SOURCE: trying to locate fuel pump relay for 1991 corvette- coupe

The fuel pump relay in the 1991 corvette is located under the IP on the pass side.
Open pass door, unscrew two screws under the glovebox (you will be upside down in the car), take off the fuse panel, unscrew third screw to plastic plate underneath glovebox, pull away carpet (velcro), pull down plastic plate (watch out for the wiring to the lamp), then under the glovebox you will find a number of fuses and relays if you dive in under there DEEP, prob 4 or 5 in a row, not really sure wich one, but one in the middle is the fuel relay, and they are the same (interchangable).
Take a look at --the12volt.com/relays/relays.asp--
It´s those relays we are talking about.

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.

2004 Chevrolet trail blaser shut off switch location


If your talking about the fuel pump, there is no shut-off switch. If your sure it is the fuel pump, check the fuel pump wiring for voltage and ground, engine cranking. Gray wire is voltage, black is ground. The pcm B fuse is in underhood fuse block. If good voltage and ground at the fuel pump with no fuel pump action or fuel pressure, suspect the fuel pump.

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.

Fuel pump relay secondary circuit - high voltage


Here is the definition for the code.
Test procedures are a little different depending on the make and model.

P0232 Description The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump. The ECM enables the fuel pump relay as long as the engine is cranking or running, and crankshaft reference pulses are received. If no crankshaft reference pulses are received, the ECM de-energizes the fuel pump relay after 2 seconds. The ECM monitors the voltage on the fuel pump relay control circuit.

No voltage to electric fuel pump relay?


voltage comes from fuse box, should have a fuel pump fuse, check for blown fuse, if not try jumping a fused wire from 12 volts to relay and see if fuel pump runs, hope this helps ?

2000 buick regal. Losing fuel pump voltage


http://www.bbbind.com/free_tsb.html free wiring diagrams ! Enter vehicle info. year , make , model an engine size . Under system click on engine ,then under subsystem click on fuel controls . Then click the search button , then click blue link .The 7th diagram down shows two fuel pump relays , This I have not seen before ! One is speed cont. relay an the other is just fuel pump relay ? The speed control one has a resistor in the electrical circuit . That is way your droping voltage .
Fuel Pump Electrical Circuit Diagnosis (VIN K)
Fuel Pump Electrical Circuit Diagnosis (VIN 1)

The PCM alters fuel pump speed by energizing the fuel pump speed control relay. Under normal conditions, the fuel pump speed control relay is energized. The applied voltage to the fuel pump is controlled by a resistor assembly. When higher fuel volume is required due to increased engine load, MAP sensor value over 90 kPa the PCM de-energizes the fuel pump speed control relay circuit. The increased voltage to the in-tank fuel pump allows a higher volume of fuel to be delivered to the fuel rail. The PCM also compensates for low system voltage by energizing the fuel pump speed control relay.

Have it check for codes !

Secondary fuel pump is going out what do i have to fix


Your 2000 Ford. only has one fuel pump, no secondary, if no fuel pump pressure, check fuse, if fuse good, check voltage at fuel pump connector, fuel pump sit in gas tank, check voltage there, will only have voltage for 3 -5 seconds, every time the key is cycle, from on to off, if you have voltage there, bad fuel pump, fuel tank will have to come off, to replace fuel pump.

2004 Sunfire Problem starting and shutting down on occasion


I'd want to check voltage and ground for fuel pump relay. The load side of relay is the line with arrowhead, when relay is energized that line with arrowhead moves to other terminal and sends voltage to fuel pump on gray wire. The control side of relay is that coil symbol, it has to have voltage and ground, the voltage comes from pcm, the ground is a chassis ground. The voltage for load side of relay is fuse protected, fp/inj fuse. fuel pump-mo2osvehtzbwzhstuaetpz2s-2-0.jpg
