What are the symptoms of a bad Ficm?
What a Failing FICM Looks and Sounds Like. When you aren’t getting 48-volts to the injector coils you get: hard starts, rough idle, loss of power, poor drivability, and excessive smoke out the tailpipe—and in cold weather each of those symptoms will be amplified.
Does the Ficm control the fuel pump?
The FICM provides a feedback signal to the PCM indicating when the FICM is providing control signals to the injector (fueling) (via CAN2 link and *FICMM signal). The FICM will cycle through the injector outputs when the key is placed in the ON position.
What does the Ficm do?
The Fuel Injection Control Module (FICM) sends an electrical impulse to the injector, to deliver the correct amount of fuel to the engine cylinder at the precise moment it’s needed. It’s vitally important to the engine’s performance and fuel economy.
What causes no Ficm sync?
If there is no FICM SYNC while cranking the engine, then the problem may be your CMP/CKP. The FICM SYNC circuit relays information from the PCM to the FICM. FICM SYNC occurs through two circuits between the FICM and PCM. Check wiring harness to the CMP and CKP.
Will a bad Ficm throw a code?
Often a bad FICM will throw injector misfire codes or even PCM error codes.
Will a bad Ficm cause white smoke?
If after a long cranking with no start you get a lot of white smoke (raw unburnt fuel) out the exhaust, the problem is in the glow plug system. If you do not get any smoke, the problem is probably in the FICM.
How do you test a Ficm harness?
On the four pin ficm, if you put the + post of your multimeter on the bottom pin closest to the driver side and the negative on the – batter post that will give you what the ficm is putting out. if you move your + post to the pin above that one, it will give you the voltage going into the ficm.
Where is the PCM on a 6.0 Powerstroke?
The PCM is mounted to the driver side fender and it will become accessible with the battery completely removed.
How do I check my Ficm?
You can connect a scan tool that will read FICM voltage. You should have a minimum of 45 volts to be within specification with the ignition key in the RUN position, cranking and engine running. Any voltage reading below 45 volts indicates a bad FICM and will need to be replaced.
Can low fuel pressure cause white smoke?
injector pump timing is the most common cause of white smoke. White smoke will result from incomplete combustion if the fuel delivery is delayed or the pressure is decreased. A worn out timing gear can cause the incorrect timing.
Why does my 6.0 Powerstroke smoke white?
Your 6.0 Powerstroke creating white smoke on startup indicates potential unburned fuel due to stiction, which is sticky residue. If your injector has stiction inside, this may result in an issue where your engine’s combustion temperatures are too low to burn off your fuel, causing white smoke.
Can a bad Ficm cause a misfire?
Why is the FICM important to the engine?
The Fuel Injection Control Module (FICM) sends an electrical impulse to the injector, to deliver the correct amount of fuel to the engine cylinder at the precise moment it’s needed. It’s vitally important to the engine’s performance and fuel economy.
How to tell what type of FICM I have?
4 The cover plate is removed from the top of the FICM. Normally, the cover is removed for under-hood testing; we recommend replacing it before removing the FICM in order to prevent damage. 5 With the cover window removed, you will see either four or seven pins. This tells you which type of FICM you have.
How does Fuel Injection Control Module ( FICM ) work?
SAVE TIME, EFFORT AND MONEY WITH A PRE-PROGRAMMED FICM. The Fuel Injection Control Module (FICM) sends an electrical impulse to the injector, to deliver the correct amount of fuel to the engine cylinder at the precise moment it’s needed.
How does the FICM work on a Ford 6.0L diesel?
Ford 6.0L Diesel FICM Repair and Operation. The FICM uses a series of internal capacitors to turn the vehicle voltage (12-14.5 volts) into the 48-volt supply. If the voltage drops below 48 volts, the oil flow cannot be properly regulated and will result in improperly functioning fuel injectors and potential damage.
