Can you provide some symptoms? If you're hearing one kind of loud clunk when you turn the ignition switch to "crank", suspect worn solenoid contacts. If there's no clunk, and you don't hear the starter relay click, suspect a defective neutral safety switch. You might need to measure voltages at the starter relay socket. That will split the circuit into four parts.
