2002 no power 1900rpm thru redline
So my 02 has been acting strange. As stated it has now power. Idles fine dri ves fine if your light on the throttle taking it no higher than 2k rpm. I changed the oil and filter, the fuel filter iat the front of the engine. When you floor it and it downshifts the tach will drive up but slowly. It used to run hard up to the red and have ample power to do so.
I changed the icp for a new one thinking that was it but no change. I had removed my 5.6k resistor because it idles lopey with it and the new icp, idled fine before. So it wasn't the icp. Before I changed the icp I noticed when wot it smokes a light brown, not black like it used to when I bought it. I was told there's a spring and check ball where the return line goes back into the pump on the rail and if the springs broken it'll cause low fuel psi. I always buy fuel from the same station and have gone through 3 tanks since it started.
So what should I check? I looked at the boots connecting the turbo piping and they're connected and don't seem to leak. I can hear the turbo spooling so I know its not a boost issue. Judging from the brown not black smoke id guess its not getting fuel. There is no check engine light on.
I really need to getg this thing fixed, I use my truck as my daily and as my tow truck for my repo job.
The truck is an 02 4door 2wd auto 7.3diesel, k&n filter, straight pipe muffler. It had a 5.6k resistor but I removed it due to odd idle with new icp.
