If a starting circuit malfunction occurs, check the 
Battery Cable clamps, battery cables, and battery condition before blaming the starter. Ensure the starter mounting bolts are tight and the Digital Transmission Range sensor or Clutch Pedal Position switch is adjusted correctly. Check the starter relay operation, located in the engine compartment fuse and relay box in later models. If the starter motor spins but doesn't turn the engine over, replace the starter motor. If the starter motor doesn't operate but the relay clicks, the issue could be the battery, relay contacts, solenoid, or motor electrical connections. If the relay doesn't click, the battery may be discharged or the relay circuit or relay may be defective. For early models, check the starter relay circuit by using a jumper wire. If the starter motor operates, the issue may be the ignition switch, Neutral start switch, starter/clutch switch, or starting circuit wiring. If the starter doesn't operate, replace the starter relay. If the engine cranks slowly, ensure the battery is fully charged, all connections are clean and tight, and consider a short to ground, partially seized engine, or incorrect oil viscosity.
