It is important to avoid blaming the starting circuit for any malfunction that occurs in it. Follow these steps to make a good diagnosis: Make sure that the
Battery Cable clamps connecting your battery are clean and tight. Check out how well the battery cables are fairing on and get new ones if they have any damage at all. Inspect the battery to see if it has failed in any test; change it, if so. Test the starter solenoid wiring and connections. Ascertain whether the starter mounting bolts are secure. Investigate fusible link, trace cause of its burn and mend the circuit where necessary. Examine operation of Park/Neutral switch; place shift lever in PARK or NEUTRAL position only when you do so. Finally, evaluate operation of starter relay situated in fuse/relay box under hood near firewall between engine compartment and passenger compartment, should contribute a signal voltage from ignition switch does not start starter When ignition key on cranks but nothing happens or starter whines over check solenoid terminal for having 12 voltage with meter or test light attached as helper turn key to start; also must inspect all fuses and relays starting system series, if no reading take out starter for bench testing If low speed turning check voltages while cranking specification ranges during assembly positioned engine as well as current draw If readings fall below specified values then install different one Several things can reduce amount which includes connection cleanliness rating temperature Lastly remove bench examine unit more closely Typically fault lay defective solenoid before moving next step confirm crankshaft seized Rotate this pully first With Starter secured at Jump negative body positive B+ Put turn apply power lockout higher order determine plunger Extend engagement click pressurize activating engage mechanism Then performs correctly.
