My 1st thoughts John, could be proved by filling the tanks full? When replacing the engine, I also revised the fuel config. I now have the Bosch 044 T'd in direct to the tanks (No swirl pot) and the return T'd into the top of both tanks (Poss vapourisation!!)........................Rob, I'll send an email to Emerald and see what they come back re settings. Interestingly, I picked this up from another forum and may have a play today..................He's from Hungary and translates via Google...Hi, guys!
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!
