I have a 1992 Chevy S10 4.3 V6. I replaced the Fuel filter, fuel pump relay, and fuel pump and it still doesn't run I know it is a problem with the fuel because, I can put some fuel in the carb. and it runs until it burn what I put in. I used a test light to test the fire going to the tank, it has a plug where the hot and ground wires are coming down the rail of the truck that plugs into the wires going up to the pump, It shows a good bright light on the side coming from the rail and a poor weak light on the side going to the pump. The guy at the auto parts said to cut the plug out and wire it stright, so I did and it is still the same ( bright on one side and weak on the other) does anyone have any ideal what it going on. The only other thing I can think of is I got a bad fuel pump at the parts house or it has a short in the line some where.
