Grounds from the engine to Chassis and also make sure you have a clean connection from the battery terminal to the post.

Try jumping the starter at the junction box on the front right inner fender. Not sure which terminals need to be jumped. Someone else may know. This will rule out a bad ignition circuit or a bad neutral safety switch. Your car is in park, right?
You could have lights etc and still have a bad ground from chassis to engine causing the starter not to function.

Busman, did jumping the terminals solve the no-start when hot problem?

Never did that.....
You are meaning "jump" as in with a battery charger or another car battery? The only things on my inner right fender are reservoirs for washer fluid and overflow for coolant.. ???? ...

No. Jump as in 'connect the two terminals together with a piece of wire'. It's a wire junction box covered with a plastic cover. Look down, kind of below the hose feeding air to the air cleaner.

My first suspicion would be the starter solenoid. Use the blunt end of your lug wrench to momentarily jump the hot connector at the solenoid to the heavy connector on the starter itself. Make sure the car is in neutral before doing this.
This should bump the starter. After this, see if it will turn with the key. If it does, the problem is probably the solenoid, but you would be best served by replacing the entire starter including the solenoid. Good luck and hope this helps. |
