If the exhaust pipe or any of its filters were to get clogged, it would weaken the functionality of the engine by reducing its power and making the vehicle drive slow when trying to accelerate. Stuck brakes. Suppose the intake and exhaust valves open too early or too late. By doing so, the impurities will not be there when the fuel pump sends gasoline into the car engine. He has been working as a car mechanic for over 10 years, and the majority of them specialized in advanced car diagnostics and troubleshooting. Always try to fix the acceleration issues. The fuel pump delivers fuel at the right pressure to meet the engines demands for excellent performance. When these coils arent working correctly, you could notice hesitations, poor idling, and acceleration problems. If the gasoline inside the fuel filter appears dirty or clogged, then it is likely that the filter is clogged and needs to be replaced.Another way to check if the fuel filter is clogged is to check the fuel pressure. Overstretched Timing Belt: If the timing belt is worn, it can cause a rattling noise.

At that moment, the normal light and several other lights appear on the dashboard but the engine doesn't run at all. Replacing a blown fuse or fuel pump relay is considerably cheaper than replacing the fuel pump, which costs around $500 with labor and parts. You'll notice the gauge jumps as soon as you prime the engine. After the ignition coil sends an electrical signal to the spark plugs, they transmit that signal to the combustion chamber so that its air & fuel mixture can be ignited by an electric spark. Over time, your fuel injectors can get dirty, preventing fuel from flowing into your engine at the optimal rates.
