If it's fuel injection I don't think it will have a choke. It will have what they call an Idle Air Bypass valve or something of that nature. If you can find it take it off and spay Carb cleaner through it. Be carefull not to get it in your eyes. I'll do some research and see if I can find a photo for you. A lot of the time they get dirty and just need a good cleaning.

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.

Hard starting, rough idle when cold, then smooth running when warm


Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.

When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.

How do you check an automatic choke


It depends on the vehicle. Some or all manufacturers have a specific procedure for testing the choke and all its linkages and controls. But just observing your choke in operation from a cold engine (choke butterfly valve barely open) to a warm engine (choke valve fully open) should give you a good idea of how well it works. The electric assist on chokes is mainly for opening the choke a biy sooner than the mechanical operation of heating the spring inside the black choke housing, causing it to expand and open the choke valve.

1975 Datsun (ie. mechanical fuel pump). Carburettor, electrics (inc. battery all good) fuel strainer all good. On cold start engine needs to be cranked several times. Warm start is invariably immediate. ...


Carburated vehicles ether have an automatic choke, or the very old ones, a hand choke. Yours has an automatic choke. The starting problem likely is a problem with the choke. The problem is almost certainly not the fuel pump.To set the automatic choke, push the accelerator to the floor, and RELEASE. Then start the engine just like you would a fuel injected vehicle. If this doesn't solve the problem, then the automatic choke needs to be repaired.

Worn ignition components or bad fuel system issue. With the vehicles age I would suggest a full tune up as people seem to think Mercedes means all parts last forever.
