CHEVROLET MONTE CARLO FUEL SYSTEM

My Car Takes Gas Very Slow Pump Keeps Clicking Off Every Dollar I've Tried Adjusting Lever In And Out Nothing Helps

The Fuel Supply Line Is Leaking At The Fuel Rail When The Engine Is Running Do I Need To Replace The Fuel Line Or The O-ring?

Had A Rodent Issue Got All Wiring Repaired But Now I Have No Signal Power To The Relay For The Fuel Pump And No Signal Power To The Starter...
