P1211 Code
Hey Gang- this is my first post. I just installed single shot Stage I injectors in my 2001 7.3 Powerstroke this weekend as well as rebuilt the turbo with the 1.0 exhaust housing and wicked wheel. I also had the chip reburnt with the new codes. The truck runs great- but I keep getting P1211 codes lighting up my Check Engine Light. I can clear the code and it will not come on again until I kill & restart the truck. The truck has never had any issues prior to these upgrades. Any help would be greatly appreciated.
Already had 4" exhaust, Stage II AFE Intake, and a DI Performance 6-Position chip.

A P1211 means your HPOP can't keep up with the demands of your tunes, which is weird because you said you just installed single shots.
Single shots take less oil to operate than the stock injectors, so the tunes shouldn't be calling for more oil than the HPOP can deliver.
Someone better versed in custom tunes will have to chime in.

Thanks
Gents- thanks for the welcome and all of the feedback so far. It sounds like I need to check the o-ring or popet valve- I assume on the ICP?
I forgot to mention that I have installed an externally regulated fuel system- would I need to adjust the fuel pressure and would that possibly be causing the code?

Shooner, If you can get or have access to a sacnner ( AE or A snapon ) you can see the high pressure oil pressure at all engine speeds even while cranking. That would by your best bet.

The ICP is a simple pressure sensor on the oil rail on the driver's side head near the front of the engine.
There is no adjustment on this; if it is good, it is good, if it is bad, replace it.
A P1284 code indicates a failure of the ICP sensor.

Update
Updated Information: the Check Engine Light comes on immediately when the key is turned- before cranking the motor. I have used a live scanner while driving and all readings are within operating range. There seems to be something triggering the code when the key is turned. Again- If I clear the code with a scanner- it does not come back on while driving and all scanned readings are good- so the ICP snesor is good. I hope this helps...

Hmmm, I'd contact your tuner and see if he has any ideas.
Because there's nothing mechanical going on at the time it occurs (engine not cranking, just ignition being turned on), I'm thinking maybe a glitch in the custom tune, if that's even possible.
