head or injector??? NEED HELP
first is exhaust in fuel. not a hard test, takes 10 min you should really do it.
second a ficm issue, yes, yes you have 48v, so what there is more to a ficm then voltage output.
you have spent alot of time and money tring to fix this so far. Maybe a little more diag will go along way.
fyi Im leaning to exhaust gas issues, but have see same from ficm's
I left the valve cover off and cranked the truck over and oil seems to be coming out of all three old injectors. I think the o-ring that the oil rail slides into is maybe gotten hard or just worn out. I notice these o-rings dont come in the injector oring kits.
What should I do the truck has 185,000 on it.
Try this... AP0002

I had one that the injector did not get tightened down from the factory enough, and the copper combustion gasket burned out and then eventually burned out the fuel o-ring on the injector causing fuel to dump into the cylinder and combustion gas to aerate the fuel and causing it to start, then die and not restart for a short time.
I would check your #8 injector installation first, then the rest of them, considering you have combustion gas leakage on the driver's side. Sometimes the copper falls off and you miss it when installing the injector. I had that happen once, but caught myself when I saw a new copper sitting around. Good thing I hadn't put it all back together yet.
There is still a bunch of smoke coming out of the exhaust. fills the shop up quick.
Buzz test no codes present
koeo had a ckp code so i replaced that
now the only codes im getting is a P2284,P0281,P0263
According to the scanner the P2284 is a icp circuit range/perf. does that have anything to do with the ipr valve?
ipr% running is jumpy around 28-30 but I think it went to 38% when I reved it up.
Thanks
would that p02284 code be the icp sensor bad? I tryed to unhook it then it just dies.
I would have to know icpv and icp# both koeo and koer to make a suggestion.

The ficm off the wrecked truck wouldn't have to be programmed would it. It was a 04 too.
Cheezit im going to get the info you was needing tonite. I have a new ipr laying here but was wanting to find out if a bad one would make it act the way it is or not. The truck is at our other shop about 15 miles away and have no internet service there.
Also just curious shouldn't the truck still run with the icp unhooked bad or not?
Thanks for everyones help much appreciated!!!
koeo: icp (v) 0.25
icp psi 0
ipr 15%
koer: icp (v) 1.54 jumps up to 2.54 seconds before it dies
icp psi: 995 psi
ipr 32%
I notice as it was cranking over and it wasn't starting the icp (v) jumped from 1.40 to 2.57
I did the fuel test again and guess what I have bubbles coming up thru the stem in the center again? I know I installed the injectors carefully and torqued to specs. why do I still have bubbles when all eight injectors are new?
The koer test showed 1,5,7 injectors contibution fault.
I did a koeo test and a buzz test before I done anything and both said no codes present?
I would see about those bubbles. If you unhook the two fuel lines that go to the heads at the bottom of the filter housing, one at a time, you can check to see which head is causing bubbles in the fuel system. Install a gauge with a hose on the line going to the head and crank/start (whatever it happens to be) and see if the pressure increases. If so, the head that the fuel line goes to is leaking combustion gas into the fuel system.
You lubed the o-rings with oil before installation to keep from damage during install?
All the copper gaskets are present and did not fall off? Usually a missing copper will allow the engine to run for quite a while before combustion gas burns the o-ring out, so I don't think that really is the case considering all injectors are new, which come with all new o-rings installed.
You can pull the injectors out and re-install them with reusing the o-rings when the o-rings are new, as long as you are careful. They aren't as susceptible as the old 7.3 injector o-rings that you never reuse. So if you are worried about pulling them back out to inspect, I wouldn't hesitate to reinstall the injectors with the o-rings because the engine has not run long enough or got hot enough to weaken them in any way.
Are you replacing injectors to cure this problem? Was this the main reason for replacing the injectors?
I don't know what else could cause air pressure back through the fuel system...Dead head fuel system (no return after injectors), injector cups can't leak combustion if cracked without getting fuel and/or combustion gas into the cooling system. A cracked head MAYBE, but I would think you would have cooling system problems first before this type of problem.
I lubed all the orings before installing them. I notice also the return was bubbling all the time. Is that normal?
I installed the injectors due to 5 had a high circuit or low cirrcuit code and with 185,000 on the truck I always heard when they start to go the others are not far behind.
at least the truck when it does start it revs right right up fine not like before just to 2,000 rpms before it dies. Still smoking really bad it will run you out of the shop if you leave the doors closed.
Nobody has a pic of the black stem inside the fuel filter housing I think there is something broke on this one. Dont know if that would cause bubbles or not.
Thanks
