BMW Mechanical Fuel Injection
BMW mechanical fuel injection systems were popular in their vehicles from the 1960s through the early 1980s. These systems were praised for their precise fuel delivery and strong performance, but they also had some common issues that owners complained about. Some of the most common complaints included hard starting, rough idling, and poor fuel economy. These issues were often caused by faulty components, such as injectors, fuel pumps, and pressure regulators. Despite these issues, BMW mechanical fuel injection systems remain a popular choice among enthusiasts and collectors, and many owners still appreciate their performance and reliability.
However, like any mechanical system, BMW mechanical fuel injection systems had their fair share of problems. Here are some common issues that owners of these vehicles may have experienced:
The mechanical fuel injection system uses high-pressure fuel lines to deliver fuel to the injectors. Over time, these lines can develop leaks, causing fuel to leak out and potentially create a fire hazard.
The injectors in the mechanical fuel injection system are prone to clogging due to dirt and debris in the fuel. This can cause the engine to run poorly or not start at all.
The throttle linkage in the mechanical fuel injection system can become stuck or frozen, causing the engine to idle at high RPMs or not idle at all.
The fuel pump in the mechanical fuel injection system can fail, causing a loss of fuel pressure and potentially stalling the engine.
The mechanical fuel injection system relies on a precise fuel pressure to operate correctly. If the fuel pressure is incorrect, the engine may run poorly or not start at all.
Overall, BMW mechanical fuel injection systems were well-designed for their time but can be prone to issues due to their age and complexity. Regular maintenance and inspection can help prevent these issues from occurring.
The cost of replacing the mechanical fuel injection system on a BMW can vary depending on the specific model, the extent of the damage, and where you take your car for repairs. However, in general, the cost of replacing a mechanical fuel injection system can be quite high, as it is a complex and labor-intensive process.
To give you a rough estimate, the cost of a new mechanical fuel injection system for a BMW can range anywhere from $1,000 to $4,000, depending on the make and model of your car. However, this is just the cost of the parts, and you will also need to factor in the cost of labor, which can range from $500 to $1,500 or more depending on the complexity of the repair.
Keep in mind that these are just rough estimates, and the actual cost of replacing your BMW's mechanical fuel injection system may vary depending on a number of factors. It's best to get a detailed estimate from a trusted mechanic or BMW dealership to get a better idea of the cost involved.
