If you had spark before all of this work it is either something you did or you installed a defective part. The first thing to do is a visual inspection making sure that you didn't inadvertantly knock loose a plug or wire. Next remove the coil to distributer wire at the distributer and while someone cranks over the engine see if you can get spark. This will tell you if the problem is in the primary or secondary part of the ignition system. Be careful as there is a lot of voltage here and you can get hurt if not done safely. Let's assume no spark. Check again the wires on the ballast resistors, and coil. If you don't see anything wrong use a test light or meter and see if you are getting any voltage on the coil. Now let's assume no voltage at the coil. Check fuse # 1. Refering to M:18:04 check for voltage at UY and W at the ballast resitors. If you get voltage and the fuse is good then you are left with a bad ECU, or pickup coil in the dist. The most common failure point is either a loose plug to the pickup coil or a bad coil. It is highly unlikely a part failed during a tune-up. The most likely problem is you knocked a wire off somewhere or the plug to the pickup coil.
