Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
Engine won't start	Battery, starter, fuel pump	Check battery voltage, test starter, verify fuel pressure
Poor acceleration	Clutch slip, fuel delivery	Inspect clutch wear, test fuel pressure and injectors
Brake vibration	Warped rotors, wheel balance	Measure rotor runout, check wheel balance
Electrical issues	Ground connections, fuses	Inspect ground points, check all fuses and relays
Transmission noise	Low fluid, bearing wear	Check fluid level, inspect for bearing failure
