If you've been having problems starting your car, then a bad fuel pump might be to blame. But a good mechanic can help you figure out what's wrong, and fix the problem.

How to Start a Car With a Bad Fuel Pump

A fuel pump is located under the hood of your vehicle, directly beneath the fuel tank. It's designed to force gas from the tank into the fuel line and then into your engine.

It also has a built-in filter that prevents dirt, debris, and other particles from entering your car's engine. Over time, this filter can become clogged, which can restrict the flow of fuel to your engine.

When the filter gets clogged, it causes the pump to not pump enough fuel into your car's engine. This leads to poor fuel efficiency and performance issues.

The most obvious symptom of a bad fuel pump is an engine that won't start. This usually happens when the fuel pump fails to hold positive pressure on the fuel line while the engine is off.

Stalls when accelerating or driving uphill are other signs that your fuel pump is on the fritz. This is because your engine needs more gas than usual to run when you're accelerating or driving uphill, and the pump can't keep up with that demand.

Fortunately, there are some temporary solutions you can try before spending money on a new fuel pump. You can apply external pressure to the fuel line, or you can use a hand pump. But these methods may not always work. If you're still having trouble, then it's best to get your car to the nearest garage for a full diagnosis.
