So, you have a new battery and no lights come on? Do the dash lights work at all when you turn the key on?
You gave such little info to go on. It is possible that a main fuse or fusible link is blown. Have you checked the fuse panel in the engine bay. You also gave no clue as to what make, model or year you have. Why did you replace sensors?
check all the wires from the battery to the engine. sounds like you may have failed to hook up the main hot cable or ground cable. the main positive cable hooks directly to the starter solenoid but there is also another slightly smaller wire thats attached to the starter in the same place that supplies power to the rest of your buick. I'd check for the missing connection first.
yeah, resubmit with year, make, model and exactly which sensors you replaced and why.
What abt the battery? How abt the battery cables?
