Turned out to be the starter motor. Let the relay click off a second time, and then start the car.

Once you get it running everything is fine.

Car struggling to start diesel. Wear and tear on the piston rings and cylinder walls result in lost combustion. If you listen carefully, some seconds later, you'll hear a click as the glowplug relay finally stops the current. If vehicle had been parked for an extended period or a long time, and the starter cranks.

The problem goes something like this (on a 1969 to 1985 diesel). Function of a glow plug When you turn the key or push a button to start a car, the battery sends electricity to the starter motor which signals the crankshaft to start turning.

The use of glow plugs or block heaters will start the vast majority of diesel engines on a cold day. A few tips on starting a diesel engine on a cold morning: Buying a used diesel car.

It may even start and then quit once or twice. That’s the light that comes on and goes off after a few seconds. Sometimes if the car is left for a full week, it will almost not start.

When you hear that, turn they key off, then back to glowplug position again. The fuel will start to gel and clog at 10 to 15 degrees. The forgoing assumes that, as you say, the battery and starter are f.

Once started and even when it is struggling to start, it throws. The ratio of fuel and air should be proper, otherwise, the mixture will be too rich, which will result in black smoke. When you first notice that your car is struggling to start, you'll want to be proactive about addressing the problem.

As in any machine, there can be many reasons for poor or absent performance. Glow plugs work by heating the internal combustion chamber so that conditions are suitable for. You're having a start up issue related to the fact that the computer does not know if the car is hot or cold.

If you are having issues starting and all the three things above are good you could have gelled fuel. This will clog the tank and fuel filters. Diesel fuel can become gelled when the diesel starts to turn into a solid when the temperature drops.

However, problems often start when the car approaches the 150,000 miles mark. Worn injectors not atomizing correctly. This is where your glow plugs come in.

In this case plunger piston cannot make enough pressure to open the injection. To repair this, drain the old fuel and you may need to flush fuel lines and injectors. As diesel engines age, the fuel injection system can start to “gum up”, and the injector tips begin squirting instead of misting.

These are the main two reasons why your car is not starting when it is cold. I had exactly the same problem this week (on an admittedly old diesel) and my car eventually failed to start at all on tuesday. By saying that the engine won't turn over means that the crankshaft isn't turning, so the other parts won't be able to move to start the car.

Glow plugs and block heaters: If your car is 10 year old or older, check your starter motor. Most common causes of black smoke from diesel engine include:

The engine may also be much noisier than it normally is, sounding more like an aeroplane taking off than a car. Difficult start of the warmed diesel engine as opposed to the easy cold start can be caused by the high pressure fuel pump malfunction connected with the plunger pair wear. The car will start up first time may idle roughly with the needle bouncing for a little while.

And this is where glow plugs come in. A deficient spark plug causes the engine to misfire, making your car jerk when you accelerate. I'll try to zero in on the most common ones for diesel engines.

When you start a diesel car, especially on a cold day, the first part of the ignition process is to allow the glow plugs to heat up the cylinders. If your car refuses to start, there are a few tricks. I had the battery tested and it is fine.

A clogged catalytic converter is another reason why a car jerks while accelerating, as a blockage can disrupt the exhaust system’s airflow. This is even with a relatively new 640cca 64ah battery. Other problem causing factors are a bit more complex but can be easily fixed or avoided.

You can check your injectors, but if the car runs fine i would be surprised if this is your problem. The internal combustion process in diesel cars requires a certain mixture of fuel and air. A diesel engine therefore needs starting assistance.

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. Your engine normally starts just find when hot or when it has only sat for a few hours. Modern diesel cars are great when they are new.

Well, the glowplugs are still heating up even after the light goes out. Black smoke indicates that the fuel is not burned properly. By delaying, there's the risk that the issue will soon worsen to the extent that you can't get your engine to start whatsoever.

If the engine is too cold, there is too much play between piston and cylinder wall. I have a 2007 peugeot 207 1.6 hdi, with 83,000 clocked miles. For the sake of example, let’s say that you bought one with 150,000 miles on the clock, and you are planning to.

Feel free to give diesel and. Only when the engine is sufficiently warm, metals expand enabling the combustion process. Basically, the longer the car sits unused, the more blue smoke it puts out when it starts and also the harder it is to start (cranks slower the longer it is left).

It is very likely your starter motor is not turning quickly enough. Consider these the low hanging fruit. The injection timing can get out of whack.

When fuel warms up, its viscosity decreases and hydraulic losses in clearances increase. Too much compression is lost and the engine cannot start. A common possible cause is stale gasoline or diesel fuel, or a seized fuel pump.

When your diesel is hard to start it's the middle of summer and your diesel engine is having trouble getting started. But after sitting overnight, you find you have to crank and crank until the engine fires.
