2006 F250 6.0L died on highway and no restart.

Help!!!! My 06 F250 has been having some issues, I have the egr deleted, upgraded oil cooler, new IPR valve, upgraded STC and new HPOP. Still no start. I'm lost. I just ordered dummy plugs and stand pipe. Am I heading in the right direction?

also the FICM check out good with 48 volts with key on and turning engine over.

You need a monitor like a scangauge or a scanner so you can see what is actually going on in you engine. Voltages, Oil pressures, temps etc. This info is needed to properly diagnose a modern computer controled engine. Without it we are all just guessing, edjucated guesses but guess none the less.

Yes I deff. need one. Owning one of these trucks and being strapped on cash dont mix. im just hopping i can get some tips that maybe i havent thought about yet.

Ok I will have a scan tool this evening. what are some things i should look at on a live data stream.

you need to program in the xguages. video is on you tube.
ficm main power (FMP)
ficm logic power (FLP)
ipr % (IPR) icp voltage (ICV)
icp pressure (ICP)
there are many more but thats a start

[clarkja]

Ok i connected scanner and turning the engine over the ICP was showing 365 psi with ipr at 85%. i sprayed a lil starter fluid to start the engine and at idle the ICP showed 913 psi. i let the truck warm up and then killed engine and tried to restart the motor and the ICP showed 175psi and the ipr at 85%. the ficm showed 48 volts with key on and 48 volts while canking.
seems that i have a leak.. does any of this highlight a problem?

[Kyle K]

DO NOT use starting fluid!

[clarkja]

okay no starting fluid!!!!

[Kyle K]

You need at least 500 psi on icp to start. Have you tried unplugging the icp sensor and trying to start it? Its on the pass side valve cover for your engine. when you unplug it, default icp goes to 1500 psi or so.
