Question about 2000 GMC Envoy

Open Question

2000 GMC Envoy No Start

When entering and starting this vehicle, if the driver is not in the vehicle with the door shut, vehicle is immobilized when key is turned (Yellow Security light stays illuminated) I do not have a keyfob to arm or disarm this vehicle and have tried to disconnect the battery but have had no luck. Other vehicles that I have had this concern with I have turned the key in the drivers side key cylinder to lock then unlock and it disarms the system. When I do that, the light goes out, but still no start - The fuel pump is not making noise when key is turned. I believe the immobilizer system to be cutting power to fuel pump. How do I deactivate this system with no keyfob? Thanks

SOURCE: my immobilizer will not disarm

when you say "the immobilizer will not go off" that mean you can still drive the car or not,when the immobilizer goes on you can start the car but will not run, so what do you need a spear key for .you may need the valet key, is a gray key .
I am professional car alarm and remote start installer so I deal with this kind of problems if you have any question email me

SOURCE: keyless remote wont work, vehicle completely shut down

Hi Russell,

Absolutely no power? No dome light? No head lights? Nothing?
When you step on the brake pedal, no brake lights?

If true, start at the source and pop the hood.

This is going to be a bit of back and forth dialogue. I'll ask some questions and you get me the answers. That way we can get to the root of the problem. To save time, I'll ask multiple questions at a time. Here goes.

  • Check the battery. Is it still there? (Valid question with no evidence of power)
  • Are the terminal clamps tight?
  • Are the terminals clean and free of corrosion?
  • Are all the belts in place and tight? (pay special attention to alternator)
  • If you have a voltmeter. test the voltage at the battery terminals. It should be +12.5VDC.
Try getting a jump, when the cables are attached does anything light up?
Does it turn over and start?
Does it do anything?

Comment me back with your findings

My 2004 GMC Envoy's radio wont stay on after shutting the vehicle off

This function is called delayed exit, and it is signaled by the door ajar switch of any door that is opened. The system needs to be scanned with a special scanner by the dealer to see if the switch is defective in one of the doors. Since the switches are in each door and mounter inside the door on the latch it is not practical to guess and end up taking poss all the door panels off before you find the one that is the problem, if that is what the problem is to start off with, others things can cause this like a defective exit module or a shorted wire to the chassis or a broken door harness wire inside the insulator where it goes from the body post to the door.
