Skipping, no power and no CE light

2005 F350 6.0. Just did the EGR cooler and oil cooler, and installed a blue spring kit. Got it all back together and it's got no power, until about 2500 rpm, no black smoke, no CE light and it's skipping. Turbo is new, not rebuilt, as of about 2 weeks ago. The boost gauge indicates just a couple pounds of boost, until higher rpms under hard acceleration.

I'm baffled, as it ran great, before I started all this.

Also, the high idle mod is taking several seconds to kick in, not all the time, but that's not normal for this truck.

might wanna look down to see if intake gasket is broke, or that the egr cooler core-to-exhaust clamp is not loose. Also, if you did not disconnect all of the fuel injectors, theres a good chance that an injector connector may have been broken. I'd lean more towards broken injector connectors. 6.0's dont really throw check engine lights.

I did disconnect the injector connectors. New gaskets and they're good to go. The egr clamp is tight and no leaking.

Even though there isnt an CEL, there may be dtcs to help. Ive had those injector connectors "click" in, and somehow not make an electrical connection until I pushed and wiggled em a bit.
Ficm connectors fully clipped in, anf the ficm ground wire at the back of the driver side intake near turbo heat shield tight? If so id check fuel psi to avoid tearing the injectors up if pressure to low

Ok thanks. I'll run the connectors again tomorrow. I'll pick up a fuel pressure gauge too. Ground wire is tight and I didn't disconnect the FICM.

You know of anybody having problems with the blue spring kit? Mine had the cover and a black valve guide that I didn't need. The housing had the guide built in. Thinking about putting the old one back in and see what happens.

Tomorrow is another day...

Ran all the connectors, gave them all a good push and a wiggle. Checked all the FICM connectors, they're in tight. Checked the FICM ground, 0 ohms. Skip is still there.

I know this has to be something I did, because it ran smooth as silk before I tore into it. I hate when that happens.

i haven't heard issue with the blue spring and I would expect if fuel PSI was the prob you wouldn't see it clear up at 2500 rpm

the new turbo or atleast low boost seems to be the prob but i would expect smoke so IDK ?

you may want a more advanced code reader to scan the truck ?

Thumbs up

Fixed!

Like what has been said, it was a connector issue. The last one on the drivers' side.

Runs like a ten dollar Timex again.

Thanks for the help and suggestions!
