Question about Chevrolet Cars & Trucks
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.

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.
