If your talking about the fuel pump, there is no shut-off switch. If your sure it is the fuel pump, check the fuel pump wiring for voltage and ground, engine cranking. Gray wire is voltage, black is ground. The pcm B fuse is in underhood fuse block. If good voltage and ground at the fuel pump with no fuel pump action or fuel pressure, suspect the fuel pump.

SOURCE: Low Beam Ligths on 2004 Chevrolet Trail Blazer not Working

Check fuses & bulbs first, The headlight bulbs may be twin filiment type in which case the lower filliment may be blown & the upper filliment or highbeam will still work in this case replace your bulbs. But these models are renowned for having negative earthing problems. Follow the negative (-) or black lead from the battery to the point it is bolted to the vehicle. make sure there is good metal on metal contact with the negative lead & the vehicle. Then check the negative that comes out of the lowbeam headlight socket insure clean metal on metal contact. If you still cant find a fault, contact a chevy technician.

Do you think the sound originates within the passenger compartment or possibly from within the engine compartment? There is not much that might knock inside the car . If it knocks every time you switch off I would suspect the engine compartment and a mechanical cause.
Might be something a loose component, maybe the exhaust hitting something as the slowing engine vibration causing a harmonic at a certain point. Possibly, but unlikely, an engine mounting.
Have somebody assist you to trace the source of the sound, it is hard to do alone.
There used to be an Audi advert in which a sound could not be traced and it took an expert to track it down. (He had to oil the pendants on the woman driver's earings!)

Where is the fuel filter located on my 2004 Chevy Trail Blazer? WE

On 05+ Trail Blazer, the fuel filter is integral with the fuel pump inside of the fuel tank. It is a non-serviceable part. On 02-04s, the filter is on the drivers side frame rail at about the B-pillar. If your trail Blazer is a late 04 which means that it was build close to the 05 Trail Blazer, you may have a non serviceable fuel filter. Good luck and check under your Trail Blazer or look at your manufactured date sticker on the door which would help you indicate if your 04 is a early Trail Blazer and you'll have the fuel filter on the inside frame rail under the driver's door.

How do I find out if there is a warranty on my OEM ac delco battery that came with my 2003 GM Trail Blaser?

I highly doubt that the warranty is still in effect, but it never hurts to check. I would recommend contacting a Chevrolet dealer to find out what is still covered. If you do need a new battery, Autozone sells a good selection with a range of prices. Their warranty is also very good. They replaced a couple of batteries for me even though it was my fault they failed.
