new to this web site and need help!

I have a 2006 f350 6.0.
It has a rebuilt ficm, dummy plugs

I had a edge evolution on it and took it of an sold it two days ago( sct is on its way). When I took it off and sold the chip, I went to start my truck and it started prefect then started to idle badly. Sounded like a bad lope tune. So i shut the truck off and tried restarting. I got the same result. So I pulled the truck forward and after about 1 min the truck ran fine after it got to temp.

So then I let the truck sit for 2 days not driving it and not plugged in.

I went to go start the truck and it would not start. Cranked and cranked and cranked. White smoke like crazy. So I plugged the truck in and went inside for 2 hours and came back out and tried to start it. Cranked right up but started the bad lope again then after it got to temp it ran fine

Engine light is on and it pulls
P0683. Glow plug control module to pcm communication ckt

P2284 injector control pressure sensor ckt range/ performance

P0000 info not available

P2288. Injector control pressure too high

P2623. Injector control pressure regulator open

These symptoms happend right after I unplugged my edge. So I'm guessing it has to do somthing with this. Please help me!

Should I get my truck flashed? Should I wait till my sct gets here?
should i buy a new pcm?

sorry to write a book but i need my truck fixed!__________________

 

Hi Mike, welcome to DB.

I know you're new here and you're probably overwhelmed and stressed about getting the truck fixed, and we can help you, but why do you think getting it flashed would help? Why would you buy a new PCM? Are you just shooting from the hip here or do you have a reason why you think these things should be done???

I'll tell you exactly what I tell all of the new guys here. Throwing parts at it wont fix it. I mean, it might, but you don't really know what fixed it then do you? This is the main reason IMO why the 6.0 gets such a bad rep. Someone just keeps throwing parts at it over and over and never fixes it, but spends a TON of money in the process, then blames it on the truck.

With that said... diagnose, verify, repair. Three simple steps. We can help you with your problems.




Sounds like you have a couple issues. What's the temperature where you're at? A sluggish start and then running fine when it's warm could be a glow plug issue. Do you have a multimeter that you can test the glow plugs and the GPCM with? The GPCM is located on the passenger side valve cover. Disconnect the 4 pin connector at the valve cover. Measure each glow plug resistance to battery ground, the glow plugs should fall between .1 and 2 ohms. Then measure the engine harness resistance to the GPCM, those should fall between 0 and 1 ohms.

I don't believe this to be the main reason of your no start though. It sounds like your IPR valve is stuck open. This valve is located behind the turbo on the drivers side on the back of the engine down in the abyss. I would pull that first. To me it sounds like it's stuck and not letting the truck do what it needs to do to build high pressure oil to get it to fire. The truck needs 525psi of high pressure oil to get started, otherwise the PCM wont even turn on. If the IPR (injection pressure regulator) basically controls the amount of oil allowed to flow through the high pressure oil system. If it's hindering anything your injectors aren't going to fire, or they will not fire properly. Pull it out and inspect it, see if there is a lot of crud on the screen.

Another thing you can try much more easy, unplug the ICP sensor (injection control pressure sensor). It's in the passenger side valve cover right near the GPCM on your 06. Just unplug it and try starting the truck, see if it changes anything.

How old are you batteries?

I doubt the Edge was the contributing factor here, more than likely just a coincidence, but thanks for noting it, I will keep it in mind as we get through this.

 

thanks for helping and the quick reply

Batteries are good ( just tested them)

I did unplug the icp sensor on the truck and started it. same result runs terribly for a minute or two then starts to idle fine

im going to test the gpcm tonight after work but like you said i dont think that is my main problem here

when took the edge off i sold it right then. after the guy left i went to start my truck 5 mins later and thats when therse systoms started. i really do think it has to do somthing with the edge.
The edge plugged up to the map sensor and the pcm(middle connector). This is why i have been leaning towards a problem with the pcm.

My other question is: can pull the ipr valve out and just clean it and put it back in or should i buy a new one?

Just adding this in there: The truck will only start if it is plugged in

once again thanks for your help!

 

Maybe this is more towards a glow plug issue.

How does it start when it's plugged in? Still idle rough? If it starts a lot smoother when it's plugged in, maybe the GPCM is your issue.

Ok, which Edge unit did you have? One of the fancy juice platinum with attitudes or something that plugged into everything on the truck?

As for the IPR, you can try, I've read when you pull them out you shouldn't even touch the part that goes into the HPOP! Just be very delicate with it, wash your hands before touching anything on it and keep the area around it super clean before you even pull it. There is a "rebuild" for it, it's just new o-rings and a new screen. I would pull it and see if there is any debris on it. It's possible it's bad, but I'd like to try and isolate it as the root cause before telling you to just buy one.

 

When the truck is plugged in it starts but does the terrible idle
After the truck warms up and let's say I drive it to the station, it will start again but still has terrible idle

The truck will not start if its not plugged cold

I had the edge evolution witch plugged in at map sensor and pcm( middle connector) that's it

I will try the ipr valve when I get time

 

Ok good info.

Sounds like a combo then, the glow plug issue is making it hard to start cold, that's a relatively easy fix, but it also sounds like the IPR is hanging open or has debris in it. I'd pull it and inspect it (need a special socket for it). If it's got debris or the screen is damaged it may be worth replacing. I'd normally recommend just starting with new o-rings and a new screen, but being it's such a PITA to get at, just throwing a new one in might be the less frustrating option... Pull it and check it out and lets assess it from there. In the mean time you can test your GPCM with the multi-meter as well.

Let us know what you find.

 

I have the same problem with my 03 6.0 F 350. I was told it I needed to replace the ficm. Mine runs VERY rough until it is warmed up and then will be fine until it sits for a long time and the engine gets cold again. I have also noted that my fuel mileage sucks even more since it started running rough when started up. Does anybody know if these 2 issues are related?
I am a newbie here and unfortunately love trucks, but don't work on them myself.

thanks

 

Get your batteries load tested first, then test your FICM. The test procedure is at the top of the 6.0 page.

 

I would try a kam reset. the kam(Keep Alive Memory) stores all your map/turbo, transmission strategy since you did have a tuner connected from your map to your pcm that might be on of your culprits.If you have auto enginuity its real simple to do,or i think some scan tools have it as well. If you dont have a scan tool i believe you disconnect both batteries for i believe 15 minutes. I will see if i can find the "offical" way of resetting from the batteries. Also you have to drive the truck for atleast 20 miles for a relearn to occur and temps need to be normal.

 

I'm new I have a 06 f250 6.0 80000 miles I just paid ford to do head gaskets studs and egr delete and since I picked it up in the morning it runs horrible like it is loping for bout 30 sec I have a sct livewire ts and a 4 inch exhaust and everything on the outlook monitor looks normal also occasionally i get a burnt oil smell in the cab
