For a diesel engine to work correctly, having a working injection pump is a must. This equipment helps to inject the necessary fuel needed into the engine through adequate pumping.
By using the gears or chains, the crankshaft can be activated, which in turn runs the injection pump. CAV is a famous brand whose injection pumps are commonly used and very well known in the market.
Every piece of equipment can run into one problem or another once it gets old. Sometimes, lack of maintenance is also responsible for equipment breaking down. A CAV injection pump can break down as well.
In this article, we will get to know about CAV injection pump troubleshooting and the necessary steps to undertake in such circumstances.
Common Problems with CAV Injection Pumps
Without an injection pump, it is impossible to run an engine. Often, your car does not run smoothly, or you face difficulty with starting the vehicle due to issues with the engine. And behind the malfunctioning of the engine, the role of the injection pump can often be found.
So you need to be aware of the most common types of problems that might occur due to issues with the injection pump.
The main task that is fulfilled by an injection pump is fuelling the engine with diesel or any other fuel. It directly pumps it down to the combustion chamber of the engine, which in turn helps the engine to run smoothly.
Therefore, restructuring and adequately maintaining the injection pump can go a long way in making sure of the engine’s wellbeing.
Without further ado, let’s look at some of the most common problems that you often face but might not realize that a faulty injection pump causes it.
By an engine running unsmooth, we mean that the sudden coughs and bumps that you face while your car is running at speed. This often happens when there is a problem with the injection pump. The problem leads to the engine being deprived of the sufficient amount of fuel it needs to run smoothly.
Sometimes, you might not realize that there is a problem if you drive at a slow speed. This is because the problem shows up mostly when the engine runs at high speed. So make sure to check on this from time to time.
Misfiring of Engine
Often, due to the injection pump malfunctioning, the engine misfires. This means that the engine is not sparking correctly at the right moments, which is causing you to face difficulties while driving.
Now, the problem of misfiring arises when the engine is not receiving the proper amount of fuel it needs to run. Therefore, the injection pump needs to be checked quickly as overlooking this problem further might deteriorate your engine’s wellbeing.
Worn out Engine
Another problem that can be caused due to a lousy injection pump is a fragile engine. Often, a lot of drivers ignore the symptoms that are indicative of a problem with the engine receiving sufficient fuel. As a result, the engine ends up being weak in the long run.
When the engine combusts the fuel, a residue is produced, which the engine needs to get rid of. This is known as exhaust. If it remains inside the engine, the engine might get severely damaged.
When you feel like there is something wrong with your engine, check if the exhaust within the engine is smoky. If so, then it indicates that your injection pumps are dirty, which in turn is causing the problems of the smoky exhaust.
Failing to Start
The most common problem that people face with a faulty injection pump is the difficulty in starting their vehicle. This is caused when the engine does not receive the adequate amount of fuel it needs from the injection pump. When this problem occurs, check your injection pump for any issues.
Solutions for Different Common Problems with CAV Injection Pump
The steps that you can undertake if you run into problems with your CAV injection pump are given below –
Possible Home Remedies for Difficulty in Starting Car
If you cannot start your car, then possibly there is some issue with your injection pump. To solve it, you first need to find out what’s causing it. For example, if the fuel injection pump is not working, replace it, or tune it. If you see the engine is not receiving enough fuel, drain the fuel tank, clean it and then refill it.
Remedies for When the Injection Pump Becomes Too Hot
Usually, an injection pump becomes too hot when it is running very fast. This usually happens when fuel overflows due to which its opening gets blocked. In order to solve this issue, you need to clean up its opening and replace the necessary fittings properly.
Remedies for Weak Engine
When your engine cannot run at its full capacity, there is likely to be a problem with its injection pump. In such cases, check if the injection lines are blocked in any way.
If that is the case, then drill the lines to minimize the block or replace the injection lines with new ones. Sometimes, the injection nozzle can also become defective. In such cases, clean it. And if the problem persists, replace the nozzle.
Visiting a Service Center
An engine is the most fragile part of a car, and an injection pump has a big role in maintaining its health. Therefore, as soon as you detect a problem with your injection pump, it is best to visit a service center. This is because doing it yourself might add to your problems instead of solving it if you are not an expert at this.
The first step to take when you realize something is wrong with your injection pump is to clean it and tune it. If that does not solve your problem, try restructuring it. You can replace it if the other two options don’t solve the problem. And as a last resort, you can visit a service center.
