OK, I just put in a new crank sensor an a different wiring harness, FICM balance rates are back to normal, no codes an the truck runs like shit, no power, cutting out, blah,blah. Compression is perfect, I even pulled the injectors an had them checked on a BenchMark, I checked the valve lash, WHAT NOW????????
I don't know what else it could be except the ECM,

Current Balance Rates

When you changed the harness and sensor you didn't switch the cam and crank sensor wires up did you?

 

[wdino73]

No,

short lead to the crank, long lead to the cam

Have you tried a full flash of your tuning again?

 

[S Phinney]

Checked all the grounds and made sure they are grounded good?

Have you tried a full flash of your tuning again?

I've done a full flash with a good tune I've used in the past, I also full flash to the original stock tune,

I've checked an cleaned all the grounds on the right side, I've not done the left side yet, I'll do that next.

Have u checked all the pins in the bail connectors on the big plugs to engine are not pushed and not contacting correctly? I had that happen one time where a pin got pushed in & ran funky til I got the pin pulled back out so it contacted in the plugs correctly.

Sorry, I'm just grasping for straws. There's not a lot of things that just stop working all of a sudden like you described previously when this started. & you've checked dang near everything else.


Later bud

your gonna have to start checking all the sensors and making sure they are reading what they are supposed to and checking all the stuff with the scan tool.

and grounds grounds and more grounds gotta be clean

Ok, thanks anything else, Here's alittle update I did find a boost leak in the y-bridge installed new gaskets in bridge, Drive it up the road noticed the egt are way low like 490ish, a few miles up the road they jumped to 800 ish, an the truck was running fine, but it was short lived, back to the loss of power an low egt's. It must be an electrical problem, something to do with the fueling I just got to find it now, Atleast there's hope,

i have asked you again but reminded me... who is doing your tuning?

 

[wdino73]

Trent an I, but it does it with the stock tune, a tune I use to run before all the mods. with ppe, It doesn't matter what tune, It's like one of the banks aren't fueling, driving me nuts. an of course no codes.
