There are three common signs of a failing/malfunctioning Freelander fuel pump, and in fact any vehicles fuel pump, these are:
1. The Engine Sputters at High Speed.
The most common early sign of a problem with a fuel pump comes when driving a vehicle at a consistent high speed. While traveling down the road the car will run well for about 10 miles and then begin to jerk around, or sputter, for a mile or two before returning to normal.
Many people will mistake this problem for simple “Dirty” fuel or something similarly fuel related. While that could be the problem, it's not uncommon for a fatigued pump to sputter as it struggles to supply fuel in a constant stream at the correct pressure.
2. Vehicle losing power while Accelerating
Losing power feels very similar to the first symptom, however, instead of experiencing a sputtering from the engine while driving, you will experience it while accelerating from a stop. Usually you'll find your vehicle will initially move before making noises and jerking around as if it was about to stall, only to then continue accelerating smoothly.
The process of acceleration creates an increased demand for fuel by the engine. A malfunctioning pump cannot maintain the required pressure to deliver this fuel in a steady manner, thereby causing the engine to improperly mix fuel and air and lose power. Once pressure is restored, the engine is able to run smoothly and the car takes off.
3. Vehicle surging
The opposite effect of the above symptoms, surging, can also be a sign of a malfunctioning fuel pump. A car that surges will be moving along normally at a consistent speed, then, with no driver interaction, will pick up and “surge” forward as if the accelerator had been depressed.
Surging is created by normal wear and tear of the pump as the pump develops inconsistencies within the motor. This creates a situation where the pump cannot take enough electricity to maintain the pressure needed for steady speeds and may surge or jump forward with a sudden increase in pressure.
So if you have one or more of these symptoms check your fuel pump, and remember, depending on which model of Freelander you have, you could have more than one pump, a high pressure and a low pressure fuel pump, so you will need to check both of these.
