Hey,I have an 03 chevy s10,I recently tried putting a pig tail on it (straight wired) and had no luck,gave up and crimped all the wire back together,and today a guy at work noticed I had no taillights,but...


I would check your tail light fuse first then test the brown wire in the tail light harness where you origionally cut into it. With the lights on there should be around 12v on it. if not you may have pulled the wire too hard and broke it upstream. Test to see if there is 12v at the fuse ad if there is, your trouble should be in the wire between the fuse and the spot where you cut into it.

The fuse for my tail lights and dash lights in my 91 Chevy S10 Blazer constantly burns out. I put a new one in and it burns out within a couple of minutes on the road. What's up with this?


you most likely have a wire short or a wire cross. Look for any wires that may have the insulation open and lying on metal. check the battery compartment and the battery cables to make sure they have not been pinched against something sharp. look at any recent parts you have replaced to make sure you have not accidentally smashed (grounded) a wire against the frame. also make sure the fuse is the correct amperage, and make sure that some small amount of debris hasnt lodged itself into the fuse box where the fuse plugs in. (do not attempt to dig any debris out of the fusebox without first disconnecting the negative cable from the battery, then the positive cable.)

2001 s10, fuel pump would not come on. i replaced with new one, fuel pump still wont come on. what is next


I ran into the same problem and solved it. To replace the fuel pump I had to remove the bed since the fuel tank is under it. I had to disconnect the tail light wires including the ground wires. One side had 1 grounding wire and the other had 2 grounding wires. After a month of messing around with fuses and sensors I found out that one of the (Two ground wires) next to the left tail light was actually the (Fuel pump ground wire). So if you don't know which one I am talking about, make sure you connect ALL the tail light wires and plugs before cranking up the engine. This was my luck with the s10 2001 and good luck to you :)

My tail lights on my 1991 Astina dont work!


It would appear that it is a wiring problem, and I would guess that it would be the power supply wire since so many things are not working at the same time. You need to identify the wire that carries the power back and especially look for connectors since corrosion might be your culprit.

Need a wiring diagram for a chevy s10. brake


your power starts at the brake light fuse,check with a test light,then proceed to stop light switch on brake pedal under dash,one wire will be hot when when you check it with your test light, the other won't be until you press down the brake pedal then the power flows through to the second wire,if no power to second wire replace switch,if you have power remove tail light bulbs and check for power in side socket.

Have a S10 PICKUP, have brake lights, turn signals, but no tail lights, I have bought new bulbs


Use a test light to check the wires back to where you have power. It must be shorted out somewhere, probably near the back where gravel sones can hit them. Check your fuses. Also, if you have an aftermarket trailer towing plug on your truck , that will be a good place to start looking for a short.

1991 lincoln town carTail lights and turn signals stopped working


One of the tail light bulbs can be shorted internally.  Replace the tail light bulbs first.  Try this cheap fix first.
