Did my head gaskets no start. Bought a innova scanner and it came up with a p2285 icp circuit open I changed the IPR still no start. Checked the voltage on the ficm and got 48v on all 3 tests. Unplugged ICP and still no start. took fuel cap off and turned key on and fuel pours out. before I pulled the plug on the icp I read the codes again and I am still getting p2285 low circuit. It doesent even try to start. The icp is about 2 years old. Any ideas would really help me out I am without a vehicle and am relying on rides. Thanks in advance guys I appreciate all input. 03 f250 6.0 4x4 oil cooler, arp head studs OEM gaskets, New oil cooler, egr delete sinister, 4" down pipe, 150,000 miles, When I did the head gaskets the instructions said to turn the balancer so the mark was at 6:00 and I did that I dont know how the truck timing works but wasent sure if this had something to do with it. Everything went back in the same exact spot it was removed from. as far as moving componets that were dissasembled in the gasket swap. Heads were checked valves lapped. I am lost .

Current codes
p0046 Turbo charger boost control solenoid circuit range performance
p0405 egr sensor a circuit low
p2285 injector control pressure sensor circuit low

 

your no start is a result of the P2285

and the egr code P0405 is from the egr deleate

Motocraft oil filter????????

Time to start checking the Oil system start on the LPO side there is a oil filter drainback hold it down with a screwdriver and have someone crank it over this is to verify oil flow to the filter

here is a pic of the oil filter houseing and the drainback you need to hold down

 

If it did crank with ICP disconnected you would have know there was High Pressure Oil that the ICP wasn't reading. Now you know it doesn't have proper HPO. Stand pipe/dummy plugs, STC fitting, HPOP, I think IPR maybe. Pull and check screen is still there and no trash. Can't remember what the IPR duty cycle should be when cranking but IIRC 0% is full open ( no pressure) and should be something like 20-30% hot idle. So should be something in between.

Blade posted while I was typing. He's right check that stuff first. ^^^^^^

 

Ok so I have a new ipr hope it dident come messed up. It did clear one code I was getting pertaining to the hpo. Everytime I plug my scanner in I get different codes Now its reading p0098 air intake temperature sensor 2 circuit high input. Could this be because I have a charger on the batteries? now that we know it wont start with the icp disconnected. I guess I need to figure out how to check to see if I have aleak or something. I dont have dummy plugs I dont think. I have new stand pipes. I am a little lost on my next step. Do I take the valve covers off and inspect the stand pipes? I am getting oil in the filter housing and reading lpo on my dash. I replaced the oil filter again new oil. What would make the HPOP go out after a head gasket swap. I dident take it off or anything. I have an Idea that just popped in my head. Does the turbo run off High pressure oil? if so could a blocked turbo be stopping the high pressure oil at all? I am only thinking this because my old turbo was broken in half and I had to get a different one. I bought a used one and took it apart and cleaned it out but it was pretty dirty. Any ideas on this?

 

an 03 HPO setup is alittle diff no dummey plugs or STC fitting

The best way to see if you have a HPO leak is to use a gauge and monitor ICP and IPR%

Motocraft oil filter ??????????

the filter is important because the length of it needs to hold that oil filter drainback down
somee AM filters are not long enough some even used a diffrent cap to make up for the diff
AM filter companies have shure made a MESS of things

the turbo does not run on HPO a turbo issue would not stop the truck from making HPO the turbo does drain to the HPOP but it also has its own feed for HPO there is a HPO reservoir under the oil filter assembly that is the main feed thus a bad oil filter letting the housing drain would cause issues with the HPO system

Since you replaced the HPO standpipes I would think those were good maybe a oring in the top of an injector gotknicked or something hard to say best bet would be to monitor ICP and IPR% for HPO issues

so now you only have 1 code for IAT2

 

is there a different part number for the stc in the 03 all I can find is 04 and up.
after all the other stuff I did this seems like the most likely cause. New stand pipes new ipr new oil cooler and oil cooler screen. New filter and oil. From what I have read with 150,000 miles it should probibaly be changed anyway. Just curious about the part number in the 03 im looking at 4C3Z-9B246-F but says 04-07

 

there is no stc fitting on an 03

03s dont have the high failure rate of the HPO system

 

lol wow so I guess Its taking the valve covers off and checking the stand pipes. Where else could the hpo leak be any ideas?

 

Seen one leaking the other day at the injector TOPwhere the HPO rail goes into the injector TOP

another option would be an air test but its a PIA on an 03 but may help pinpoint the issue

 

dident mean to ignore this post for some reason I dident see it when I checked the thread. Good info Thanks.

 

Is there any chance that you left a ground off anywhere? Its weird that its keeps generating random codes to me. i am not nearly experienced as most of these guys but just
felt it was worth mentioning.

 

Dukie is the little ground wire from the FICM to the valve cover on .

 

Sounds like it might be a vreference short. Can you check the Vref voltage?

 

I just got these I have my drivers side valve cover off and no leaks here its all dry other than the oil I lubed the head up with. The ground on the valve cover was connected. There is one monster ground wire I have hooked up to the block but I'm not sure now that its supposed to go there. Its the steel braided ground comming off the firewall above and slightly to the left of the AC box.

 

I was wrong about FICM ground it goes on the intake manifold on the farthest one back drivers side.
