Honda Car Forum

I noticed that the car jerks for a while and starts when the wheather becomes hot but would not do so early in the morning when the whether is still cold and after observing this for sometime i want to believe there must be something responsible for it that i have to change.I tried a used cold start switch but no luck.

have your battery tested

check spark plugs .

you need some defrosting device for the fuel system maintaince guider. it costs a lot, around 7000$ but its worth it. you could also try to light a match and place it where you fill the tank from, then run like crazy.

there is something wrong somewhere else

this indicate that either your vehicle is leaking gas when you turn off your car when the weather is hot.on fuel injector system,it could be leaking injectors or cold start valve. OR you have electrical problem such as ignition igniter or ignition control module depending on the year make and model.

Ignition switch is for contact purpose when you turn your car key. It has nothing got to do wheather condition.I suspect your battery could be the culprit. Wheather cold the battery could be dropped to less than 12 V DC or the current in Amphere is not strong enough to crank the car. Send your car to the battery workshop to have a check on the battery control before suspecting anything else. A car battery life will normally last between 1.5 to 2 years. Hope this help.

Be sure to post the year, make and model. I'll assume it's fuel injected.I'd indeed start with the battery. Some places, like Autozone offer free battery testing.If the car is cranking strongly but not starting in cold weather i.e. the battery is fine, then you may need to look at other components.

i think that the most likely problem would be your battery. I would definitely have it checked, also check and see if it is still under warranty, because then you could have it replaced for free.

If a noticeable fuel increase has occurred lately then it is probably the fuel injectors blocked or leaking a very fine mist of fuel when cranking engine, but when engine gets hot it expands slightly stopping the leak if this is the case fix immediately risk of fire extremely high in this condition .check also the whole fuel system and use your nose rather than looking for leaks petrol evaporates almost immediately when in small amounts leaving not much visible trace on surfaces .have someone crank the engine and look and sniff from a fairly safe distance at the engine, whilst they do that about 3-4 times in short bursts otherwise you will paralyse the battery.!!CAUTION!! DO NOT undo fuel injectors or touch them while cranking or running the engine because the petrol is in a highly fast jet it can penetrate your hand (fatal/)in some cases!!!and a fire risk/certainty!
