'91 Honda Civic, Distributor Problem

Q: I have periodic problems with the distributor on my ‘91 Honda 1.5 Civic. I use aftermarket distributors but none seem to last more than 6-9 months. I also wonder if the fuel relay switch could work periodically without stopping completely.

A: I have a little difficulty tying the repeated distributor failures with the fuel relay. Honda does use a relay (fuel/main) that if failing or failed will cause the engine not to start. My experience has been that once the relay starts failing the problem becomes very persistent not a 6-9 months apart. Distributor problems- that’s different. Generally distributor failures are mechanical or electrical type failures. The mechanical type failures are often the result of a loose timing belt. The slack in the timing belt allows the camshaft that drives the distributor to jump/snap back and forth. Over time the back and forth motion will loosen screws. The result is a damaged distributor will no clear explanation why. The other killer is a bad electrical connection. The most damaging problem is a poor ground connection. A poor electrical ground will cause the ignition module (ignitor) to eat itself up electrically. Once again this is a "takes time" type failure. If repeated, distributor failures are killing your Honda’s engine you may want to look deeper. It s not the rebuilt part that’s the problem, its just the result of a problem.
