The vehicle has no fuel or spark, and plugging a Tech2 Scanner tool does not even see it.

 Tech2 tool does see and speak with immobiliser

Is the pinout diagram as shown in pdf file  99501_61A20    The EGR Stepper motor supplement...is this the pinout to use?

 Where should i start ?  guessing check power feed to it?

 Oh, ECL light comes on when cranking and stays on .  motor never fires.

Never had any flash codes

have sent e-mail too.

Just away for the next two days,  back Thursday and then I hope to get upside down in the footwell and see what I can see.

A lot of the information that I had on this ECU was lost in a double hard drive failure a few years ago. I want to do some more mods to my Vit so I'm going back over the code, its not a lot different to the earlier 8V ECUs, the 56B30 and its variants, but the ECU uses updated and more powerful hardware based around the 76C175/MH6211 processor. The software has a few tweaks to handle the immobiliser and the stepper motor EGR and is restructured a little.

The source code is linked below, the TunerPro files are posted in the TunerPro section of the forum.

Source code

EE88 Source Code

The source code was originally disassembled mainly by hand in a word document but I'm slowly reformatting it in MiniIDE to allow it to be recompiled using the TASM assembler, details here:

I have most of the schematics for this ECU and the source code. Ignition and fuelling tables are known.
