  1. Low FICM voltage only while running

    General 6.0L Discussion
    Howdy all! So I'm almost finished with my cab-off engine swap. Got the cab lowered Sunday after church, and most everything put back together today. Not sure where to start describing this issue, but here goes... The truck started after a good deal of cranking to prime the HPO system. It runs...
  2. 97 7.3 Voltage Swing

    94-98 7.3L Problem Forum
    Have had this problem for years, voltage swing from 14 - 14.7 v while running, engine runs smoothly, but you can see the swing corresponds to engine/belt movement. Alternator good, all new batteries and cables, rebuilt standard swamp's injectors about two years ago, new ford idler pully and...
  3. lights got dim and engine died on the road.

    6.0L Problems Forum
    So my dad was driving the 6.0 and he said as he was driving all the lights dimmed, the gauges all dropped, and then the engine died. When he went back out to tow it home it started right up and he was able to drive it home. I replaced the ficm's power board and the alternator about 2 months ago...
  4. FICM Voltage concern

    6.0 Motor problems
    I have a 03 F250 6.0 with 230,000 miles. I don't seem to currently have engine problems that I know of, but my Edge Insight monitor was reading wacky FICM voltages. Right after start, the voltage was dropping to 34.5 and eventually as the engine warmed the voltage was back up to 48V +/- .5V...
  5. Bad Voltage Gauge???

    99-03 7.3L Powerstroke Problems
    Hi all, I recently realized that my battery voltage gauge in the cluster is always pegged at 18v, no matter what the truck is doing. The the key is off, the needle drops down to about 11v and goes no further. It would seem to me that the gauge is faulty. I pulled up the volt gauge on my Bully...

  7. Aftermarket FICM?

    6.0L Performance Parts Discussion
    So I think my FICM is on the way out. I got codes p0611 and circuit low codes for injectors 1 and 7. The voltage is around 45v reading it through a scan tool. My question is what is the best bang for the buck FICM. If you have first hand experience throw your 2cents in.

    K so I read the write up on the 6.0 monitoring, and one of the things that i am curious about is the battery voltage @ start up!! The write up says to have at least 12.1v prior to starting but when i went to start my truck the voltage was only like 11.6-11.7v ! Is this bad to start it with this...
  11. ??Normal psi's, temps, volts??

    General 6.0L Discussion
    Not sure if anyone knows what the normal running temps are for eot, ect, trannie, ficm volts, etc. I have had my SCT livewire tuner for a few months now and would like to know what ALL of the norm operating values are. If anyone knows where to find a list of this info would be greatly...
  12. Voltage on Dash...

    99-03 7.3L Powerstroke Problems
    Bear with me as this will probably be a long post. Ultimately there are three questions… I have a 2001 Excursion (7.3) and it's generally running fine. As I was driving about the other day, the "battery idiot light" came on but the voltage meter that's "stock" in the Ford dashboard (along...
