So my truck has been doing pretty good, but I got a CEL the other day and was just curious as to what it was, I get a p0261, 264, 267, 270, 273, 276, 279, 282. Which is all 8 injectors low circuit, then I get one that says ficm control mod perf which is p0611, she seems to be running fine, just a little sluggish when cold which I thought is a trait of these, just wondering what else y'all had

 

Sounds like a failed FICM. What voltages do you have on Power and Logic?

 

Oh, and I just put 2 new batteries in it this winter, so I doubt it's that

 

Power is 47.5 as soon as you turn the key on but it'll drop to about 44 after a second or two, I'm not sure about when cranking because I borrowed the scan gauge from my buddy. I did that like 2 days ago and I figured it would be okay. I was just wanting someone's opinion besides my own

 

Anything under 45v warrants repair. If you can get your hands on that SG2 again, try getting some more readings when cranking, and while driving.

Your bad batteries could have caused the FICM problems.

FICMrepair.com can give you the hookup on your fix.

 

I'll look into that, or may swap him ficms for a couple days and see if it changes anything thanks for your help

 

9 codes that say "Please send me to Ed@Ficmrepair.com for some love".

 

Now, THAT'S funny.

Seriously, though, your FICM needs to be serviced as these guys are indicating. It may well be that your batteries failing over the winter killed it.

Ship it on across and we'll take care of you!
