What is minimum electrical required to start my car?

I didn't read all, but your problem is you started out trying to sound "in the know", throwing around squishy terms like "engine doesn't get fire", as if that means something. Sounds like "starter doesn't turn engine over" was the initial problem. Also, always describe year, model, engine and such when asking. When you get to verifying spark, have a $5 in-line spark tester from Harbor Freight (or better).
