2005 NO Start...silly 6 liter...lol

[Fatzack55]

I have checked the fourm and found several helpful threads since I am yet to get a clear answer on what is goin on here i figured I would join and post.
so you 6.0 junkies can get me back on the right path... lol

2005 6.0 250 XLT....160k, replaced ficm 15k ago with 58v...still testing good, good batteries, fresh oil from ford, new fuel filters, p2285 code

Ok heres the skinny..... few weeks back truck was parked over night.. come outside next morning wont start....so I drove my backup truck to work.... come back home at 6 and the truck fires right up.... but it has a CEL so run up and pull off code p2285... I clear the code and truck goes back to perfoming as usual until a couple days ago.... no start again....I had done a little reading from the first code and realized it prob had something to do with the ICP... SO i unplugged the ICP... still no start so i plug it back in...Still no start... after waiting and hour to call a tow truck.... I get pissed and decide that I am gonna start the truck... So I unplug the ICP again and it fires right up... take it back up to oriellys and pull the same code p2285.... This all sounds like a BIASED ICP.....

Couple side notes.... Sometimes when I turned the key on the injectors would not cycle.... sometimes they would.... dunno what might cause that...

I dont build oil pressure on the cluster until I have cranked on it for 10+ Seconds.... is this normal?....

someone point me in the right direction....DO i need to be testing the HP or LP oil systems.... or start with the ICP since that is the code I have...is there a way to test the ICP before I start throwning parts at this thing....

Thanks,
Zack

It def sounds HPOS related, the gauge should not take that long to respond. You need a shop with IDS to properly narrow down the search or you can pressure the system up and see if you hear anything but the proper diagnostic will save you time and money.

Where are you located?

Springfield MO


The HPOS can be checked with the bowl test... or is that LPOS?

[Dave At BD Power]

That LP....

Contact BD's sales department, they can see if there is a qualified shop near you from their dealer list that can test and take the guess work out. I believe there is Ferguson's Diesel in Springfield?

You really need to get someone to scan the truck while your cranking it to see what the oil pressure is while cranking. Most likely its a bad STC fitting. A leaking STC fitting will cause a no start condition.

I tested the ICP with a DVOM I got above 1.20 DC everytime we cranked on it...I read if it is over .80 then I am ok... Which leads me to beileve the HPOS is ok.... correct? whats next?

An intermittent issue like this tends to be something electrical, I think your STC is fine. If it were bad, it would be bad, there's no going back ond forth on that.

It will be tough to diagnose without the proper scanning tools to see what the engine is doing. Was the ICP oil soaked?
