I am working on a 2006 F250, 115k miles. I have replaced injectors, glow plugs, glow plug module, filters. Still will not start. FICM has 48v koeo, and during cranking. Can the FICM be bad, even though the voltage is correct? A snapon scanner shows injector 1 circuit low. No other codes. Diagnosis on scanner lists FICM as possible issue. Anybody got any ideas. This thing is killing me.

I have 860 psi cranking. Would 1 injector keep it from firing?

I just got done replacing all 8 injectors on mine. Afterwards still wouldnt start. FICM also stated good voltage before changing injectors. Threw similar code only on cylinder 8. Check for bad wire on the Injector harness at the #1 injector plug. Now another thing that happened to me is after all was said and done the 8 new injectors strained the FICM to the point where I had to replace it as well. Good luck with it.
