On automatic transmission/transaxle vehicles, put gear selector in Neutral or Park. On manual transmission/transaxle vehicles, put gear selector in Neutral. Set parking brake and block wheels. DO NOT remove relay connector. Using a 12-volt test light, check for power between starter relay battery terminal and ground. If power does not exist, repair wiring. If power exists, proceed to step 2).
Using test light, check for power at ignition terminal on starter relay while an assistant holds key in START position. If power does not exist, repair wiring between ignition switch and starter relay. If power exists, proceed to step 3).
Reconnect jumper wire between battery and ignition terminals. Connect a second jumper wire between starter relay ground terminal and chassis ground. If engine cranks, starter relay is good. Check and repair poor ground connection between relay housing and mounting surface. On models with automatic transmission, inspect neutral safety switch for malfunction and transmission linkage for improper adjustment.
Connect a heavy jumper wire between battery and starter solenoid terminals on starter relay. If engine cranks, solenoid is okay. Proceed to RELAY TEST .
If engine does not crank, check and repair wiring between starter relay and starter. Repeat test. If engine still fails to crank, repair or replace starter.
