If it under 12.3 v, then get a new one. Was starting good and running fine. If it is an efi (which just about every car has been for a long time) car maybe the car has a bad 02 sensor, if it is a very old car it could be a carburettor car with a carburettor problem.

If your car is slow to start it is generally a sign of an underlying problem. You should also watch the multimeter while someone else cranks the car and see that the voltage doesn't drop below about 10 volts while cranking. There can be many reasons for a vehicle not starting in cold weather and some can be as simple as a weak battery that needs replacing.

Why your car starts more slowly in the cold. Goes up to about 1100 rpms and as it warms comes down to 800 where set. Do you have any ideas?

Other problem causing factors are a bit more complex but can be easily fixed or avoided. If the click is missing, the likely problem is the solenoid. Excess carbon around glow plugs or spark plugs.

Once you get it running everything is fine. It has an electric pump and that appears to be working as it runs fine after starting but it. The problem goes something like this (on a 1969 to 1985 diesel).

You should ensure you understand all of the causes, educate yourself on the symptoms, and take action before more damage develops. The ecu computer is the brain of the operation and it determines how much fuel the engine needs by receiving readings from various sensors like oxygen (o2), coolant. There are cases where this is related to the starter, the battery, or even certain parts of the engine.

Lots of vacum hoses replaced on. But after sitting overnight, you find you have to crank and crank until the engine fires. This is a warning sign that if these filters remain dirty or clogged, things will begin to get worse or break down.

Diesel and gas engines run very similar fuelling systems, the difference being diesel systems run much greater fuel pressures and have more control over the fuel quantity delivered. I tend to run errands on the weekends, so this is when i realized something was wrong. If those things are ok, do a voltage drop test.

This burns down to answering the question of the role of these important installed parts in your car. The check engine light goes on and it will. This issue only when starting cold seems more likely to be lack of pre heat where ever that engine has it.

Usually, when a car struggles to run in damp weather, the problem is with the ignition system. If that is the case you can try replacing the wires or cleaning the connections. Once the engine is running at speed, the fuel pressure is maintained with no problems.

Sometimes after it dies, if you try again it can start straight away, or you can be waiting for half an hour before you can start it. When it's cold out, your car will start slower than it normally would. As a fuel pump ages the pressure provided can be less that adequate to run the engine correctly.

Recently problem started,, would not start on several. Your ecu should throw a check engine light if there is no signal from the crankshaft or camshaft position sensors. Change fuel / diesel purge.

A symptom of starving the car for fuel is a car that runs correctly at idle and low load, but falls flat on its face as you ask for more power (when climbing a hill, for instance). When you insert the key and turn it into the on position, the accessories might not power on. On the other hand, if you hear a click but no fuel is pushed through the injector lines, and nothing is clogging the lines, it's.
