Angry No spark on trailing plugs

I have no spark on my trailing plugs, I replaced the ignition coil, and ran a test on the ignitor, and it checked out fine, the spark pulgs are all ngk and so are the wires and I believe they are less than a year old. The car will run on the leading plugs, but is very weak. Any ideas on what could be wrong? Its probably something simple that I'm just overlooking. If it hepls at all, the previous owner was driving the car in hard rain, when he said the engine just lost power and died after a mile. Any ideas woud be appreciated.

Try swapping the leading/trailing ignitors at the distributor? See if you get spark on the trailing and not the leading. I take it your tach is dead right?

This happened to me, except it was the leading that died. Horrible performance (about 40HP butt dyno) and worse mileage.

Sure you got your leading/trailing right? No offense, sometimes they get confused.

I'm, pretty sure I have them right, trailing is the top plugs, right? I went out and checked the fuses, one of them was falling halfway out, not even fried, just loose. Pushed it in all the way, checked the plugs, and I have spark on all of them My battery is almost dead, so its on charge now. After its good, I'm going to go try to start it. I can almost gurantee it will run great. Gotta love $500 cars that are this easy to fix

Even better than that is sub 100K motors that are sitting in the junkyards not because they threw a seal, but because of a vacuum leak (hose right above the exhaust manifold gets brittle, and when it does, the car WON'T hold an idle. People then ask mechanics for advice which ends up in an unneeded carb rebuild, then they think it has low compression... )
