Engine will not crank over

This is caused by a low battery or a bad connection. You will need to check the voltage at the battery and on the positive terminal on the starter. Both should read over 12 volts on a meter.

The problem appears to be temperature related. A starter relay comes to mind as a good place to start. When the car is acting up, use a test light, and check for voltage on both sides of the starter relay. Also check for voltage at the SMALL wire on the starter while a helper turns the switch to the START position. If ther eis voltage getting to the starter, then the solenoid is the problem.

Also, do not overlook obvious items like clean and tight battery terminals.

At this point it's not starting. What is happening? Does the starter grind when you try? Does it do nothing? Does it spin but not turn the engine?

Since you have been having issues, I'm starting to question the flywheel itself. It may be damaged or even cracked.

Here is a link that shows in general how to replace the starter. Take a look and see if there is anything that you may have missed.

Next, here are directions that show how to check the starter and flywheel. Pictures 1 and 2 correlate with these directions,

STARTER DRIVE/FLYWHEEL RING GEAR INSPECTION
1. Remove the starter motor.

2. Check the wear patterns on the starter drive gear and the flywheel ring gear. If the wear pattern is normal, install the starter motor.

3. If the starter drive gear and the flywheel ring gear are not fully meshing and both of the gears are scored or damaged, replace the starter motor. If necessary, replace the flywheel.

Here are the manufacturer's directions specific to this vehicle. Take a look through them also. The remaining pics correlate with the directions.

REMOVAL

WARNING: WHEN PERFORMING MAINTENANCE ON THE STARTING SYSTEM BE AWARE THAT HEAVY GAUGE LEADS ARE CONNECTED DIRECTLY TO THE BATTERY. MAKE SURE PROTECTIVE CAPS ARE IN PLACE WHEN MAINTENANCE IS COMPLETED.

1. Disconnect the battery ground cable.
2. Raise and support the vehicle.

INSTALLATION

1. Follow the removal procedure in reverse order.

NOTE: When the battery is disconnected and reconnected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.

If the starter sounds like it is turning slower than it should, start by taking the vehicle to a nationally recognized parts store and have them load test the battery. If the battery is good, have them check the starter draw when trying to start. It may be going bad and pulling too many amps.

Let me know what you find.
