Hello. Sorry for my English. I had burned my ECU, part number 362067 and a change it with part number 349231. Now my 6G74, V25W, crank and have a spark. But when I put key in on position, do not have injector voltage. Please, I need help. I am not a mechanic, but I want to know how my car works. Please, I need terminal voltage reference of my ECU md349231 and the injector drive md346802. Anyone have it?

Hello,

Here is a guide to help you check the power and grounds for the PCM and the engine wiring diagrams to help you do some testing to find out what the problem is:

Hello. Sorry, but I do not know if the problem is in injector driver or not? My Pagero gdi, 3.5 ltrs, 6G74, from 1997, V25W have a injector driver connector with 26 pins. 7 from ECU to injector driver, 6 i think to control ground injector in injector driver and 1 which I do not know, but are in 91? position of the ECU terminal.
12 to injector driver to injector, 6 are ground and other 6 it should be posetive, but now without any voltage.
Other 6, 3 of them have 12 volt and other 3 are ground, and all have continuity in 2 terminal. And the last pin is empty.
Is it possible which the wire in position 91? Of the ECU control the injector driver transistors?
Sorry for my English.

Pin 91 is for stick shift so do not concern over that. I would check the engine control relay. Here is a guide to help:

They also call the engine relay a PCM relay. Check out the diagrams (below). Please let us know what happens.
