I bought an 83 Gmc sierra classic 1500 and it was a fixer upper but ran great I recently changed the fuel tank straps on it and now there's low voltage going to the fuel pump so my truck won't even start any more, and when it does run it runs for a minute then quits if I follow the pump wire to the hood it has low voltage at the front too, I don't know what the issue is but I have a feeling it may be the fuse but I don't know where that is located please help
