Hi guys an girls.

I have this Uno 60 1.1ie
From 1991
Engine code 160 A3.000

One Morning the car would not start it have Been running fine the Day befor
, it gets no fuel
The ignition works ,an if i spray starting fluid in to the monopoint unit
If fires op an runs nicely until i stop spraying fluid in it.

The fuel pump reley is not aktiv gets no signal from ecu
An the singel fuel injector gets no signal from the ecu.

I have check that the fuel pump is ok
An the wirring to it is also ok
The fuel pump relay is ok
The fuse for the fuel pump relay is ok
There is life feed with 12volts to the fuel pump relay
The signal wire from the ecu to the fuel. Pump relay is ok
The ecu get 12v an Earth is ok
The fuel injector gets 12volts
The fuel injector signal wire from the ecu i ok
If i ADD Earth to the injector it opens an Let fuel in if hot wire the pump first
I have tried an other ecu but nothing changes still no signal from
Ecu to fuel pump relay or to the singel injector

I have Been working on the car for som time now an i just Can not
Get my head around what is wrong with it
