Exclamation Hard start, rough idle, then fine after up to temp!

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 now and I haven't got the codes read yet

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?
I've also heard tht it may be my batteries??

Bad batteries kill ficms, even rebuilt ficms. Load test your batteries.

Will do. Thanks
But it seems odd that it would happen the second I took off my edge.
Before I took the edge off I cranked up perfect!

Anybody else?!?!

It sounds like your spool valves are sticking. common problem when cold. injs may be on the way out. the sct tunner may help.

I pulled some codes now :

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

My guess now is icp sensor. Any suggestions!?

The icp sensor is not the problem. There is no oil at all in it. I also unpluged the icp sensor and starte the truck. Still ran like crap for the first few minutes.
The truck will only start if its plugged in.

I think my next step is to test My gcpm
Or could it be my pcm?

My problems happend 5 mins after I took my edge off. Witch the edge hooked up to the pcm ( middle connected) and map sensor.

Hmmm, yea the pcm may have been corrupted. Can you hear all the injectors buzz when you turn the key on?
