2005 gmc yukon won't turn over even after replacing a new battery

I drove the vehicle and parked it i came out later to start it but it would not start I checked all the battery cables all tight. Still it didn't start so i purchased a new battery. The lights and all work perfect but the car does not turn over once the key is in the ignition. no clicking noise or attempt to start. what may be wrong?

Sometimes the problem has been the ignition switch power to starter. If you have checked that, then:
This procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

Does the security light come on? You might have to sit there with the key in the "ON" position for 10-15 minutes until the security light goes off to reset the security system.

i had the same exact problem with my chevy s-10, but once i replaced the battery it ran fine no problem, u may have fried some circuits and relays while jumping the car, and alot of times that clicking noise is your relay burning out, did your car start doing weird things too? like ejecting cd's, flashing lights really fast and weird noises?

make sure the wheels are straight.. if you park them with them turned to one side the steering column is under a bind.... if they are turned all the way to the right you will for example have to turn it a little to the left to release pressure as you turn the key...

SOURCE: 97 gmc pickup, 5.7 eng, fuel pump not operating,

What you need to do is check you fuel pressure. Go to a local auto parts store and buy a fuel injection pressure tester. The pressure fitting is on the top of the motor its a 3/8 ish sized metal line and has a screw on fitting like a tire valve does. This line comes up from the back of the motor to the right of the distributor and goes down into the intake. Make sure to have a rag handy to catch the fuel seepage. After you connect the pressure tester turn the key on and off three times and read the gage you should have atleast 58 pounds of pressure. If you have 56 pounds it won't run because the fuel injectors are a poppit valve style and need atleast 58 pounds of pressure to operate.

My guess would be the anti theft security system. When this system starts to fail, it turns off the starter from the ignition. The fact that you can hard start it proves this.

2005 gmc yukon security light on cluster is on


The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. These 3 parts are in CONSTANT communication. If the key is in the ignition, these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle.
