Hey everyone, just joined the boards. Bought my first RX7 last week, a 86 N/A 5spd. Seller said it had a bad fuel pump, but the fuel pump is fine, found out it isn't getting spark. The two black booted coils (bottom plugs) up front spark once(when you first start cranking), but then stops sparking. The two blue booted coils (top plugs) farther back by the bulk head don't spark at all. Sorry I don't know the names for the two sets, is it leading and trailing or something like that? I'm new to the rotary world, learning as I go along on this. Tried searching for a similiar problem, but couldn't find anything, thought maby some of you have run across a problem like this before. Any insight is greatly appreciated!
