6.0L won't start

[osimmons1]

i just bought a 2004 F-250 Super Duty with a 6.0L was driving home when i lost all throttle while truck was in gear. when i put it in park or neutral the engine would rev up. went back to get the truck and it wouldn't start. got it home pulled codes and they said injector curcuit high on cly 2,3,5. checked voltage at ficm it was at 48V. any ideas what my problem is.

thanks for all your help.

is there any chip on this?
whats the oil level?
might wanna check into the blue spring update.
make sure u only use OEM fuel and oil filters.very importan!!

usually a no start is caused by a hp oil leak. if its '04, could be icp(injection control pressure sensor) or hpop. or ipr valve.

And, you need to check the FICM voltage at three different times.
Once, key-on, engine off and cold
second, cranking the engine over, engine cold
third, just after engine starts above.
One check won't give you a good grasp on what your FICM is really doing.
You should also check the batteries. Have them load tested at an auto parts store (its free). Replace the batteries as a set if either one of them tests as marginal or fails. When you get the batteries home, place them on a charger and get them up to a 100% charge (even if you bought new). THEN check your FICM voltages. Checking them this way will give you your best result.
If you can monitor your ICP, ICP desired and IPR% when cranking the engine over, those will tell you if you have a high pressure oil system issue.

Did two of the three test key on engine off and cranking engine won't start for the third the batteries are good. already changed out the icp sensor. how do i monitor it?

no chip oil level is good. what is the blue spring update?

I just went through a very similar situation. I had injector circuit high codes for cylinders 2 3 5 8. What do these have in common....all are controlled at the X2 (middle) connector plug on the FICM. I was reading all of the proper FICM voltages at cranking and start up. I traced all the injector pin locations back to the FICM. The "coil power off" signal pins for those injectors all share the same connection on the logic board inside the FICM. I swapped in a known good FICM for a quick check, all the codes cleared and the truck ran fine. This may just be the problem I was having, but I would check that first. All the codes showing up for cylinders on the same connection is more than a coincidence.

If the FICM swap doesn't work. The injector harness should be checked for a short.

Changing out the original fuel pressure spring with the updated version.

I have a 06 ford f350 turbo spools up no leaks getting 5psi cleaned map sensor hose and nipple cleaned bp sensor need help

[joe_r_dog]

probably sticking veins in the turbo. if so, it would need to be removed for that.

[Welder361]

Vanes already clean and added new unison ring got only 5psi no power
