6.0 wont start lots of codes

[460+]

Im working on a 2003 F350 2wd w/auto trans it has I think 140,000 on it. The truck cranks over but dosent even try to start, there is no smoke out the exhaust. I hooked up a fuel gauge it has 48-50psi and fuel is clean. I hooked up a scanner and it has several codes.
It has codes for cylinders #1,4,5,7 I cant remember the ones for #1,4,7 but # 5 is P0275 cyl 3 5 contribution /balance fault and #1,4,7 are the same.
P0046 turbo boost control solenoid circut range problem
P0231 fuel pump secondary circut low
P0232 fuel pump secondary circut high
And on e for the glow plug module but cant remember that one. The scanner reading on the icp was 250-289psi and said it should be 450 or higher but there isnt a code for it and also Im getting a signal for rpm so I dont think the crank sensor is bad. Any help or info would be greatful.
Thanks Rich

Could be the icp sensor. With all the injector codes i would also think FICM. You sure the codes werent; for 1,3,5,7? That would be one harness on the ficm and maybe it's wore through.

With no smoke, I wouldn't think it's the FICM...then again, I'm not a "tech". How are the fuel filters?

The codes were for 1,4,5,7 and I also thought of the icp. The fuel on top looks good I havent had a chance to look at the lower one yet. The shop I work at has me jumping around alot.

if the ficm is bad then the injectors don;t fire and you get no smoke. Although i am not a tech either. But i would first replace the icp sensor. Sux on that truck though. It's above the transmission on the back of the motor.

When my FICM finally went out 3 weeks ago, my truck would smoke every time it would turn over and the truck wouldn't start...I believe it still gets fuel in some cylinders when the FICM is bad but it does not fire, hence the black smoke.

That depends on if the FICM is completely gone or almost gone etc...
in my case, my FICM was gone so no smoke out of the truck

OK sounds right. The 2 trucks i seen witha bad ficm all injectors were throwing codes. So aybe none were firing.

Thanks for the replys. Is there any type of test to run on the FICM? We dont have any repair manuals on these yet, we are just starting to work on these.

I cleared all the codes out and reran to check for codes and nothing. I found out today the people that own the truck has been working on it themselves, so I dont know what they have changed or not.
