injector control pressure too low

fault / trigger / comments
no start ICP is less than 725psi (it's a 360psi when cranking)

I am having issues coming up with the manual online.

Any helpful thoughts, or comments would be greatly appreciated.

Is the IPR around 85% while cranking?

most common thing I have run into on those trucks is the SCT bracket at the back of the HPOP will start to leak, there is an o-ring in there that gets worn out over time and creates a HPO leak, another possiblity is that one of the o-rings on one of the plugs in HPO rail could be worn out and also leaking. or an o-ring in the top of the injector could be torn, but the most common is the SCT bracket, ford sells an updated 1 piece bracket to correct that problem.

Thanks guys! Got it back on the road. I forwarded all the info from you guys to my buddie and he got it going. I was down and out and missed out on all the wrenching. Yeeeee! I don't even know what it was exactly. All I know is he told me to thank you guys for the help. So... Thanks very much to all. PSN rules!
