Car wont start or crank properly (Video)
For example, if I drive to the store to pick up something real quick, I turn off the car and when I come back to try and start it, it doesnt start! It doesnt crank or anything it just clicks. I have to wait maybe 30 mins as the car rests and then it starts!
Im guessing it has to do something with the engine being hot? It does this to me when I turn off the car to run a quick errand and when I come back it wont start. I have to wait... Have anyone ever experienced this?

Re: Car wont start when engine is hot
When the ignition switch contacts heat up(driving the car), the solder joints open, similar to what happens to a main relay, and they fail to function. After cooling down, the contacts close and work again.

How much does it cost to replace the electrical components while retaining the key locks?

Re: Car wont start when engine is hot
In that recall, the ignition switch is faulty in the on position contacts. I don't know what kind of car you have, but I had an aftermarket ignition switch that went bad after only 1 year and had the same symptoms you had. This is how I know about this. I pulled another from the junkyard and swapped it in and I was good to go. My original ignition switch wasn't even bad, but I bought the aftermarket one and just tossed my oem one.
Normally you just remov the lower ignition cover/dash cover and there is two 6mm bolts holding the ignition switch to the steering column. The other end has a connector that you disconnect.
There is a small chance that your battery terminal has a small film on it that is preventing a good contact. This is caused by a leaking/old battery going bad. Check that first. Sometimes you can't see the film. If not, then I would swap out the ignition switch.

Re: Car wont start when engine is hot
It's best really to get it from Honda as it's only around a $50 part from them which is pretty cheap.
www.hondapartscheap.com is on the west coast
www.hondapartsunlimited.com is on the east coast
get it from whichever place is closest.

Re: Car wont start when engine is hot
More details are needed. When did you install a new battery? Before or after the problem started?
And has the alternator been tested?

Re: Car wont start when engine is hot
Yes the alternator works and it charges the battery. I brought my car to a local parts store, they hooked up the battery connections and tested it on my car. Everything looked fine. I still bought another battery with more crank power just in case and replaced it. The problem occured before I bought the new battery. Thats why I bought a new battery just in case it needed more crank power. The alternator has not been tested but from the battery test, the guy at the local parts store says its running fine. I also removed the negative battery connection while the car was running to make sure that the alternator was working and the car still ran.

Measure voltage across the 2 battery posts with a multimeter and have the alternator tested.
Never do this^ test. It's a great way to damage sensitive electrical components.

Re: Car wont start when engine is hot
I will post up another video soon! Sometimes when I crank, it makes a high pitch screeching noise on the third key turn that sounds awful then it starts. It sounds like a grinding sound but its definitely not the alternator belt being lose or a/c or p/s belts I replaced those also
Yea I only did it one time for this test but the problem is the same before and after

Re: Car wont start when engine is hot
Again, the problem sounds like a battery low on charge due to a weak alternator. If you are unwilling to do basic diagnostic tests, then you may be dealing with this problem for the long term.

Re: Car wont start when engine is hot
When you have an issue and you are telling it to people that can only rely on what you tell them, you need to be as detailed as possible on what is happening and when.
When you started this thread you said it wasn't cranking at all, now you are saying it also has been cranking. This has a big bearing on the advice you get.
You need to start the car and test the voltage to determine if the alternator is not properly charging the battery which could be causing your car to not start.

I already said I took it to a local parts store and they tested the battery while it was on the car and they said all connections are good. They tested it while the car was off and starting the car. I was going to take off the alternator to get it checked at the local parts store but the man who tested my battery said it wasnt necessary because he checked the voltages with his multimeter and battery load hand computer..
I have been working on Hondas for a long long time and done many swaps. I am not new to swapping motors and diagnosing problems but I really cant figure this out.
More info: 97 Civic CX hatchback with JDM b18c completely stock with P/S A/C running on a p72 obd2 ECU with all emission components connected, BARD and no check engine lights. I did all the work myself if that helps

Re: Car wont start when engine is hot
Im going to start looking into other causes such as ignition coil, distributor cap and rotors, new spark plug wires, clutch switch, main relay fuse, there are so many things to check. And the cause of a high screeching, grinding noise at times right after the motor turns and starts. Maybe its a mechanical problem instead of a electrical problem that physically wont cause the motor to turn
