On the starter itself. The small diameter wire connects to it to operate it. The large cable applies battery to the motor.

Are you talking about the ignition switch or the key cylinder? The ignition switch is on the steering column under the dash. Changing the key cylinder requires the removal of the steering wheel.

A steering wheel puller can be rented. Some auto parts stores lend the tool for free. The trick is to disable the the air bag so it doesn't go off in your face. Get a Chilton manual to locate the bag electrical connector before you start disassembling the wheel...after you get a new switch from the dealer.

Check the CV joints on the axles.

Fuel filter

Have you changed fuel filter and your TPS Throttle Position Sencor is probly getting ready to stop working usually when you get a hesitation in newer cars with fuel injection its the TPS sencor or filter clogged

check for power to the fuel pump and pump operation. check filter condition. check for fuel in the tank (do not rely on the gauge) check for proper venting of the fuel tank as pumps will not pump if there is a vacuum in the tank

My first guess would be that your fuel pump has died. This is evident buy having no pressure at fuel rail. Check this way, put key in ignition and turn to on, if you hear a whurrrrr noise in back of car your pump is good, if not change the pump. I am assuming all was working before. GOOD LUCK FRIEND.

Hey John the only way to realy check fuel pressure is with a pressure gauge ,I did a motor some months ago and replaced 3 pressure regulaters 2 were no good out of the box also check your vacuum pressure to it.

30+ years as an automotive certified master tech. It is ok. 30 lbs is more than most engines out there for a hot idle pressure.

there would be a drop at lower revs as engine not pumping oil as much so i would,nt worry

An old engine will normally show a lower oil pressure, which may be due to worn bearing, a worn oil pump or both. A new engine with good bearings will normally show a higher pressure at revs than at idle, and a higher pressure when cold. Putting a worn oil pump back in a new engine (never a good idea without a thorough checkup on it) will modify this situation. Just going on the readings I'd say your situation now is quite normal. You may even be able to change to an oil one grade less viscous, say 10W instead of 20W depending on your winter temps.

i have been fooled by this one way to many times. when a wheel bearing or hub assesembly is making noise, it will sound like it is comming from the other side. i do not know why this is. but one test will prove if and which one. when growling noise occurs, notice, when turning left or right, does noise get louder and quieter as you turn? if so then it is wheel bearing. when turning left the right side will make more noise. when turning right the left side will make more noise. if always the same then, tires or transmission need addressing. the cv axle does not make a growling noise, unless front wheel drive car does not move, it makes a clicking or poping noise. sorry but at least you dont have to replace other axle I’m happy to assist further over the phone at https://www.6ya.com/expert/christpher_f760d0f18f8eedc3

inside the lock is too dry ,rusty, just moving the key spray W-40 as mush as you can,wait for a few minutes then move the key on both sides but doing slow ,if this no helps you,go inside of the car and remove the back seat to get in to the trunk to open the trunk so you need replace the lock system good luck

Check fuel level and fuel pressure.

I had a buick that this happened to and I stumbled across this site.. might be your issue.. I seen you car was on the list.. hope it help

Battery and connection,starter,fuel filter.

SORRY,i don not understand what means,the carr stalls,can you please specify more details about the problem I like help,

gm used a pass key system on their cars that WILL FAIL ..it just is a matter of time . you have a system that is failing,, the key uses a resistor (that little thing that is imbedded in the shaft) and that is read by the ignition switch and sends a value to the security box that will then send a signal to the brain to allow the car to start. most likely your ignition is worn and when it is on it has a bad contact on the key .. it will not stall your car,, only when it gets that bad connection at a point when you go to start it you will have a no crank condition. google "gm passkey " or gm security " for lots of info
