Hard starting in vehicles:A failing fuel pump can be a major cause of hard start problems on the engines. A fuel pump is designed to deliver gas from the tank into the engine, typically at pressure. Even though the fuel pump is not working, they may still maintain adequate pressure to begin which could be what you are hearing similar to an almost starting condition. Information from the Automotive Repair Associate suggests that about 25 percent of hard-starting complaints are blamed on a faulty auto fuel pump.
Most fuel pumps operate at a pressure of 30 to 60 psi. If the pressure drops below this range, however — when a pump is beginning to fail or during long periods of storage — your engine can struggle to start. Worn pump components may reduce fuel pressure to such a degree that an engine will not start. 20 psi is what it takes for most cars in order to take-off without any problem, and if your machine grabs the ignition up as well as running you do have defective or problematic gas control gear. This is especially common in high mileage vehicles, where the fuel pump efficiency drops also over time.
Replacing a faulty fuel pump, costs about $400 to $800 in total depending on the car model and labor charge. That cost is for the fuel pump by itself, and not including extra parts such as their in-line fuel filter. In the US, a 2019 study by National Automotive Dealers Association largely estimated $600 as average cost to replace fuel pump.
Mechanics usually do diagnostic tests to check the fuel pressure if hard-starting problems are involved. If the pressure falls dramatically from what is expected measured against manufacturer specifications, that would indicate an issue with your fuel pump. An expert automotive repair specialist named, John Smith said "a decrease in fuel energy is oftentimes one of the earliest warnings you need a new car's gasoline pump mainly because it impacts immediately with the capacity to get started on your motor vehicle."
In the world of automotive repair, one such example involved a 2021 recall by a major auto manufacturer for its vehicles having defective fuel pumps that were leading to intermittent no-start conditions. Smelling gasoline in F-150s is so ubiquitous — the recall covers more than 100,000 vehicles.
