Hi Genis 149, I see that you have seen does not reach the pump, as is logical for an engine to have gasoline and spark; So if I am not wrong, they carry a relay that feeds the pump and the ignition, called "injection reliable" in the Citroen or PSA "Bitron" or something like that, in other "taquimetric", etc ... In your case you should check if when you give contact and turn it comes to spark to the spark plugs, you have to look at this too, because if you connect the pump direct Pulse "(I don't know if you also checked this) and that of course there is a spark to start ...
I am not able to send it (I don't know if it is my pc or the page?) Search the Internet:" Picasso Gasoline Injection Relion ". Well, apart from what has been said, the crankshaft collector is very important, but it does not appear in the diagnosis you showed, so for now we will not go for it. Check the above, the injector pulse (with test lamp, eg) and the spark plugs. Greetings!!
