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


Ran a hot wire to what fuel pump or the control module ? Which of these is yours ?

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 P0191: Fuel Rail Pressure (FRP) Sensor Performance
DTC P0192: Fuel Rail Pressure (FRP) Sensor Circuit Low Voltage
DTC P0193: Fuel Rail Pressure (FRP) Sensor Circuit High Voltage
DTC P0230: Fuel Pump Relay Control Circuit
DTC P0231: Fuel Pump Control Circuit Low Voltage
DTC P0232: Fuel Pump Control Circuit High Voltage
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.

The low beams the windshield wipers rear windshield wipers quit working all the fuses seem to be good everything seems to be proper what's the problem


Well Chuck it depends on the make , model an year vehicle you have ! You would need to look at a wiring diagram to see if these thing's have anything in common . Maybe a electronic control module controls them ! GM vehicles use the BCM - body control module to control these thing's in some vehicles , Ford uses The GEM - generic electronic module or SJB - smart junction box an Chrysler has there modules too ! You can go to www.bbind.com for free wiring diagrams ! click on technical information then TSB'S wiring diagrams ! Good luck

How to set timing for 2001 f150 4.6l V8. Daigram if possible. Thank you, Robert.


The ignition timing is controlled by the PCM (Powertrain Control Module) and cannot be manually adjusted. The valve timing is a function of the timing chain and sprockets, again normally this has a fixed value. If the timing chain has stretched out of spec this could cause the timing to be off, typically it would be a minor deviation though.

My 2007 Dodge cummins 6.7 is telling me to perform service and the catalyst is full. How do I fix this problem myself?


Intervention Regeneration Strategy - EVIC
Message Process Flow (Catalyst Full Message)
(6.7L Diesel Engines Only)

Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards, resulting in the
lowest emitting diesel engine ever produced.
To achieve these emission standards your vehicle is
equipped with state of the art engine and exhaust system.
The engine and exhaust aftertreatment system work
together to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seamlessly integrated
into your vehicle and managed by the Cummins
6.7L engine Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust system's
catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance required
on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

Perform Service
The 6.7L Cummins engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR Valve and a EGR Cooler.
This system filters and recycles gasses produced in the
crankcase during the normal combustion process. Perform
Service will be displayed on the overhead console of
your vehicle if the CCV filter, EGR Valve and EGR Cooler
is due for required maintenance. The CCV filter is located
on the top of the engine valve cover. For additional
information, see your local authorized dealer.
Catalyst Full See Owner Manual
Catalyst Full See Owner Manual will be displayed on the
overhead console of your vehicle if the exhaust particulate
filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your Cummins engine and exhaust
aftertreatment system may never reach the conditions
required to remove the trapped PM, if this occurs Catalyst
Full See Owner Manual will be displayed on the
overhead console in your vehicle. If this message is
displayed you will hear one chime to assist in alerting
you of this condition.
Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.

By simply driving your vehicle at highway speeds for as
little as 45 minutes you can remedy the condition in the
particulate filter system and allow your Cummins engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an extended
period of time after the initial warning notification,
the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.

CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it's capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horsepower
and torque output.
The PCM derates the engine in order to limit the likelihood
of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.

I have no injector pusle on a 1997 chevy blazer ,my question is does it get its injector pulse from the control module?


The ECM or electronic control module does fire the injectors, however, the injector pulse that the control module uses to fire the injectors is generated from the igniton module inside of the distributor and then the injector pulse is processed through the control module.

Most likely the ignition module that is inside of the distributor is faulty, or there is a damaged or grounded wire between the control module and the control unit. If there is no problem to be found with the ignition module inside of the distributor or with the wiring between the control module and the ignition module inside of the distributor, then the problem will be with the electronic control module itself. Also, check all of the fuses to the ECM.

Let me know if you require any further assistance.

high voltage is an indication something is not plugged in or plugged in wrong. You will need to test the harness to see if the required voltage supply is present, connector unplugged, if not then your going to have to determine if the siganl comes from the PCM or the fuse block. If its the PCM you may have a bad PCM. Same thing for the ground side. Now if the reference signal and ground are good you could have a sensor issue but I doubt this because you have high voltage on three components. This tells me that three component signals are not getting back to the PCM. This is why it sets the codes. With all the work you just did I suspect you didnt but the wiring back the way it was. Sometimes people take the ground wire off between the engine and and body because its in the way and don't reinstall it. Or don't tighten it enough. With todays electronics there simple mistakes cause unforeseen issues.
