So I pulled my 2005 F350 King Ranch 6.0 in January, Cam was shot along with the lifters, total rebuild , .20 overy pistons, rods, reconditioned heads, stage 1 cam, hd lifters, new valve train components, pushrods. Reassembled very carefully, got it back in the truck Sunday, I have a No Start, engine seems like no compression, KOEO ;Ficm 48.5v, ICP .2v, IPR 14.7, .
KOECRANKING ; Ficm 48.0v, ICP 1.6v, IPR 81%-38%, something around 64%, rpm 186,Ficm sync 1.0, Cam vs Crank Sync 1.0, HPOP 1500+, fuel pulse width 1200+. This is driving me crazy, this is the first engine in over 35 years that has never started for me.....thanks anyone .... Dave

 

Is it building oil pressure?

 

Yep, builds over 1500 while cranking, but drops very fast when I stop, not sure how fast it's supposed to, I know it doesn't hold it indefinitely, it's not supposed to do that, I had a problem with a standpipe O ring, replaced it, not sure if that would be it, since it's building good HPOP.

 

Also today borrowed a ficm and tested the fuel pressure 75lbs, still no start, going to start drinking soon........

 

Glow plugs/GPR? I'm treating this simplistically as a cold start problem.

I think you must have some compression in the engine since your RPM when trying to start is 186. And from what I have learned, that should be enough. And it would likely be somewhat higher if you had no compression.

The other numbers look OK to me, but I will think on this and maybe contribute more.

 

New Glow Plugs ,Harness and GPR. Ford Diesel mechanic at local dealer stumped also, he let me borrow the ficm, guys at my Dealer are awesome, not out to bleed your wallet. Letting batteries charge will jump in again tomorrow afternoon, also thanks for responding. ...... Dave

 

 

All I have is Torque Pro, I'm not 100% sure but ,pretty sure I hear them when I turn the key on, along with the fuel pump , thanks. ..... Dave

 

I have a Mechanics stethoscope, wondering if I put it near an injector, when someone turns the key on would work? ??

 

 

Ok so I was able to download ForScan, performed an injector test, all is good on fact did all Pids, and everything came out good, a friend said he seen greyish, smoke from the exhaust and smells fuel, still no start...... Dave

 

Does it "try" to start (as in sputter but not catch)? I agree all numbers indicate a 6.0L that should start and run, by what you've posted thus far. If you loosen off the cold side CAC tube at the intake elbow, spray a bit of Brake Parts cleaner and try to fire it up and see what happens.

 

So I I've been trying everything ,even chaneed the Standpipes and dummy plugs again, found couple of nicks in the O rings, pressure doesn't drop as fast now, still No Start, haven't sprayed anything in the intake, don't really want to do that. Anybody come across this problem, ever ????? thanks Dave

 

Just wondering if all the cranking, maybe something could have changed the ECM ? If so how would I know and how to test it.
