Have been rebuilding it from a rev2 na to rev 3 na and now have an error code. Its error 21. I know its not the fuel pump as this is running when the car starts and still seems to be feeding the filter even when the engine cuts out. The car is starting, idling a little rough but nothing more than expected for an engine that had been sat.
It then cuts out. It definitely seems like an electronic cut out, like the ecu is turning the engine off.
