While the CEL is on you need to take it to an autoparts store and have the code read to know what is exactly going on. Just cuzz it seems to be running fine does not mean there isn't something wrong.

My 99 suburban has the service 4wd light on but the 4*4 locks in and everything is working fine and the light came on with the truck running what will be a reason why this happend?


The first thing that I would do is get up under the vehicle and check the lube in the front and rear differential and the transfer case. The 4 wd may still engage but if it is low on lube it will go out soon.

Hello today i leaded out my Chevy Suburban truck to my sister she returned to me with the Service Engine Soon light on ?? Im sure she ran the truck up hill ? What might the problem be it was perfect this...


She didn't do anything wrong at all. Your truck is just fine and doing what it was designed to do. That's a normal indicator that comes on to remind you to get the oil changed. It's supposed to get reset every time the oil gets changed and frequently, Quickie Lube and other instant oil change shops will overlook resetting it. Look in your owners manual under "Resetting the Service Engine indicator light" and you can reset it yourself. Or just get the oil changed and tell them to make sure and reset it.

Service Engine Soon Light comes on but doesn not stay on.


If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.

go to the back of the truck near the gas tank and listen for the pump to run while some one turns the key to the on position not Start but on. If you do not hear the pump it is probubly bad.
