Make sure the choke linkage is opening the choke far enough. These cars need major fuel richening for cold start.

SOURCE: most of the time it is difficult to start cold,

It is very p0ossible that the fuel system is a little clogged. It happens to all cars eventually especially if you use the cheaper fuels like supermarkets etc.

Anyway, you can try a decent Injector Cleaner and even change the oil but again use a decent Engine Flush. The stuff I use on my own and friends motors is Injection-Correction.co.uk. You can buy it online and it works a treat. Same stuff the prestige garages use...

Usually a dose of this stuff will give the fuel system a good clear out and make it alot easier to start when cold. Starting issues are usueally fuel related or electrical but by the sound of yours it is purely fuel related. Try it out and reap thebenefits.....

There is leak in the fuel system and air is coming in somwhere. Maybe the hoses with the injectors are leak.

SOURCE: F250 hard to start once warmed up.

You may have a CTS (Coolant Temperature Sensor) problem. If the coolant level is low the CTS could be sending a false signal to the ECM or the CTS may be faulty. The CTS must be in coolant to provide an accurate signal to the ECM and if the coolant level is low then the ECM thinks the engine is cold and therefore provides a rich air/fuel mixture. This, in turn could be the cause hard start (evident by black smoke from the exhaust), and could be the reason the vehicle failed the emission test.

My 1969 GTO takes forever to start in cold weather, once it catches and warms up it runs fine


Assuming the engine is in good shape and not in need of a major tune-up, check your carburetor choke. It's not closing when cold. Clean and adjust.

Get a service manual and follow the instructions. Far too complicated to cover here.

Also, make sure you know how to properly SET the choke on a cold start. Slowly push the gas pedal to the floor and let up. Start engine without touching gas. If it's REALLY cold, like 0 degrees, you can hold the pedal halfway down while starting, after setting the choke.

Put new battery in car. Now it is hard to start. Replaced fuel filter no help. What could the problem be? Engine cranks ok. Seems like fuel not getting to engine. Seems to run fine after it is started....


fuel pump is in the tank but don't think that it is the problem if it runs fine after started. sounds like a cold start problem alot of these vehicle have what they call a cold start injector that supplies the initial fuel to get the car started and then the regular injectors do the rest have this checked and make sure it is working properly.

1980 VW rabbit, manual/fuel injection: I am


it starts from cold because the auto choke is on ,allowing a richer mixture ,try removing the sender unit in the tank and seeing if the connection from the pump to the outlet connection is ok or leaking causing a loss of fuel pressure

It cranks, but it does not run


Have you check the plugs, cables, cap/rotor ?

One thing you can try since it starts good in warm weather, is to ,on a cold morning, take a hair dryer and warm up the suspect part to warm weather condition. Then try and start the car. If it start ok you have probably found the weak part.
