Starter Relay
With automatic transmission gear selector in "N" or "P" position, or clutch pedal depressed with manual transmission; connect a jumper wire on starter relay between battery and ignition terminals. If engine cranks, the starter relay is good. If engine does not crank, connect a second jumper wire to starter relay ground terminal and a good ground. If engine still does not crank, replace starter relay. If engine does crank, relay is functioning, but transmission linkage is out of adjustment, or neutral safety switch is defective (automatic transmission), or clutch neutral start switch is defective or out of adjustment (manual transmission).
