hey all need help asap, just finished fresh rebuild, we had some probs getting it to start, finally got it fired and threw trailing side code, now i have thrown this before and just cleaned the connectors and away it went, but i also lost my tach both factory, and aftermarket and safc as well. really want to take it for a ride someone help quick i am going to continue to diagnose in the meanwhile. thanks in advance

 

okay update, tested for spark, while cranking spark and tach work fine, but as soon as it starts (fires) i loose spark on the trailing coils and tach goes inop. i am going to try to get ahold of a friend locally and borrow a trailing pack but would still appreciate some help in he meanwhile.
