SOURCE: wont start help!

Recheck the charge on the battery,make sure it's fully charged.Check all connections at the battery and at the starter.Possibly a bad starter.If the starter is ruled out,then look at the teeth on the flexplate/flywheel.I would remove the starter and test it.

Make sure oil level is adequate.

Also, this could be an exhaust leak that is being closed as the manifold and/or block heats up.

SOURCE: i bosst my baterry due to dead pawer,sudenly it

Did you determine the cause of your battery going dead in the first place? Did you hook the cables to your battery correctly? What is happening in your car now?

Several things might have happened. I can only speculate from the limited information you gave. You could have had a short under the dash which caused the battery to discharge in the first place. You could have hooked the booster cables up backwards. If you will post additional comments, I will try to help you further. Out of curiousity, have you recently installed a new stereo system or amplifier?

SOURCE: where is the knock sensor, 2004 escalade

Beneath the intake manifold, which has to be removed to gain access. After removing, you'll see a plate with 2 circular covers with wires coming out fo them. Both of these are your knock sensors.

What would a knocking machine gun sound be under hood. I just started it and somewhere under the hood is a LOUD Knocking like a Machine Gun sound.


Is it metalling sound ? if that's the case then don't drive it .. you might be having issues with connecting rod or the bearings in the both cases engine will seize. Consult a auto technician, but you wont have engine light on due to this.

If it is knocking due to misfire (which is mostly the case as the engine light is also on) .... than find which cylinder have the issue then clean or replace the spark plug. If you can get a scanner to read the car computer it will solve the issue in a blink. Otherwise start the engine ... open the hood .pull out spark plug connector one by one and notice the change in sound... the one that is bad will have no effect on the sound.

This could also be the anti theft security system (passlock) shutting down the starter. This is a common GM problem that effected Escalades from 1999 to 2007. When the anti theft starts to fail, it gets confused and locks YOU out instead of just theives. The fact that you can start it at the starter helps prove this "theory". Another indicator would be if you saw a light on the dash that says SECURITY or a picture of a little car with a padlock thru it. This site explains the whole security thing and offers DO IT YOURSELF ways to fix it.

Cadalac escalade, when key turned on,engine not


It could be the fuel pump pressurizing the system. Does the sound stop after a few seconds? If it is the fuel pump then it is a normal sound. Fuel pumps will resonate in the tank when you are low on gas, making them sound louder. If it is more than a hum then I would get it checked out.

Yes the key needs to be reprogramed to the car. Unfortunately that will have to be done by the dealer. Make sure that you have plenty of proof that you are the owner. They will reprogram it but you will not take posession of the car until you prove it is yours.
