Hey everybody, Im just about to get my 1z powered T4 van back on the road but after fitting an AFN cylinder head to the 1z block im experiencing a few problems.
Today, I got the AFN head fitted to the 1z block with the AFN injectors. I got the timing set up nicely and the engine fired very quickly after bleeding the fuel.... but I was getting shed loads of white smoke from the exhaust, which was very strongly diesel smelling. Just for clarity, it wasnt steam as I havent got the coolant system back together yet.
So, i havent got the correct tools for advancing and the retarding the IP so i just fiddled with the pump position to see if i could make the white smoke go away. No matter what I did it didnt get any better..... but then I remembered I had a few issues running on Vegoil last year which may have damaged this IP so I decided to swap the 1z pump for the pump that I got off the AFN engine I took the head off.
Right now, ive got the 1z block, ecu and turbo fitted with the AFN head, injectors and injector pump.... but now I cant get any fuel to come from the tank to the injector pump. There is definitely fuel in the tank, as I just put an extra 20 litres in it, and I can hear the solenoid "click" when I turn the key. Is there a lift pump on it somewhere that I havent seen? The van used to be a 1.9 NA (1x?) which i didnt think had lift pumps but please correct me.
Is there something in the electronics thats preventing it from pumping? All the connections for the AFN pump fitted fine. The 1z ECU has the immobiliser disabled... what else is there?
Please help... id love to get this thing running again
