SOURCE: fuel pump

There are 2 fuel pumps , the primary pump is in the left rear corner of the engine bay (sitting in the drivers seat)there is a fuel filter in this bracket also.The injector pump is situated on the front of the engine block

SOURCE: Low Fuel Pressure on Landrover Freelander TD4

From 53 reg onwards, diesel pump is under R.H. rear wheel arch, hidden by the plastic wheel arch liner. Older versions have combined fuel pump/sender in the tank (under R.H part of rear seat).
You should be able to hear a faint purr from the pump when ignition is turned on but engine not yet running.

SOURCE: I have a 1988 camper it's on a Ford F350 chasse

The catalytic converter may be fried. Very poor design of the restricted exaust ports.
And the fuel pumps are junk straight from the box. Around 94 Ford had to change the design of the fuel pumps.
I am not a mechanic but had the same issues.
I removed the catalytic converter and get the inspection done by a freind.
Your alternative is to change the entire exaust system to say a "Banks". Which is about $3000 for the paRTS.

The problem is the ECU (89661-42xxx). It must be either replaced or repaired. Mine was sent to www.otherdeal.com
and was repaired. Buying a new one was way too unafordable for me (alost $1500 ---USED, NOT EVEN NEW---).

Check for a fuel pressure regulator. If you are testing the pressure at the end of the line, the fuel has already passed through the regulator. I'd be willing to bet the pressure coming from the pump(s) directly is up to snuff.

Fuel control module 2008 escalade and the fuel pump quit working.if I run a hot wire to it it will run but as soon as I remove the hot wire it quits

Fuel Pump Flow Control Module (FPCM) - LMF
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a 25 KHZ PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal. Maximum current supplied to the fuel pump is 15 amps. A liquid fuel pressure sensor provides fuel pressure feedback to the FPCM.
Electronic Returnless Fuel System (ERFS) - LMF
The electronic returnless fuel system is a microprocessor controlled fuel delivery system which transports fuel from the tank to the fuel rails. It functions as an electronic replacement for a traditional, mechanical fuel pressure regulator. A pressure vent valve within the fuel tank provides an added measure of fuel pump flow control module (FPCM). Desired fuel pressure is commanded by the engine control module (ECM), and transmitted to the FPCM via a GMLAN serial data message. A liquid fuel pressure sensor provides the feedback the FPCM requires for Closed Loop fuel pressure control.
If your vehicle has this system check it for DTC'S - diagnostic trouble codes . Will take guess work out of it .

DTC P023F: Fuel Pump Control Circuit
The engine control module (ECM) supplies voltage to the fuel pump flow control module (FPCM) when the ECM detects that the ignition is on. The voltage from the ECM to the FPCM remains active for 2 seconds, unless the engine is in crank or run. While this voltage is being received, the FPCM supplies a varying voltage to the fuel tank pump module in order to maintain the desired fuel rail pressure.

Where is fuel pump relay on 2009 gmc acadia


Your vehicle has no fuel pump relay . Has a fuel pump flow control module .
Fuel Pump Flow Control Module (FPCM)
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal.
Plus it has two fuel pumps !
The high pressure fuel pump (9) is a mechanical one cylinder design driven by an eccentric on the exhaust camshaft (1) of bank 2. High pressure fuel is regulated by the fuel rail pressure (FRP) regulator, which is a part of the high pressure fuel pump. The FRP regulator is a magnetic actuator which controls the inlet valve of the high pressure pump. The ECM provides battery voltage on the actuator high circuit and ground on the actuator low reference circuit. Both circuits are controlled by the ECM. When the ECM deactivates the FRP regulator, both circuits are disabled and the inlet valve is held open with spring pressure. When the ECM activates the FRP regulator, the low circuit driver connects the low reference circuit to ground and the high circuit driver pulse-width modulates (PWM) the high circuit. The ECM uses the camshaft and crankshaft position sensor inputs to synchronize the FRP regulator with the position of the eccentric on the camshaft. The ECM regulates fuel pressure by adjusting the portion of each pump stroke that provides fuel to the rail. The high pressure fuel pump also contains an integrated pressure relief valve.
Your best bet is have it towed to the dealer , you don't want to mess with the high pressure pump .

2001 td4 its ticking over between 500 an 800 rpm and seems to using more fuel than it as befour.normal driving seems fine .if driven in first gear at one speed yet again its up and down thanks phil.


The poor performance of the car makes these faults to come up and undermine the working of the engine. Check on the fuel filter will confirm this as it will be seen, if so remove and clean tank and change the filter. We then come to the fuel pump and pressure is determined in this section. You need to have the pump calibrated if the pressure at the injector is low. Also check compression of engine if there is imbalance on the engine or reduced power.

Thank you for using Fixya

Freelander TD4 (2004) is loosing power when accelarating and black smoke coming from exhaust. What is problem?


does the engine management light come on and does it go into limp mode, if so mine has just done the same, high pressure fuel pump is on its way out ,had a new one fitted no problem.

Diesel filter


The fuel filter is under the bonnet, on the left side behind the engine bay fuse box. Adjacent to the 2nd low pressure fuel pump.
