A few weeks ago my 99 6 speed truck started intermitently loosing power. I checked fuel pressures and had no less than 9-10 at wot . Checked codes and found 216 code. finaly broke down and installed a new vp44 and the problem is still there. Fuel pressure seems ok still holding no less than 8 &1/2 at wot. I know thats not great but i thought its still enough to run. The power is flat and revs very slow. ????????????? help.
