OK thanks TT.
Think I have a better idea now of what I'm looking for.
If there is no spark then it's the fault of the TFI.
And not the ECU, which is where I was looking.
So back to you earlier post.
If I check power and earth to the TFI is ok
and still no spark then its coil end not ECU end
If that is correct then I'll strip out the loom again.
And redo the TFI to coil and dizzy connections.
And ignore the ECU for the moment.
It's half past bedtime for me.
So logging off now.
But will log on again in the morning.
Then I can digest what you said with a clearer head.....
