Help Needed 6.0 sudden no start.

EGR Valve

No it would not, that component is for emissions only. you should air test the ICP system to check for leaks that way, there is a allen plug in the top of the HPOP and all you need to do is put shop air to it, pull the oil fill and plug in the other valve cover to listen for leaks. And your early model 365 is known for branch tubes and SCT fittings so if your issue is high pressure oil I wish you luck, how about fuel? You said white smoke which indicates low cylinder temps. Check the fuel filter bowl for pressure but keep in mind that you need ICP to operate a HEUI injector.

I cracked the fuel bowl and turned it over, it puts out fuel. I would have to get it towed to do the air test. What I dont understand is how this happened overnight.

Overnight

These thing can happen at anytime and anywhere under any condition, if they are going to break trust me they will, The no codes issue would concern me though, your ECM/IDM should have logged something.

 

[The Extractor]

I think I screwed up there because I disconnected and cleaned the battery terminals.... my buddy with the scan tool had the flash screen or whatever it is called. Ill try to get a copy of it...

Battery

That might have done it depending on how long they were disconnected for. Usually KAM or keep alive memory will store active codes with the power cut off from it, Does your friend have the ability to view signals ie. oil pressure, coolant temp, ICP pressure, engine speed? If so that might give you an insite on what's happening with your truck.

 

[The Extractor]

yes and they all were doing something but the throttle position wouldnt do anything no matter what we tried.

No start

Do you have idle validation? That might be why it will not run, what kind of numbers were the ICP and oil pressures at, you need roughly 500-600PSI of ICP to start that engine, and if no low oil pressure or lube pressure it will not start.

 

[The Extractor]

he doesnt know really all the ins and outs of the software and neither do I. I dont know what idle validation is... I dont think it had an option to check the icp pressure... Im going to try to get it towed to work tomorrow and another guy has a different scan tool that I hope I can check all that stuff.

If only the icp is bad and I unplug it theoretically it should start ?

 

[DaveBen]

No the EGR would not cause a no start. Im guessing FICM (fuel injection Control Module) or the Glow Plug Controller. Try plugging the block heater in and see if it starts.

Icp

No the system does not work like that, if you jumped a good 12 volts to the IPR and it started you would probably be looking at a faulty regulator or bad wiring, the air test is the best way to check you high pressure oil system for issues.
