Mick stout 1uz Posted September 2, 2020 Report Share Posted September 2, 2020 Hi all, I am in the process of wiring a link g3 to a toyota 1uz. The ecu was previously used on a 1uz desert buggy and had a tune installed already. I have now wired it to a different application using a 1uz but I am having fuel issues... So I have installed a fuel pressure gauge on the fuel rail after the stock pressure regulator just to see what is going on. When I switch on the ignition the fuel system primes and I get 28 psi at the gauge, the pressure then drops to 0 psi within a second. After cranking the engine wont fire and pressure guage remains at 0. It will fire on starting spray and when I pull out the spark plugs there is no fuel on the plugs. When I perform the injector test and using a stethoscope you can hear all injectors clicking, however the first bank is quieter than the first bank? Not too sure if this indicates a weaker earth? Furthermore, I don't know the last time the engine ran, so there is a very high potential that it could be blocked injectors aswell. Or it could be a simple click of a button. Thanks in advance for any suggestions or feedback. Quote Link to comment Share on other sites More sharing options...
