Hey guys, we just bought an 1991 accord EX-r (canadian version). The car didnt start the next day. We diagnosed the problem to be a faulty iginter.

First off, how do i know if i have a F22a1 a4 or a6 engine in the car?

Second, there are 2 igniters, 2 mounting holes and 3 mounting holes, how do i know which one i have? I dont have the car with me, its at school, and its closed till the 5th of january.
