Hello all, i was wondering if i could get some advice,
I swapped my old AFN engine with a 1Z engine with the old AFN turbo and put the AFN injectors and pump on the 1Z block. The ECU is also the AFN one but after doing all of that the car wont start. Timing is spot on and i've tried turning the pump, but no luck. Weird thing is that the vcds says that the modulating piston movement sensor is only getting 0.75v instead of the 1.5v that it should get? And the injection valve is 95% open when the ignition is on but when you are cranking it goes to 45%, have also tried swapping crank sensors.

I had something similiar. Changed my 1Z to AHU. Changed the ECU still didn't start... changed the immobilizer block and the engine turned on the first turn.

I dont think it is the immobilizer because the light for it turns off like normal? And i used the old cars ecu aswell?
