It is not getting fuel, even after installing tested in-tank pump and used main pump. Fuel simply not coming out of tank

We set up an independent fuel source by hooking straight into the main pump intake - fuel not getting up to engine

Interestingly, the '561' ECU is giving more animated fuel pump relay and main pump responses ie, clicking/whirring every ignition 'on'. The '951' ECU needed 5 minute intervals before pump whirr (prime)

Jump on bicycle now 20km over there collect fuel pump relay and resolder

Day 7!!!

If the original ECU was a '561, it's a B230F, that means it's the LH2.4 with a Lambda sensor and a CAT. There is also a known problem with the '561 and '951 ECUs for the fuel pump :

Check fuses 1, 11 and 13 while you're over there on your treader.
