sounds like your cv joint is worn out if its front wheels

open the hood and check for leak on any plastic vacuum lines.

There should also be another fuse panel on the interior located on the driver or passenger side foot panels or there about.

I would check for broken wire/wires in the heavy rubber boot that flex's everytime you open and close the door. at frt. of door all the wires run through it to door from cowl. very common problem on both sides

Here is the definition of the code.P0101 GMC Description The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).The temperature of the hot film is controlled by the ECM acertain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the ECM must supply more electric current to maintain the temperature of the hot film as air flow increases. The ECM detects the air flow by means of this current change. Faulty mass air flow sensor- Intake air leaks- Dirty mass air flow sensor- Dirty air filter- Mass air flow sensor harness is open or shorted- Mass air flow sensor electrical circuit poor connectionRead more: http://engine-codes.com/p0101_gmc.html#ixzz223ibNx6tRead more: http://engine-codes.com/p0101_gmc.html#ixzz223i9HR3J

Hi,

This was originally posted here.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

You need fuel, spark at the right time, and compression for the engine to run.You'll have to figure out if it is a fuel or ignition problem if the compression is ok.The list includes low fuel pressure, cap-rotor-wires, spark plugs, coil, ignition module, various relays and fuses, and the computer.Even the key switch could be faulty.I would check for trouble codes first.

You'll need a 12mm wrench or 12mm socket wrench.

Could be one of two things, maybe both, either the water pump isn't doing it's job right, or the radiator is clogged. In either case, it should be replaced.

pull knob off is it broken on back side? it may feellike its working but not if cracked

its letting you know that something is wrong in the brake system, it could just need fluid, check that first , if that doesn't correct the light coming on, have the brakes checked by a shop

if you had a check engine light on you need to erase the code or the voltage regulator switch stays turned off and wont let charge
