I'll cut to the chase. Truck will not start without ether period. I absolutely needed it for a job today there was no way around it. After a 20 min lunch break at Wendys I came back outside and cranked that pig flat to the floor for almost 30 sec and it just would not light. Almost 130,000 on everything I suppose the entire fuel delivery system is shot and air leaks hideously. Unfortunately since it was already heat soaked the ether lit far to advanced and it knocked horribly. About a half hour later on my way home it now has a loud upper end tick. It sounds like on the driver side of the engine and honestly sounds the loudest coming out of the air cleaner. So did I do this, or is this just a coincidence? I'm guessing these idi's have hydraulic lifters, could one of them have given up the ship?
I'm not a complete imbecile I truly hate using the funny juice but I am VERY busy and I DO NOT have the time to do injection pump, injectors, and return line replacements and all that other crap until winter. Unfortunately now I may have to find the time to swap in that first gen 6.9 with the turbo that I bought a few months ago anyway.
So now a tech question. Why is the almighty, powerful, thermodynamically efficient unrelenting juggernaut known as the Diesel engine such a finicky, temperamental cry baby ***** when it comes to air in the system? If these injection pumps have thousands of psi why doesn't the air come blasting out of the injector and the engine light a few seconds later? When you crack the injectors the fuel goes flying so why can't it purge itself? I'll be willing to venture a guess that the air compresses just like when there is air in a hydraulic brake system and that possibly makes it hard to purge through the injector orifices? Please someone educate me here. I have never had a injector apart, old school or HEUI's so I hope if I knew how they work (I know the heui's in my DT466E are a entirely different animal ) I could better understand why they can't self purge.
Thank you everyone. Heading to bed annoyed and disgusted. Tomorrow is a different day.
