I was removing the battery from my 2002 buick le sabre and the battery post broke in positive battery connection and I can't seem to get it out. How do I replace the positive battery cable?

1. Disconnect the battery negative cable.
2. Raise and support the vehicle. Refer to Vehicle Lifting.
3. Remove the torque converter cover.
4. Disconnect the battery positive cable from the starter.
5. Disconnect the wire from the solenoid S terminal on the starter.
6. Remove the 2 starter motor mounting bolts.
7. Remove the starter motor.

Verify that the foot pedal has returned to its off position. Lube with WD-40 all connection areas of the parking brake cable especially where it enters cable shielding. Remove rear tires, beat all around outside of brake drums to release brake springs. Remove drums, clean all spring assemblies with brake cleaner and free parking brake cable assembly with spray lube then coat with fresh grease. Replace hubs, check for proper operation, if so re install wheels.

Only Ford products have an inertia switch.
If the pump does not work, you would need to check for voltage at the pump relay and the connector at the gas tank.

Ground Wire?

Your entire body,all fluids, engine block,trans
etc, are at ground potential

Electrons (Amps/Current) travel thru the body
& return to the Battery on the wires.

All Black Wires are grounds
All come from the Battery Negative Post

Dead battery? Battery connections? Is it turning over? More info.

Check battery connections and make sure they are clean and tight.
IF they are and the battery is tested to be good by a battery load tester, then
the starter could be going bad.

Starter could be bad if the connections to the new battery are good.

those wires are probably going down to the crank sensor if that sensor fails then the car will not start so fix the wiring and try replacing the crank sensor.

You have to have a tool that puts pressure on the piston and turns it clockwise at the same time to to push it back.
