Does fuel pump run ? Remove fuel cap. Have someone crank it for you,you should hear fuel pump running. If not bang on bottom of tank while cranking. If it starts fuel pump will need replacing , if not check for power to pump, if it has power,replace pump. If no power, check relay for operation

hi for info the brakes warning light on dash is also an indication that brake fluid level is low? or there may be a leak resulting in fluid level drop ? also considering age of car you may need to inspect brake pads wear ? if your car has low brake pads wear indicators attached to pads ? or the hand brake switch req's checking to ensure it is being pushed to off position when h/brak is down ? so fluid level low is the obviouse 1st check as fluid will displace from reservoir as pads wear low hence the level indicator on fill cap trips on may i suggest if it is low level b4 you top up? check your b/pads if you have not done so recently? or replaced since new ? hope this helps you locate problem best wishes from the uk

I don't know if you already fixed it, but I had the same problem on my 03 yukon, TysonRicky is right. In my case it was the blower control module. You can find it right under the glovebox. It cost me close to $100 for a new one, but very easy to replace. Can't even imagine how much it would've cost me if I had a mechanic do it.
