Finally I found the problem my Zetec engine.
As always, everything was very simple. After reading a bunch of information about Emerald ECU, having tried various settings ECU, I measured the level of the oscilloscope and the phase of the signal from the crankshaft sensor. Proved that the sensor has been connected with reverse polarity. Just on the sensor did not specify - and signal ground. And in reverse polarity sensor is unstable when the engine is hot. Now engine starts well and is stable at any temperature. So if someone has run into this problem, see the polarity of the crankshaft sensor.
Good luck!
on your return line to your tanks, how is the fuel discharged back into the tank? Do you just have a welded on fitting or do you have a welded in tube which discharges below the level of fuel in the bottom of the tank. You may have fuel aeration?? Just grasping at straws really, reverting to how it was setup on the 164 should solve your problem, just difficult to re configure it like that. Guys method of the complete pump assembly fitted in the tank is as good a solution as any.
