My car starts on its own with the auto start, it keeps starting and stopping

Scan the ECM for codes, sounds like your in "limp home mode" . SCAN IT!, may be a short too?!

If a aftermarket alarm then disconnect it ,these auto remote start alarm things are useless and all go wrong with age

Most auto parts stores offer free Alternator testing takes 5 mins. if the Alternator is good and will hold a charge,then your problem sounds as if it is a spark plug/ fuel mixture issue,,check plugs and plug wires.

I had a Nissan doing this to me a little while ago, but couldn't figure out the problem. A couple weeks later, the lady told me she took the car to a shop and they replaced the crank and cam sensors. My bet is that it was the crank sensor.

so put some gas in if you think its out. An oxygen sensor inst going to keep it from starting.

mcdevito75 here, The temperature riseing to max the cooling off fast, could be a stuck thermostat of the fan switch for the radiator could be faulty. The hard start after a few hours could be a dirty gas filter. Bset Bet, have your local auto repair shop have a llok.

for one thing you are dfinetly flooding that beautiful engine which can lead to more starting problems STOP IT all you need to do is make sure you have a good battery and alternator and starter by getting all three tested free at auto zone this will solve your problems

Sounds like you have a bad O2 sensor - typically what happens is the sensor will go into closed loop and stay there and once it cools down will open up and be able to start again - your car has two O2 sensors, it is best to replace them both - bet you notice your car getting crappy fuel mileage too. hopefully this helps you, as this is the most common problem - Also, clean your Mass Airflow Sensor, this is really easy to do and may help as well and should be the first thing you do before throwing a couple hundred dollars into new O2 sensors, use CRC mass airflow sensor cleaner available at auto zone or advance auto for about $10.00 a can, if you are not familiar with where it is located ask the guys at the auto parts store to show you - it takes like 15 minutes to do and requires only a t-20 torx bit - this part needs to be cleaned every 6000 miles.

I would start with the Fuel Pump Relay. Check the Fuel Pump, Fuel Filter and Belt Tension.

HI.. You need to replace the Main relay ( Fuel pump relay)
Is located under the cluster behind the steering colunm.
The original nember is RZ0088,
Is a common problem on no starting or running on honda cars.
To get axcess you need to remove the cruise control computer atached with 2 10m screw.

I hope this information work good for you.
