Baffled by ABZ

[SimonT25]

It has just occurred to me that i havent connected the alternator as yet as i was eliminating things that may be pulling 12volts down.

Is it essential that the Motronic must see 14v on start?

Also as it has an independent fuel supply it is not controlled by the Audi loom fuel relay there is no power to the pin on the ECU!

Again must the Motronic see 12 volts from the fuel relay to maintain engine running?

I will go and amened these things to see if this will make a difference. I would of course appreciate it if anybody on the forum does know this to be fact incase I rectify these conditions and it makes no difference.

Regards and thanks in advance
