When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

Check your fuel pressure to ensure proper pressure to the block, also did you replace the fuel filter.

On a side note: 3 things a automobile needs to run

AIR-make sure you have a clean air filter and your MAF (mass air flow sensor is plugged in) if you pulled your breather to innspect anything, there is a possibility that it came unplugged or you unpluged it and forgot to hook it back up, a car wont start without it being plugged in if equiped

SPARK-Make sure your car has juice to the plugs, if the plug doesnt fire the car wont run, if you have to pull each plug and ground them to the engine block to see if they arch. If not trace the problem down (if you changed the fuel pump you have some mechanical skill and should be able to troubleshoot a spark issue)

FUEL-Check for proper pressure, dirty fuel filter(s) and if your system has a return line, make sure your hoses didnt get crossed cause this will damage the engine and regulator.

Hope this helps Thanks for using Fixya.com

I have 2008 GMC sierra 5.3 L with a new fuel pump. And no power to the pump. Any ideas where to look?


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.

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 .

The tank is large & under the car ,under the rear seat
Have to remove the exhaust system & drive shaft

The Fuel Pump Relay --is in the Battery Junction Box (BJB) as well
as the Fuel Pump Motor Diode

There also is a (REM) Rear Electronic Module
I recall that has a variable speed pump regulator
or whatever

There are even more players there as well

Very complicated system ,that you have no way to even

New starter,new alternator,new fuel filter,turns over wont start a little gas in carburator step on gas let off gas turn key starts then runs


check the fuel pump, it sounds like as it sits its losing pressure, when you first turn the key to the on ( not start) do you hear the fuel pump running then shut off? your fuel pump should keep pressure on the line at all times, so if you do hear the pump start it should be a very brief spurt and thats it, you can have the pressure checked at many repair shops for free or low charge,

Check the fuel pressure at the fuel rail on top of the engine it should read a minimum of 30 psi if any lower replace the fuel pump, also if you smell a gas odor and the fuel pressure regulator looks wet with gas replace the pressure regulator before the fuel pump. This sounds like a fuel delivery issue.

Fuel pours into cylinders


very strange and rare problem. something is keping the injectors open instead of pulsing them. The command to ground the injectors comes from the PCM, Powertrain Control Module. It may be a good idea to pick up a used one from a salvage yard. car-part.com is a good place to look. You will need the info off your module to match up.
Do you have 2.0L SPI engine or 2.0L Zetec engine?
Look on the page with the * to find the lowest price part.
aso, check for shorted wire going to injectors
---------------------------------------------

Mechanical Returnless Fuel System The fuel system consists of a fuel tank with reservoir, fuel pump, fuel pressure regulator, fuel filter, fuel supply line, fuel rail, fuel rail pulse damper, fuel injectors, and schrader/pressure test point. Operation of the system is as follows (Figure 62):
  1. The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal.
  1. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM.
  1. The PCM grounds the fuel pump relay, which provides VPWR to the fuel pump.
  1. The inertia fuel shut-off (IFS) switch is used to de-energize the fuel delivery secondary circuit in the event of collision. The IFS switch is a safety device that should only be reset after a thorough inspection of the vehicle (following a collision).
  1. A pressure test point valve (schrader valve) is located on the fuel rail. This is used to measure fuel injector supply pressure for diagnostic procedures and repairs. ON VEHICLES NOT EQUIPPED WITH A SCHRADER VALVE, USE ROTUNDA FUEL PRESSURE TEST KIT #134—R0087 OR EQUIVALENT.
  1. Located on the fuel rail is a pulse damper. The pulse damper reduces fuel system noise caused by the pulsing of the fuel injectors. The vacuum port located on the damper is connected to manifold vacuum to avoid fuel spillage in the event the pulse damper diaphragm were to rupture (the pulse damper should not be confused with a fuel pressure regulator).
  1. The fuel injector is a solenoid-operated valve that meters the fuel flow to each combustion cylinder. The fuel injector is opened and closed a constant number of times per crankshaft revolution. The amount of fuel is controlled by the length of time the fuel injector is held open. The injector is normally closed and is operated by 12 volt VPWR from the power relay. The ground signal is controlled by the PCM.
  1. There are three filtering or screening devices in the fuel delivery system. The intake sock is a fine, nylon mesh screen mounted on the intake side of the fuel pump. There is a fuel filter screen located at the fuel rail side of the fuel injector. The fuel filter assembly is located between the fuel pump and the pressure test point/schrader valve.
  1. The fuel pump (FP) module contains the fuel pump, fuel pressure regulator and the fuel sender assembly. The fuel pressure regulator is attached to the fuel pump in the fuel pump module located in the fuel tank. It regulates fuel pressure supplied to the fuel injectors. The fuel pressure regulator is a diaphragm-operated relief valve. Fuel pressure is established by a spring preload applied to the diaphragm. Excess fuel is bypassed through the regulator and returned to the fuel tank.

  1. The fuel delivery system is enabled during crank or running mode once the PCM receives a crankshaft position (CKP) sensor signal.
  1. The fuel pump logic is defined in the fuel system control strategy and is executed by the PCM.
  1. The PCM commands a duty cycle to the fuel pump driver module (FPDM).
  1. The fuel pump driver module modulates the voltage to the fuel pump (FP) to achieve the proper fuel pressure. Voltage for the fuel pump is supplied by the power relay or FPDM power supply relay. (For additional information on FPDM operation, refer to PCM Outputs—Fuel Pump and PCM Inputs—FPM.)
  1. The fuel rail pressure (FRP) sensor provides the PCM with the current fuel rail pressure. The PCM uses this information to vary the duty cycle output to the FPDM to compensate for varying loads.
  1. The engine fuel temperature (EFT) sensor measures current fuel temperatures in the fuel rail. This information is used to vary the fuel pressure and avoid fuel system vaporization.
