awesome post!

 

Thanks very much, but we're not doing anything special over here - just taking care of folks the way that we would want to be taken care of.

To the other poster's note that some do not actually fix these modules at all, it's amazing to me how many modules supposedly carrying a 'lifetime' warranty we see in from other shops. Not much to do about that, I suppose, but I welcome any ideas. I hate seeing people get left holding the bag.

 

Reading your posts and finding them helpful.
while testing the FICM I get 19v for a few seconds then goes to 48v
Is this a common reading/ cranking getting 48v
I can not start my 2003 6.0 L and get black smoke while cranking,
it tries to fire but just not cylinders firing to start

 

You shouldn't be getting 19V for a few seconds before it climbs to 48. That said, if it hold 48V during the actual cranking, then it is possible that you have something else going on as well.

Do you know what your ICP and IPR duty cycle numbers are during cranking?

Hey Ed thanks for the response..

I do not know how to check the ICP, IPR..
can you direct me to somewhere to troubleshoot them ??
Oh.. I sent my FICM to Circuit board medics for diagnostics today..

 

did the test and, key on engine off 47 to 48 volts. cycling 25 to 48 volts. engine turning over 35 to 48 volts. 06 turbo power stroke, 93,000 miles, high volume air intake and exhaust and bully dog. for a week or so had very rough starts and missed like crazy for 5 blocks, then it was warmed up and ran good. last day or two starts are so bad i'm waiting for it not to start, and missing so bad i have to let it warm up 3,4,5 minutes ant then it is warmed up and runs good. codes came up, fuel injector module performance, and fuel injector module test incomplete. the problem is after it warms up it runs good as far as i can tell. so far i have not heard if a ficm problem goes away after warm up or it does not go away after warm up and it costs a lot to buy a ficm (or rebuilt one) and not have the problem fixed. looking for help, thanks.

 

Your symptoms are stereotypical of a failed FICM. Your voltage readings are going to dip down further at colder temperatures (startup) as the amperage draw through the module is dramatically higher at that point than when the engine is warm. For now, the voltage climbs back up when the engine warms up since the amperage load drops. This will eventually not be the case and your module simply won't allow the truck to start.

Ship it on over to us at FICMrepair.com and we can hook you up! There's an intake form on the site under the 'Sending Your Unit in for Repair' tab with all of the options detailed. If down time is a challenge for you, we can also do a core exchange for you where we would in nearly all cases be able to ship a ready-to-go (plug and play) module out same day. In fact, you could elect to use this opportunity to get a tremendous update to the factory software on the module by electing one of the PHP tunes that we can apply in-shop! Just give us a call at 515-897-4459 if you want to set that up!

Sorry you are having trouble, but we'll get you going again!

FICM problems solved ..Thanks to Circut Board Medics Honest,friendly and fast service ..
19-48 volts cycling ,48v key on and cranking.
my truck started with the first crank ..
Guy's at Circut Board Medic "THANKS"

PS. my hair is comming back rapidly..

 

Hello everyone, I am new to the site and i am haveing problems with my 2005 f450 was driving down the road and all of a sudden the truck just stopped running and now will just crank over but wont start... i have since had the ficm replaced and removed ipr valve cleaned it and replace screen and orings and still no resolve.. any ideas of what the problem could be?

 

This sounds a while lot like a snap to connect fitting on the high pressure oil pump. What's your injection control pressure during cranking? If not 500psi or more, you've found the issue.
