Ok guys just got round to the stage of starting up my xud 205 conversion
So it's an xud9 with a Bosch pump, put fuel in the tank primed he system and turned the car over a fuel times with out the heating could to bleed the system then tightened up the fuel lines ready to properly start up!
So the big start up!
Turned the key for it to start up as normal bit noisy and smoky to start as expected with an engine out job, so the engine ran ok for about 10 seconds took a tiny bit of revs then died , we then tried again and either will start run for about 5 seconds get really lumpy and loads of smoke then die.
So I checked the timing just for piece of mind checked the primer was facing the right way haha and checked all air intakes were clear, then bleed the system again and the same thing keeps happening, so tonight me and the old man tried this.
We used a little bottle for a fuel tank onto the primer then onto the pump and we were going to collect the spare fuel out the return into a valve, we did this to eliminate the other fuel line and then this will tell us if the problem is in the fuel systems (air leak) or in the pump.
Except the funny thing is although it's taking fuel In as normal there is no fuel coming out the fuel return line out the pump, and there is loads of smoke, again the engine will start good and run for a short time the get lumpy and cut out, is it getting too much fuel and why? And why isn't there any fuel out the return line? Is there perhaps something with in the pump that is stuck? Any help would be good thanks
