“I have a 93 s10 Blazer and the truck shut down while my daughter was driving. The ecmb fuse was blown and would blow out when the ignition switch would be turned on. I finally tracked the problem down to the fuel pump. When I removed the gas tank and pulled out the fuel pump, the wire inside the tank were welded together and the plug on the end of the fuel pump was melted (fused) together. This really concerns me that these internal components can get hot enough to melt they could easily cause the tank to explode. …”
