FICM Advice????

03-Blue-Powerstroke · Dec 28, 2011

I have an FICM that does the same thing. It will show 48 volts all day but, the truck does not run right with it. When I switch to my spare it works. Both have the same flash as well.

The buzzing when you turn the key on is what exactly?

its a reminder for morons who think they are gassers dont start them until it stops... those with early strategies that buzz after you turn the truck off are for the hangover crowd..

Why I ask is because the buzzing tone has changed lately

He was talking about the buzzing when you Key on...not off. When you key on, it's the spool valves cycling...which is normal. However, there was a earlier ford flash which cycled the injectors when the truck was turned off to splash oil out of the tops of the injectors...i had this flash at one point.

if the buzzing sound/tone has changed when you key on to cycle the glow plugs before you crank on it....it pretty much means the spool valves are sticking really bad. If that is what yours sounds like...i would hafta bet that your truck starts rough and has a rough idle when cold...right?

Yup it does lol so now would be a good time to send the injectors to Jess?

if you don't drive the truck in the winter...then this would be a good time to pull the injectors and send them to Jesse and have him go through them. Maybe even make them 190's

I know this...

And for the record those with inductive heating strategies will have a progressive buzz sound when it gets colder out. I have an inductive heating flash and it starts slow but gets faster as it nears its buzz cycle. I have brand new injectors, a good ficm, brand new batteries and it still does it, and starts perfectly fine

I started the truck today the buzzing sounds weak, started the truck let it warm up smoking grey blueish smoke burns my eyes.. drove the truck for 25 mins or so and shut it off and the buzzing sounds way stronger. Also when you first start the truck when cold the battery light comes on is that normal? I have brand new batteries and the proper ones this time.

I dont see the 58v mod necassary ive never seen the advantage to them. I run into FICM problems alot in the shop it always seems to be a vibration problem more than anything.

Syn. Valvoline the oil in the truck has 4100 miles on it. I have two bottles of rev x here I will probly change the oil this week.

97strokn&smokn · Jan 2, 2012

Try that before you go buying a new FICM.

I know I haven't tested anything but I'm kinda leaning toward injector stiction is the problem.

07_powerstroke · Jan 3, 2012

I ordered the oil today so I'll have it tomorrow I hope rev x fixes this issue!

so far since i removed my ID moderate tuned FICM with this stock FICM....my truck starts freakin awesome. It always started great with the ID tuned FICM...but something went wierd with it to cause the truck to have really bad idles when cold. Just started the truck up with outside temp being -6* and it fired right up and idled as if it was 80* out...unbelievable. Now i gotta get this thing sent out this spring for the 58v mod and also get it tuned. One thing i noticed with this stock FICM over the ID one...is the noticable reduction in power, throttle response, and smoke. I've been running the ID tuned FICM for over 3 years and was sooo use to the power and throttle reponse...definitly feeling some power loss. A modded/tuned FICM really does wonders. My truck hardly smokes now running a stock FICM with 190cc injectors.

I am hoping when I get my PHP tune on my FICM, it will wake my truck up some and give me some fuel mileage back.

Pizza pig · Jan 3, 2012

im not even surprised! Was the IDP tuned ficm a factory board? even though those things can be reading fine they can still be bad, its awful. Im not even going to waste the time to flash my ficm now and just get a rebuilt unit and have it tuned at the same time.

Good to hear its working well for you!
