I have a 2005 ford f250 powerstroke 6.0 I bought it drove it 2 hrs home and it died as I was turning in the driveway. So I tried to start it back up but it wouldn't I let it sit for about an hour then it started but now if I drive it after it warms up it runs rough and has no power then it dies It seems to run fine unless I get on it. I I have replaced the stc fitting, stand pipes, dummy plugs,updated turbo oil return, egr delete, and the ipr valve. I tested the ficm and its was getting 27v then would jump up to 48v so I took it apart and resoldered it now its getting 47 to 48 volts but I still have the same problems. Is it possable that The ficm is still bad? I tested The batteries and alternator they are all good. I would really appreciate the help.

 

There are a couple of other seals that it could be that can cause a hpoil leak, there are seals on top of each injector and also on the bottom of the oil rail itself on the nipples that feed the injectors. If you were to do a air test on it you could find the leak,basicall you hook an air compressor to the oil system by using a special fitting in the ICP sensor hole.

 

Ok thanks ill try it after work.
