Sniady,
Cant help you with the cold start question.
But I can sypathize with you on wiring. If a PO has done some re-wiring, you are in heaps of trouble, also any car that is over 30 years old probably could use a new wiring harness. Now the real problem, how to get a new harness for a 30 yr old Alfa?
I found this place, and looks like a really nice universla harness. Im thinking of using one of these, once I strip the car down, price seems reasonable. Anyone use these?
