Vehicle has power and wont start the key is not in

tHIS SOUNDS LIKE THE SOLENOID IS NOT WORKING CORRECTLY

If the fuses are ok, then check all main relays, then I would say its the ignition switch, if no power to anything. The ignition switch supplies and controls about 50 percent of your vehicle's total power needs. Its worth a try.

your battery is to low in power to start car or your starter or solenoid has packed it in .

Does it do anything when you try to start it? Like make any noise? if so what does it sound like? TICK TICK TICK? Or will the keys even go in the ignition? Will the keys turn or not at all?

Possible that the sound can be that the fuel pump is starting up to pump but cannot be observed as a fault. So unless you check for the fuel pressure and the ignition spark the engine's failure to start cannot be confirmed.Also you need to make sure there is no problem with the fuel, fuel filter.Check for error codes that might help to confirm. Finally the battery must be good and should be cranking well with enough voltage for the ignition circuit.

When you turn the key and it makes the tick, does it ever turn over at all? If not and it only ticks then it is most likely your starter. You can also test your battery at a local autozone, oreilley, napa, etc. and they can tell you if the battery is the problem. Also if you remove the starter they can typically test them also if you desire.

Since your lights don't dim when you turn the key, the starter isn't getting power at all. There is a large cable that runs from the battery to the starter, it should have battery voltage at all times. If it does, then check the smaller wire at the top of the solenoid, it should have battery voltage only when you turn the key to start. If that wire doesn't have voltage when you turn the key to start, look under the dash on the steering column. There should be a thick wire (about 12 gauge) that is red with a light blue stripe. This is the start wire. Test it for voltage when you turn the key to start. If you don't get voltage there, replace the ignition switch. If you do get voltage there, try starting it in neutral. The gear selector switch interrupts the starter circuit if the car is in gear so you can't grind the starter in gear or start it in gear. If this switch gets a bad spot on the contact, it can keep it from starting. It will only allow the starter to work in park and neutral. If it starts in neutral, then you need to replace the gear selector switch. If you get voltage at the ignition wire under the dash and it won't start in neutral, then you need to trace out the wire from the starter because it has a break in it and will have to be replaced.

Ok then, from your description and the
make/model/year of the car you have there,
it appears you've reset the VATS.

The car's security immobilizer
reader at the key switch
does not recognize the coded
chip in the ignition key any longer.

You can try to put the key
in the ignition, turn to the on position &
wait at least 10 min like that.
(Do not turn off the key switch before
10 minutes as elapsed!)

Once done, the key is re-programmed and
should allow the fuel injectors to work again.
The car would start now if corrected.

In some cases, the VATS (GM'S VEHICLE ANTI THEFT SYSTEM)
will re learn the code this way, and will then
allow the restart, however if this does not work,
then you can simply tow it to any GM vehicle dealer
to have the service department re code it.

There is a permanent solution though.
Adding the PLJX Self learning Bypass module (59.95)
will bypass the PASSLOCK system in your vehicle
for good. See this at www.PASSLOCK2.com

Good luck I hope method 1 does the trick!

Here is the 30 min relearn:

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.

You have a dead battery. It needs to be replaced. What you hear, are the low voltage relays trying to activate.

That sounds like a dead battery. The ticking sound is the relay (a type of switch) which enables power to the starter motor when you turn the key. If the battery is weak, the relay will click, but there is not enough power to turn the starter motor.
