Question about 1995 Ford Taurus

1 Answer

Fuel pump not firing.

Hello,
I'm having trouble with my fuel pump not triggering. Here's what I've done so far:

Replaced:
Inertia Switch
PCM
CCRM
Fuel Pump and housing (3 times)

I tested all wires leading from each device and their grounds. All of them tested good. If I hotwire the pump from any position (from the PCM, CCRM and so on) the pump activates, so I know that the wires and pump are good. In the wire diagram, I see a "PCM relay", but I have no idea where it is on the car. Can anyone help?
Thanks!

2005 ford focus, the car will start and run for a few seconds then stop. The fuel pump does not come on


Are you missing anything else?
Engine cranking, do you have spark at the plugs and fuel injector pulse? The reason I ask, if your missing all three, have to check for rpm signal, comes from crank sensor.
As far as just the fuel pump, could be the pump--voltage and or ground circuit--could be problem with inertia switch--fuse.
Any applicable trouble codes? To check codes, yourself, at the least, you need an obd2 code reader.
I don't think it is your security system, my info says your security system will disable starter motor among other components. Make sure battery has a full charge.

Where is the reset button on 2002 windstar se ccrm


Your van doesn't have a ccrm. The fuel pump is controlled by the ECM/PCM. You do have fuel pump relay though. The ECM grounds the fuel circuit.

New fuel pump, ccrm and fuel filter and still blowing 20 amp fuel pump fuse


If the components are all good, then check wiring connectors and wiring circuits, it appears the problem is after the ccrm. wiring from ccrm to fuel pump. For testing you should be able to use jumper wire with inline 20 amp fuse, from voltage to fuel pump connector, to see if it will run w/o blowing the fuse. As you can see from ccrm to inertia switch there are two connectors. From inertia switch to fuel pump, one connector. There are many ways to test. With connectors unplugged, you could use a test lite connected to battery voltage, touch correct wire terminal, if lite comes on, that circuit is going to ground, somewhere.
See that one wire that goes down, wire circuit from ccrm to inertia switch, that wire goes to pcm, I believe it to a monitor circuit, the pcm monitors the voltage on that circuit.

1989 f-250 inertia fuel shut-off switch switch location


This should be in the owner's manual. I found the below on autozone.com, their repair help location:
An inertia switch is used as a safety device in the fuel system. The inertia switch is located in the cab, generally under the dashboard on the right side. It is designed to open the fuel pump power circuit in the event of a collision. The switch is reset by pushing each of 2 buttons on the switch simultaneously (some models use switches with only one reset button). The inertia switch should not be reset until the fuel system has been inspected for damage or leaks.
When the ignition switch is ON , it turns the EEC power relay ON . The EEC power relay provides power to the powertrain control module (PCM) and the control side of the fuel pump relay. Power for the fuel pump(s) is supplied through a fuse link or high current fuse attached to the starter solenoid (battery side). From the fuse link or high current fuse, current flows through the fuel pump relay and inertia switch to the fuel pump(s). The fuel pump relay is controlled by the PCM.
When the ignition switch is turned ON , the fuel pump(s) will operate. If the ignition switch is not turned to the START position the PCM will shut the fuel pump(s) OFF after 1 second. The PCM will operate the fuel pump(s) operate the fuel pump(s) when the ignition switch is turn to START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump(s) unless the engine stops, drops below 120 rpm or the inertia switch is tripped.

Open circuit to fuel pump


There is a 30 amp fuse in the underwood fuse block that is for the PCM/FUEL PUMP. It feeds power to the ccrm (constant control module relay). If there is no power to the inertia switch that is the first thing I would look at. It is the part located under the upper radiator support ne'er the battery.

94 taurus, new fuel pump and pcm fan fuel module. car will not start and not getting gas to front. if we put a jumper on wire's at pump car starts and runs great


In the front passenger side corner of the engine compartment is a black box called the CCRM. Your fuel pump relay is inside this box. There is a 30 amp fuse somewhere near the box on a yellow wire that goes to the box. Check the yellow wire at the CCRM connector for power. If no power, find the fuse and replace it. If it burns again, check the wiring at the inertia switch--I had a customer last week that had a short at the inertia switch that was blowing the fuse. If the fuse is good and there is power to the CCRM, try jumping the pump from the battery positive to the CCRM connector pink wire/black stripe. If this turns the pump on, replace the CCRM. If this doesn't turn on the pump, check the inertia switch and wiring to the pump, including the ground wire. Please let me know if you have questions, and thanks for using FixYa.

Car will turn over but won't start. Through the


No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

No fuel to the rail. New pump,filter,control module over radiator(2).checked inertia switch. if wire to inertia switch is same color code as wire leaving ECM then no power leaves ECM when switch is...


It helps if you tell what year,model, engine you are working on. Is power at the Inertia Switch? The power comes from the FUEL PUMP RELAY, the ECM only grounds the relay to turn it on. but not knowing what you are working on, thats all the info I have .
