2003 no start

[Johnswiftm]

I am helping a friend on his 2003 F350 with a no start condition. I plled the codes and got a P0611 and a P2552. I ran a check on the FICM and had 48.5 volts before cranking and 47.5 to 48 while cranking. The injector buzz test was good. He said it had a crank and cam sensor code on it and replaced both of those. I looked into the valley and didn't see a bunch of oil in there. The code P2552 FICMM code I think is the culprit but I don't know alot about the 6.0. Any help would be appreciated,

I am not familiar with P2552. But the FICM will give you problems starting and then die. Here is a site to check out your FICM and get it repaired if it needs it. ficmfixer.com

po611 is ficm performance code p2552 is a circuit code related to circuit in accelerator to ficm wiring. 1st you need to look at data and check if the '' ficm sync'' says yes when you are cranking the engine. also look at the connectors to the ficm are they properly seated and tight?, cam/crank sensor codes are almost ALWAYS set on a 6.0 no start even when the sensors and circuits to them are working properly. you need 48v +/- when the truck is running not just in crank. p2552 will cause po611. look at the accelerator pedal wires closely.

Finally found the problem it was the ICP Sensor was bad. Thanks for all the input!
