HI,
mfi? Still think fuel pressure is to high, about setup on car if you have the kit,
check fuel pressure system should be 5.65-6.0 bar and differential pressure(lower
chamber pressure) of the fuel distributor say system is 5.8bar, the lower diff presure should be5.5bar. if this is ok, check timing by eye if you cant run engine
look for any air leeks from the air sensor metering unit to the turbo and from it to
the intercooler and to the engine manifold, plug leads are on the correct way round,and the valve timing and sensors are all ok especially the coolant temp sensor for the ecu, and engine compression is good it should be ok get it warmed up and check co% and air sensor plate position and its not sticking,If this checks out maybe ecu signals.
