Horn is under the front headlight light, which would have to be removed to access or pull the front wheel well liners out and look in just below the running lights. I believe 2 horns. 2008 GMC Sierra Horn Location
Check that the spark plugs are ok, check air filter is clean, check fuel filter. If you go to a mechanic ask the computer to be checked with a code reader and compression to be tested.
Disconnect the electrical connector for the "Water-In Fuel" sensor from the lower end of the filter housing. Then the filter assembly simply unscrews like an oil filter.After the fuel filter is off, you must unscrew the sensor from the lower end of the old filter and transfer it to the new filter. Then screw the new filter into place. There is a screw on the top of the filter housing to bleed the air from the fuel filter assembly. Loosen or remove the screw and pump the hand pum on top of the filter housing until fuel comes out the bleeder. Then tighten the bleeder and start the engine. If you did everything correctly, it should start right up and continue running. If it starts the dies in a couple of seconds, then you must perform the bleeding process again. (SEE PICTURES BELOW)
Hint: Sometimes it is much easier to get to the filter through the right wheel housing. It may be easier to support the vehicle and remove the right front tire to get to it.
If it is gas you will need to buy the fuel pump from the factory or from your local GM dealer, I do not recommend aftermarket pumps as they tend to fail after a short period of time. also replace the fuel sock and fuel filter at the same time, this is called preventative maintenance and will save you problems in the future.
