Bit of an update..
Remove the petrol cap to ease any tank pressure before removing the pump - had a think about it before starting so I didn’t get a face full of fuel
Tie string to both pipes and the wires in case they drop down. I’d guess it will be a bugger to re find them if they drop down.
I removed the fuel pump to check if the rotor was just blocked / jammed..
Gave it a knock and connected it direct to the battery and... No Joy

.
Scratched my head and tried it reverse polarity and hay presto Bzzzzzzzz

then in forward Bzzzzzzz

.
Put it back in the car and after priming a couple of times, locked up again.
So without removing the pump I reverse polarities it by removing the rear 2 pin connector and putting 12V the wrong way across the pins (with a fuse inline just try each way till you can hear it Buzzz), then reconnected the proper wire and got my car going.
Its now a bit hit and miss, so I think I'll need to remove it and flush the pump fully..
Till then I have the kit to reverse polarise the pump each time it fails.
This is the pump on the assembly which contains level sensor
However the Electric fuel pump can be split from the assy and serviced alone
This bare fuel pump (apparently) also fits "SYTEC REPLACMENT IN TANK FUEL INJECTION PUMP

I was Under the impression that the MK2 Uno with carb (1990 - 1992) has a mechanical fuel pump :S
