Read your response to something similar to my problem. I have a 2004 Cavalier, the trac off light came on yesterday, when I got home I turned off the engine, when I tried to restart it, it did not start, it seems that it's not injecting fuel or somethin like that, could you help me?
What is a coil pack?

One year ago---your check engine light came on The PO405 code was for an EGR Valve issue No mention--- if you had that fixed
A Few Days Ago---you get Trac Light on,that is part of the ABS Braking System Now that system has to be diagnosed & repaired,not just continue to use the car,actually make the repair, before you do some damage or can't stop the car & worse things happen
Changing Trans Fluid---is NOT a FIX for anything,but should be done on all vehicles every 3 years.
If the Engine Management System isn't working correctly,then your trans won't work as it should either
You need to be proactive & immediately have any abnormal operation or check light problems, at least diagnosed in a few days of noticing them
You need to stop using any car that isn't 100% & have it repaired as soon as possible.
Not wait weeks or years. Being 9 years old, the trans may also have it's own issues
I have a 2004 sequoia with the same problem. VSC TRAC, TRAC OFF & brake light comes on at the same time. Sometimes just the brake light and other times all three. Sometimes no lights. Does anyone have a fix?
no you need to take it and have the codes pulled on it, the abs system will disable the traction control system.Without knowing what the codes are for the abs system it would not be possible to say what the problem is.
Hi the trac off light and the car not running have nothing to do with each other
the TRAC OFF LIGHT will set a code in the EBCM
to check the fuel pump remove the gas cap and have someone turn the key to run and while you listen at the filler neck if you can hear a humming noise then the pump is working
if the pump is working then check fuel pressure and spark
hopes this helps you
I had the exact same problem with my 2004 Cavlier. I took it in and the dealer said it was a voltage problem with my speed regulator located in one of my wheel bases. I had it replaced under my extended warenty. I suguesst taking you car to a mechnanic as soon as possible, cause it could be that sensor, or an electrical issue all together. Especially if it is that sensor, since it effects your braking system, traction system, and the overall drivability of the car.
