PO148

[Twan]

What would cause a PO148 fuel deliver code?

My fuel pressure is still at 68 psi, truck runs great, I've tried to clear the code but it comes right back.

This is on my 06 6.0

Found this for that code:
AT5 DIAGNOSTIC TROUBLE CODE (DTC) P0148
Possible causes:
Fuel quality
Crankshaft position (CKP) or camshaft position (CMP) signal noise
Retrieve and record all engine and transmission DTCs.

Also in the 6.0 Manual: P0148- Fueling Error - Engine RPM has exceeded requested RPM. - Alernative fuel source, interferance on CKP & CMP, faulty PCM.

Try putting a scanner on it and see if there's any other stored codes in the system. Also check FICM. May set the truck back to stock and see what codes come up then.
