Ask Me Help Desk - My toyota camry won't start

It has only happened once so far... but it would not turn over even though I had battery operating. Finally, after several attempts, it started and has been starting ever since. I was told that the mechanic would not be able to diagnose unless the car is not operating. I would like to fix it before I am stuck somewhere.

If it cranked but would not start, I would replace the coil. If it would not crank, I would install a starter motor, remanufactured by Toyota. It would've helped to know the year and engine.

Thank you. It is a 1997 with 157,000 miles.

Yes, I would replace the coil for a crank but won't start situation. Best to go OEM.

I'm sorry I didn't give all the information. When I tried to start it, there was no crank at all. Total silence. All electrical on (dash board, etc.) but it was as if there was no electrical.

"Car (Starter Motor) Won't Crank"

. Ensure the battery is fully charged, before diagnosing starter problems. Then, test each cell, with a hydrometer or multimeter, to ensure that it’s good. This important step is often overlooked.
. Test all under hood and under dash fuses with a test light or multimeter.
. Ensure the gearshift is in Neutral or Park (automatic transmission), or the clutch pedal is depressed (manual transmission), if the starter motor does not turn at all when the ignition switch is turned to Start.

1. If the starter motor doesn't turn, but the starter solenoid (relay) "clicks" when the ignition switch is turned to Start, the problem is with the battery, starter solenoid, or starter motor connections.

2. Disconnecting the negative battery cable first, clean battery terminals and cable connections with a battery terminal brush, No. 240 abrasive cloth, or steel wool. Also, check the battery ground cable connection to the body and engine. Apply silicone dielectric grease, when finished. Examine the cables carefully for hidden corrosion or internal breaks.

3. While the negative battery cable is disconnected, clean starter motor and starter solenoid connections. Apply silicone dielectric grease, when finished. Make sure all connections are secure. When installing the starter cable, make sure that the crimped side of the ring terminal is facing out. Reconnect the negative battery terminal last.

4. If the starter motor spins but the engine is not cranking, the overrunning clutch in the starter motor is slipping and the starter motor must be replaced. Also, the ring gear on the flywheel or drive plate may be worn.

5. If the solenoid plunger cannot be heard when the switch is actuated, the battery is bad, the fusible link is burned (circuit is open), or the solenoid is defective.

6. In order to check the solenoid, put the transmission in Park and remove the push-on connector from the solenoid “S” terminal. Connect a jumper lead (12 AWG), or preferably a remote starter switch, between the positive battery terminal and the exposed “S” terminal on the solenoid. If the starter motor now operates, the solenoid is fine and the problem is with the ignition switch, neutral start switch, or wiring. If the starter motor still does not operate, replace the solenoid.

7. If the starter motor cranks the engine slowly, ensure the battery is fully charged and all terminal connections are clean and tight. Then, check connections at the starter solenoid and battery ground. The engine will also crank slowly, if it’s partially seized or has the wrong viscosity oil in it. Synthetic engine oil allows starter motors to turn the engine over easier and faster, thus promoting starting and reducing battery drain.

Wow, thank you so very much for such a detailed answer.
I appreciate your time and willingness to share your knowledge.
Thank you.
