How to Replace the Fuel Injection Pump

What is the fuel pump and the way does it work?

The fuel pump supplies pressurized gasoline to every of the fuel injectors during a car’s engine. The fuel pump is powered by a compact motor and is found within the vehicle’s gasoline tank. The pressure and output of the pump are controlled by a regulator. Filtration of the fuel occurs either within the fuel tank employing a pickup screen or externally with a replaceable filter mounted within the fuel supply route.

When to think about replacing the fuel pump?

A top-quality, OEM fuel pump can last indefinitely. However, like any electro-mechanical component, a fuel pump will eventually degrade and fail. If it fails to supply adequate pressure or completely quits operating, it’ll be got to get replaced. This failed condition can sometimes be preceded or amid one or more of the subsequent symptoms:

Car won’t start or unexpectedly stalls and won’t re-start. A failed fuel pump may prevent a car from starting or stall it.

Check engine light is on. Sometimes a fuel pump will fail slowly, which means the fuel pressure and volume slowly degrades. the shortage of fuel may end in the engine operating without enough fuel relative to the quantity of air, causing the check engine light to seem.

Whirring noise from the fuel tank. As a fuel pump fails, you’ll notice a whirring or humming noise coming from the fuel tank area, toward the rear of the car. If the noise is from the fuel pump, failure of the pump is usually imminent and you ought to replace the fuel pump at your earliest convenience.

How do mechanics replace the fuel pump?

The fuel pump is tested to make certain it isn’t functioning.

Should the fuel pump be faulty, it’s far away from the tank through an access panel above the tank within the passenger compartment.

When no access panel exists, fuel is first drained from the tank then the fuel tank must be lowered from the vehicle to realize access to the pump.

In all cases, fuel pump supply and return hoses, also as EVAP system hoses, and electrical connections to the pump must be removed.

Once the pump is out, any reusable brackets and devour screens are attached to the new pump, then the new pump is installed.

If the equipment uses an in-line external filter, a filter is usually replaced. All hoses and electrical connections are re-established.

Fuel is added to the tank and therefore the engine is run to check for leaks.

Is it safe to drive with a fuel pump problem?

Usually, it’s still safe to drive, but the pump may cause an overheated engine and converter. Complete fuel pump failure can leave you stranded out on the road, but repeatedly a car won’t start before initially driving.

However, if the fuel pump problem involves leaks of gasoline or vapors, it’s unsafe to continue driving, and will immediately be checked by a professional mechanic.

When replacing the fuel pump confine the mind:

Prior to replacing, the mechanic will power the fuel pump on to confirm that the difficulty may be a failed pump versus a faulty power supply to the pump.

Unless the filter was replaced recently, whenever the fuel pump is replaced a replacement filter should be installed.

When failing before expected, the facility supply should be verified because a drop within the fuel pump circuit can cause overheating.
