FICM failure ????

ok so heres whats goin on i have an 06 with 48k on the clock an i think my ficm is failing, when i go to start my truck i have about 44.5v on average sometimes 48 the other morning it was 42 thats the only time it was ever below 44v tho (an it coulda been because i was using my truck as a stereo for a camping trip with out starting it for 3 days) but once my truck is running for a min or two it goes back up to 47-48.5v an stays there any input would be helpful thank! oh an i have two brand new interstate batteries so i know its not my batteries

I would say it's your FICM that needs to be replaced. I advise you get it corrected soon, and not allow the condition to compound itself and give you a couple of failed injectors to boot.

If your looking to save at all, I just had my FICM tested and was only putting out 38v while it was running... Sent it to a guy I found on eBay in minnisoda to rebuild it for $120, that included shipping both ways..came back the same week good as new. Tho now since it was putting out only 38v, I'm now replacing my number 5 injector, so don't procrastinate.

I just got mine back from FICMrepair.com. Very quick turn around and can have them tune it for a little more $$. I had the atlas 40 tune put in mine and what a difference.
