Hi, need some help with this truck. When cold (80 degrees this morning) it cranks and cranks then starts and runs rough with black smoke. In a minute that clears up and it runs fine. If I shut it off, it starts right back up fine.
We have two year old injectors, glow plugs are new and work. starter and batteries are new and it cranks nice. Put in and relocated new PCM. Test the fuel output at purge valve and that seemed fine. Tested fuel pressure and that was within spec's. Changed Fuel filter twice. Checked it cold this morning and there was fuel in fuel filter canister. Just got it started and towed a small backhoe 30 miles and back. It ran fine, maybe a little short on power.
ANY IDEAS !!!
thanks
