car ground. Verify that you have voltage on the starter terminal (the one with the big wire). If yes, place the positive lead on the solenoid terminal. Have your assistant turn the key to the start position. Your test light should illuminate or you should read 12V on your meter. If so, replace the starter. If not, find out where the wire is broken so you are not getting voltage to the solenoid.

My Ford KA has no power on the ignition switch. Did check all the fuses. No problem there. Don't know where else to look. Help please

The most likely reason for ignition power issues is either a flat battery or a fault in the charging system. Do you get dashboard lights when you turn the key to the first and second positions? Do the dash lights dim when you turn the key to position three, (Engine start)? Do you get any sounds when you turn the key like a 'click' or the engine turning slowly?
Here is a simple battery test. Turn the ignition to position 2, (ignition On, engine Off), Turn on your lights and switch to Main/High beam. Stand in front of the car an look at the front lights. If the battery is low they won't be very bright.
Do you have a multimeter? Put the probes directly on the battery terminals with red to the positive and black to the negative. The multimeter set to volts should give you a reading of 12.6 volts or higher for a fully charged battery. Anything at or below 9 volts will not be enough to start the vehicle.
** Keep well clear of any moving engine part!**
If you can get the vehicle started, (Jump leads or 'bump start'), use the same method on the battery. This shows if the alternator is supplying charge to the battery. You should get a higher reading, somewhere around 14 volts.

2006 Ford taurus won't start, starter, altlernator, battery replaced, ignition starter switch, neutral safely switch changed, still nothing

I looked at info for your security system, it is starter motor disable. I didn't see 06 ford Taurus in my database, so I looked at 05.
Battery has a full charge and battery connections all good?
We can usually do some tests to see if starter motor will crank the engine, but, if the security is the problem, it still won't start.
You can check for applicable trouble codes? Try a different key?

95 Pontiac Grand Am GT V6 just died wont start? starter is good, dont know if alternator or what?

If the engine will not crank, and the battery is fully charged, the only thing in play is the starter circuit. The ignition and alternator do not get involved until after the engine is started.
If the engine died and will not crank, you would need to check for voltage at the starter with the key switch in the start position.
You may need a manual with wiring diagrams to trace the circuits.

Starter relay clicking, but car wont start

Locate your starter and with the vehicle in park have an assistant hold the key in the crank position while with a test light you check for power at the posts on the starter solenoid. One post shoul have power from the battery, the other from the ignition switch and the other should supply power to the starter motor. Make sure your battery is in good shape and fully charged. If all you get is a click from the solenoid then it's likely that you need a starter. If no power fom battery check battery and positive cable/connection for integrity and tightness. The small post is power from the ignition switch if no power her with the key on the crank position check fuses, park/neutral safety switch and it's related wiring.

Have your alternator tested.Your car will not stay running if the alternator is not producing enough power to keep the battery charged.Also have your battery tested and fully charged.Make sure your cables are in good shape.

Turn the ignition and the engine barely cranks

You could have a starter that draws too much amperage or a bad ground. Check your grounds at the battery cables and check that the battery is fully charged. You may have an alternator problem. If the battery is fully charged check the starting and charging systems and that will tell you your problem.

How to jump start a 2001 Toyota prius?

The gas engine is the same as an ordinary engine,be shure to remove the key out of the ignition,then connect the positive lead first to both cars and last the negative lead[dont let the leads touch.Fit your ignition key and start as normal,when it starts remove the negative lead first and then last of all the positive lead.To be honest give the battery a good charge once every 2 months as an alternator will never fully charge a battery...

1996 chevy cavalier

1- If the battery is old, some of the cells are dead then it can never be fully charged. 2- There is possible current leakage when the key ignition is out. Here is a check. 3- Take off the wire connection to the alternator. Take off the car key. Use a Multimeter set to current measurement To measure in series from the positive terminal of the battery to the positive cable. ( of course you have to take off the positive cable from the battery.) Your measurement should be less than 15mA, Higher than that you have shortage some where. Starting take off all fuses. one at a time to see the leakage measurement reduce to locate which path is leaking. 4- Keep the measurement set up like this, connect the Alternator wire inis place, look at the muleteer to how is the leakage current measurement. Sometimes the diode in Alternator circuitry leak allow the battery current flow back to the alternator causing battery current drainage. 5- Due to some work involved in testing to find out leakage current, You better be sure your battery fully charged to stay with statement the battery is really good but draining current because of some leakage.

Ignition key switch

You have to use a pin or paper lip to insert in hole in igmition switch to release the lock cylinder. The key has to be in "on" position I think.

Removal
  1. Disconnect battery ground cable (14301) .
  1. Turn lock cylinder key to RUN position.
  1. Place a 3.17mm (1/8-inch) diameter wire pin or small drift punch in hole in upper steering column shroud (3530) under ignition switch . Press retaining pin while pulling out on ignition switch to remove it from lock cylinder housing (22074) .
Installation
  1. Install ignition switch by turning it to RUN position and pressing retaining pin. Insert ignition switch into lock cylinder housing . Ensure ignition switch is fully seated and aligned in interlocking washer before turning key to OFF position. This will permit cylinder retaining pin to extend into lock cylinder housing hole.
  1. Rotate ignition switch, using lock cylinder key, to ensure correct mechanical operation in all positions.
  1. Connect battery ground cable.
