Fuel leaves the filter on two lines to passages inside the heads. There are no "fuel rails" on this engine. Give it a read I have it pinned to the scanner cart. We do more trucks then buses and i would have to say 9 out of t10 time sits a icp pressure issue. Both syncs need to rad yes or there is a cam, crank issue. I use either the factory scanner or snapon solus but you almost need a good up to date scanner that will give you good live data. Hello here is the cheat sheet I use for the 6.0 fords. I thought it was over 10,000 psi to fire the injectors (more like 18,000) I could be thinking a different engine though. I have seen more than my fair share of bad crank sensors in the IH engines (which this is.)īeyond that: What is cranking Oil pressure? Fuel pressure? I don't remember off the top of my head, but 450 PSI for high pressure oil seems low. Personally, I'd start with the codes I have and go from there. Injector pressure regulator is also a very common issue on the 6.0 to fail i would really start with looking at the high pressure oil system! The person driving said it just stopped like someone turned the key off. When I turn the switch on I get all kinds of noises. when you turn key on do you hear anything or is it silent should hear injectors and glow plugs cycle? ficm needs to be no less than 45 volts as well. i would assume more to do with stc fitting on high pressure oil pump they are known to explode it needs 450 psi of high pressure oil on these to fire injectors. Yes eddo it is tested cam and crank both and they will throw there own code in the ford platform. Not sure if it is tested on a KOEO test, but I think it should be. Does the test not check cam and crank sensors ?Ĭrank sensor will absolutely cause a no start. When I run the KOEO test it says all is fine. ThanksĪlso, Ford has a fuel cut off switch up behind the passenger side rocker panel- at least my 06 E350 did. I think the filters were so bad maybe it destroyed the fuel presssure regulater ? Just a thought. I have another thought and that is the fuel pressure regulater.
ThanksĬheck the IDM relay, not sure where it's located since its a E450 but that's where I would start looking. Any ideas where to start or test ? I have oil and the gauge shows pressure during cranking. Later this afternoon I tried again and I could get some smoke and maybe a hiccup. I have fuel pressure I was able to bleed the filters. Cleaned things up and installed new filters. Anyway I ran the KOEO test and it said everything is fine.
No smoke and my scan tool said cam sensor was bad. I went to look at it and tried to start it.
