There is a much richer fuel mixture during a cold start, the colder the engine the richer the fuel mixture
retarded ignition timing causing the fuel to burn for a longer period of time makes the engine heat up faster
anything that doesn't allow the mixture to be properly metered, like vacuum leaks, bad temperature sensors, or O2 sensors, MAF or MAP sensors, bad EGR valves or PCV valves hoses or tubes,
and or
anything that will cause the fuel mixture not to burn properly, like worn spark plugs, or any other ignition part, wires, cap, rotor, timing, compression, will cause poor start or no start conditions that are worse in lower temperatures,
also low voltage, week battery, slow cranking of the engine can also cause hard to start conditions

My 94 Blazer (125,000 miles) has run great since I bought it 5 years ago but recently developed a problem. When I drive it on warm/hot days, it starts right up when cold but after driving even for a short...


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.

I have trouble starting my van when its is cold. after that its fine. the colder it is the longer it takes to start.


Not an unusual problem.....

Most important- tune-up! Make sure your plugs, distributor cap and rotor (if so equipped), air and fuel filter are OK and have been changed (at minimum) according to your owner's guide.

If your vehicle cranks over slow when cold-starting, consider a new battery. In cold weather, batteries lose efficiency, and older batteries lose more power than new ones.

Next... Gas - the fuel in cold weather states has a formula change in winter months to lower emissions- sometimes going to the next higher grade of fuel (example: from regular to mid-grade) helps.

If you have a garage, keeping the vehicle inside makes a huge difference with cold weather starting.

Keep your fuel tank full. Running the tank down and leaving it near empty most of the time allows condensation, which will result in getting water in your fuel, leading to hard starts and poor performance, and the increased risk of "rusting through" which will cause a leaky fuel tank.

83 Rx7 stalls when cold unless I keep applying pedal pressure


these cars are carburated motors and need around 10 minutes to warm up because they operate at higher temperatures.

2001 chevy silverado 1500 v8 battery drain after sits for 1or2day


, do a simple test on the charging system...check battery voltage. should be 12v or better. start engine & check volts at idle, no accessories on. volts should read 13.5 -14v. Turn on all accessories(including headlamps on high) volts should drop slightly but should not creep down. Definitely not below 12.5. If voltage drops lower than 12.5, the regulator (in the alternator) is not working. either change regulator or change entire alternator. Alternator drive belt should have sufficient tension so that alternator cannot be turned easily by hand. If it can, check belt tensioner.

Won't start


Most vehicles have problems starting when it is cold. Short of installing a block heater, your problem lies in your battery. if it is cold in your area for a few months of the year, my suggestion is to invest in a higher rated CCA battery, and a block heater.

Cold Cranking Amps is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. The higher the CCA rating, the greater the starting power of the battery.

This morning it was -19F here, and my new car gave me a fit starting, so you are not alone. Replace the battery, and pay a little higher premium for CCAs and you should be fine.
Good Luck.

Engine will not idle and run when starting in cold weather


Have a mechanic take a look at your throttle position sensor and engine idle sensor. Make him manually adjust them as opposed to just putting in new ones. It may require that you have to have a higher idle than normal. Your underlying cause is going to be that I am sure you have a lot of miles on your engine.
