Ecu Not Responding To Diagnostics

.
At worst take it in a van to Clive Wood. If anyone can sort it its him.

 

google him include the word triumph it's easier

 

Or facebook Clive Wood Triumph if that's your thing. You can communicate with him up till late that way

 

Did you have any luck Herbos? I have a similar problem with a T595. Voltage drops from 13.3v to 12.4v as soon as ignition turned on so ecu won't respond. It's all pointing to the fuel pump at the mo. Did Clive help you at all?

 

When you attached an additional car battery (via jumper cables) did you get the same voltage drop? It would help diagnosis to know the answer to this test.

 

Yes. And also with a jump from running car I got a drop from 14.4v to 13.3v with ignition on.
Also can you tell me what the black pump like thing in the middle of the picture is? I have disconnected it but still get a voltage drop so not the problem.
Cheers

 

that black pump is your stepper motor, controls idle, so do not disconnect it.
