This is extremely broad, and vague but I'm getting no spark and have tried several things and can't figure out whats wrong. I'm getting no spark out of my coil. It ran fine about six months ago when it was parked. It is a 1976 280Z 2+2.
If you have determined for certain there is no spark coming out of the coil, you then need to trace back in the circuit to find out why. Is there power on the positive terminal of the coil (primary side)? Also check the negative primary side. If all is well on both sides of the primary, the problem is most likely the coil itself.
