Jump directly from the battery - to a good ground near the engine
Engine cranks strong = bad grond cable / connection
Jump from the battery + to the + post on the starter
Engin cranks strong = bad power cables / connections
Engine cranks slow with both jumpers connected = bad starter or partially seized engine or heavy load on engine
Remove both belts and repeat the above
