I installed a new ICP and now the truck wont start. The truck has a code says open ICP circuit.

Is there something Im missing....the connector is on..>Do you have to reset things?

reset computer 10,000 times now...!!!!!!!! Nothing..plugged in..unplugged.....left unplugged..nothing..

plugged back in reset...blah blah blah....

what's the secret...scrap yard time for truck... (and to think my friend spent 35K on one from a Ford Salesman...a 2005 with 17k ...hmmm bet he'll have problems

dead..no work

 

Is the connector covered with oil or was the icp leaking oil? If you answered yes to any one of questions replace the pig tail connector.

 

The connector is covered in oil....but it worked with the old one....so what gives.....

Ive wiggled and messed with it...

Where does that connector go to replace?

 

Cut the connector for ICP out....used continuity tester to ends....wires all have continuity to pins and not to each other....now i am an electrician and this to me would mean connector was fine...

So now what!!!!!!??????


ICP code says open...

why doesnt unplugging it work as it says in some posts here...wouldnt that let it have a default pressure so i could drive it to the junk yard!

 

I see that you are an electrician so you know what kilo volts are but the sensors sometimes work on millivolts and it does not take much to get a false reading. like brickie suggested you might try and replace the pig tail what have you got to loose. If ford finds oil in the connector they replace it automaticaly.

 

I can appreciate that.....milli stuff....

I just hate sinking more money into the truck. With the old sensor, the thruck would start...so wouldnt a new sensor allow at least the same?

maybe I got a bad sensor....but I wanted to be sure it wasnt anything else. I will get the pigtail..throw more money at this thing

The truck is for sale and i dont have the money to fix it..Ford wanted 500 for the ICp...so i figured Id do that at least myself. The truck ran bad after getting hot then would die..ICP type symptoms.

They also said i needed 2 injectors, one on each side naturally. But they were sticking when COLD..so it would start when cold...then run worse so i asked the guy at ford, he said do the ICP and see if doesnt make it driveable.

I am about ready to take it to ford, let them fix it, not be able to pay and see what happens...terrible? ya but Im desperate now... So thye probably put a lien on it and auction it...so it would cost 3000 for repairs, 2000 for fees for lien and auction..and Id get 8000 at auction..that is 3000 more than I have now!

Im just about ready to snap over this 6.0!!!!!!!!

Aside from the connector, since I bet that dont work!, what else would cause this?

No offrense to you guys, if it were everyone on here's truck they would have donwe the ICP and it would have worked. Im the ZOLOFT guy witht he rain cloud followin me...I need counseling or go back to vietnam and fire off a few thousand rounds!

 

The Injector Control pressure sensor needs to see about 500 psi of oil pressure before it will allow the engine to fire the injectors. So if the ICP does not do it then it could be the IPR which regulates the pressure or the HPOP or a leak in the oil lines coming from the HPOP. With out a scan tool to check these things it is very hard to tell what is the cause. I did read that when the ICP is disconnected that the default value given is 750 psi for the scan data. Also the IPR is in the same area as the ICP make sure the connection there is still good and has not been accidently disturbed. One other thing what is the code that you are getting. There maybe some of the guys that have seen it before and know what it is.

 

code 2623 icp open

Ford Diagnosis at an Ok dealer for giving the diagnosis...but expensive

ICP..no mention of connector but I bet they have it in price
2 bad inj...when cold sticking
No mention of oil leaks at HPOP etc

NEW ICP....wont start

???IPR infront of ICP..I notice the cap rotates where the connector goes in. When I was unplugging it, it would turn down whee I could get my hands in....like a old distributor cap you could rotate. it can turn 90 deg. It did it very easily when i changed ICP....is it designed to spin?

I aaumed so since i did not do anything to break. i mean I put pressure of a new born on it....but it does turn..do your's turn guys?

I may go by ford and "look" at the part see if it turns..maybe it broke?

Someone on here has to know if the connector will rotate..It moves from straight up to back horizontal to the road..facing back to the back of the truck...from facing up to hood.

I dont have another 6.0 2003....if I did I would see if it turns too.. It moves easy


Thanks everyone for info and patience..Im exhausted with the bad luck

 

P2623 is for the Injector pressure regulator not for the Injector pressure sensor. So you might want to focus your attention on the IPR. There is a test for the IPR you can measure between Pin 1 and Pin 2 to check the solenoid in it and you should see from 3 to 15 ohms. Oh and by the way pull the connector and see if it is made to rotate like you a mentioning. I do not have an 03 so I have no way to verify it. You can also pull the plug and measure pin 1 of the plug to ground with the key on engine off and you should see 10.5 volts. I hope this helps. If I come up with anymore info I will let you know.

 

The IPR is burried back with the IPC

How does it come out? I cant get to the pins to test.

Im guessing it shouldnt rotate.

So I am going to ford to look at one of theirs and see how it mounts and how to try to remove it bling back there and if it should rotate

 

oddjobs, with the host of problems that you have already had, maybe you should think about having the dealer buy the truck back as a lemon. get an oasis report, take it back to the dealer and have them buy the truck since it seems to me that you don't want it anyway. not sure if you can do it, but worth a try. good luck.

 

I looked at the new ICP at ford. It has some plate welded around the IPR that keeps it from spinning

A diesel guy at a good shop here told me the connector faces the wrong way sometimes once new ones are installed so he has to get a wrench on the end of one to turn the connector. So is it suppose to turn or is it broken?

If it is OK...what would make it open?

Another guy at the diesel shop says if they are ???? too long they will stay open. Not sure what or how he was saying...but would tapping on itlike a starter selinoid free it up?

Code 2623 INj control pressure regulator open

Not sure why the dealer would buy it back as a lemon? Do they do that? I got it from a toyota place in LA they knew as little about it as I apparently did (should have researched the 6.0) They are good people. Will Ford buy it back though as a dealer for Ford trucks that I didn't get it from?

 

Any ideas on a IPR showing OPEn 2623......cant seem to find why it is open?

Dont know how the IPR could go bad undriven after i just did ICP..>There is something I am missing

 

There is the possiblilty that the IPR was your problem all along and not the ICP. Ford did move the ICP over to the passenger valve cover because the heat was getting to them.

 

Mine is in back...so I dont know how ford knew it was an ICP...they did not mention the IPR

But It didnt give me the 2623 code until after I put in the ICP...and even if I disconnect the ICP and try to start it gives me the 2623 code

Using the OLD ICP gives me the 2623 code

What the heck got bumped?

Wire Harness to the computer thing over the valve cover (why would you put something like that over a valve cover by the way? My 4 year old could engineer it better!!!)
