SOURCE: service engine light staying on

Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

I have a 2002 yukon denali. Somehow my viper alarm needs reset. I cannot start the truck. When I replaced the car battery it was fine. Now when I press the buttons on my remote it does not do anything....


Your 2002 Denali is equipped with a security system from the manufacturer. The installation of aftermarket security systems such as the one you are describing is just trouble waiting for a place to happen.

General Motors has published several Technical Service bulletins regarding such aftermarket equipment and warns of the problems that can occur including No-Start conditions, trouble with the keyless entry system, engine misfire problems, transmission shifting problems and severe damage to high-dollar parts like catalytic converters.

My professional recommendation is to remove all of the aftermarket equipment from the vehicle and resore the vehicle wiring harnesses to a condition that would be acceptable to the people that built the vehicle.

My 2002 yukon cranks but does not start on 1st trun of key but will on 2nd?


Turn the key on and listen for the fuel pump to run for about 2 seconds. If you don't hear it run the may be a problem with the fuel pump relay or its cicuit. The extra cranking from the first and second try builds up oil pressure and that will energize the pump through the oil pressure switch.

If the pump runs for the two seconds try to start it on the first key turn. If it still does not start there may be a pressure or deleivery issue. So many vehicles no longer have external servicable fuel filters, yours may not. If it does though you may want to change it.

Also, does a security light come one and saty on in the dash?

I have a 2000 Yukon Denali and the alarm system will not alow it to start at times.....What should i do whwn this happens or how can i prevent this from happening


According to my lists, 2000 Yukon has a Passlock 2 anti theft security system. This means that the key literally has a transponder in it that sends a radio signal to the ignition. The ignition/lock cylinder then sends a signal to the TDM (theft deterrent module) which then reads the signal and allows your truck to start. If there are any communication breaks, the truck thinks its being stolen and goes into anti theft.... Read up on this link. There might be an option for you. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Needing to know why my Yukon's gauges stopped working.


You need to replace cluster, 99-02 Silverado GMC all will work even if it has a trans temp truck is pre wired for it. I put a 02 Denali cluster in my 01 silverado no problems. GM can reprogram hours and odometer if you want.

The needle on my gas gauge (99 denali) shakes when I turn on the engine. Anyone heard of that?


Mine wouldn't start if the temp was below freezing outside. Dealer tracked problem to after market alarm system that was installed to the main wiring harness. He de-installed the alarm system and replaced the wiring harness. Like magic that and 4 other incideous little problems disappeared.
