Turns out that Hondas are notorious for having starting problems during the summer (sometimes it also happens when you just run them for a short while). I have a 1990 honda civic lx and was having starting problems and noticed that it was mostly during hot days. I got my starter rebuilt but the problem continued. Also I noticed that my car was flashing CODE 16.
The flashing code, together with the starting problems, points to a problem with the MAIN RELAY.
Turn the ignition on and check for codes, pull the carpet back on the passenger side floor and look for the flashing LED, count the flashes--that'll be the code (there's a short pause inbetween codes).
The Main Relay is located under the dash on the driver side, usually on the left hand side, can be up against the left wall, it's a small black unit with a plug. You need to unscrew it from its mounting bracket first. Change the main relay and it should solve your summertime starting problem.

These are the some reasons why a car have problem in starting.
1. bad spark plug
2. bad wires
3. bad rotor
4. bad distributor cap
5. bad ignition coil
6. fuel pump could be malfunctioning
7. fuel filter could be clog
8. fuel accumulator could be faulty already
9. faulty fuel pump relay
10. fuel in the tank could be dirty
11. weak battery
12. dirty or corroded battery terminals
13. bad starter
14. loose wiring connection between battery, starter and alternator
Have these things check with your car, it could be one of this is your car's problem. Hope this might help!

Hot and Cold When your Engine is Hard to Start
In order to surpass this problem and to prevent it as much as possible, learn how to solve it by knowing why it happens.

When a hot engine is hard to start, most of the causes are fuel related problems. Fuel cannot circulate well due to the way in which vapor blocks it. As a result, the engine would not start as easily as it should. In worse cases, it would not start at all. This happens if the engine is extremely hot.

Until after a while the engine was shut off, it would keep on acquiring temperature. The biggest amount of water vapor would be spreading around during this process. It therefore means that during this period, there are higher chances of its obstruction to the engine. So when you are driving in hot weather and you have just turned off the car and you experience difficulty in stating the engine, do not panic. Just wait for a couple of minutes and then start it back.

Because the fuel remains inside the injectors by being under a very intense pressure, engines that are fuel injected do not experience and suffer this problem as much as others do. In this case, fuel injected engines would not become so easily moved by vapors as compared to other engines. From this fact, it can be further deduced that auto mobiles may have different problems in starting their engines.

Another reason of a difficulty in starting a vehicle is the coinciding of the engine's hot temperature to a hot season like the summer. In this scenario, refiners alter from a fuel blend to another. Due to the process where in hot weather causes fuel to evaporate faster, gasoline refiners sometimes alter from a higher hot blooded fuel to a lower one when summer approaches. The fuel could evaporate too much that it would create too much vapor and would eventually inflict the engine. This instance happens when refiners alter back to a higher hot blooded fuel while the engine is still exposed to high temperatures of the summer season.

Now you know why hot engines are hard to start and what to do with it. What about if a cold engine is hard to start?

Difficulty in starting a cold engine is really a problem especially to those living in cold areas. This is experienced due to several reasons, and one of which can be based on the cold effect on liquids evaporation. Less gasoline is evaporated when the engine is cold. This causes the fuel to be more burdensome to burn due to the fact that it is burnt when it is evaporated.

Oil becomes much thicker in cold areas than in hot ones. This is another reason why cold engines are hard to start. Like any other fluids, oil alters its characteristics when it is heated or when it is in a very hot weather. Often times, this causes the oil to have problems at the time it circulates in the engine of the vehicle.

Other car parts that contribute to this problem are the batteries. Under a cold weather, the car batteries sometimes experience problems that consequently affect the engine of the car. When being cold, batteries loose their agility. This is because they do their jobs due to chemical reactions. And when they loose their agility, of course it means that they do not function well. Under these circumstances, the energy of the car is affected and so the engine start is also affected.

Another problem could be the air intake. Like in the case of your Dodge car, the Dodge cold air intake, it might not be functioning well that affects the performance of your engine.

If these problems happen together at the same time, they imply a huge problem in starting the engine.

Spray ether into the engine. Use one that would evaporate quickly and help the engine start. Do this to overcome the problem on the lack of gasoline evaporation. Aside from this, you can also use thin synthetic oils in order to prevent very thick oil that would not circulate well. You if can maintain the car from being isolated from cold, better!

Crank sensor


Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.
This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.
Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.
A Seasonal Problem Hard hard starting tends to be a seasonal problem, but may be worse in the early months of spring when refiners are switching fuel blends. Gasoline refiners produce fuel with a slightly lower volatility rating (called "Reed vapor pressure") during hot summer months because lower volatility fuel is less likely to boil and cause hot starting problems. During the winter, they switch to a higher volatility fuel because it makes cold starting easier. But if you still have "winter" grade fuel in your tank when warm spring weather arrives, you may experience some hot starting problems. The problem will go away, however, as soon as the refiners in your area switch to their summer grade fuel.
Other Causes Hot starting problems can also be caused by cooling problems that allow your engine to run too hot (the pistons swell up and may scuff the cylinder walls), or excessive resistance in the starter motor that causes the engine to crank slowly. A starter "amp draw" test can be used to check the condition of your starter. Also, many starters have small "heat shields" to protect them from heat radiating from nearby exhaust pipes or manifolds. If the shield is missing, the starter may get too hot and bind up.

Will not start in cold weather. Engine will crank and try to start and started all summer but last spring and now that the weather has turned turned cold. It will start first thing in the morning and it...


Get your battery voltage checked.The cold weather will reduce the strength of your battery. The starter solenoid is trying to engage the starter but it doesn't have enough power from the battery to make it happen.If the battery voltage is low then get it recharged .The voltage of fully charged battery will show near to 12 volts.--------------That's it.

What is the condition of the starter ? Is this an engine hard to turn over problem when hot ? If so, the starter might be grounding out, this happens only when the casing is hot.
