There was a thread several months ago about wiring up a starter relay to fix the common no-start problem - the ignition switch wears and has problems getting enough power to the starter to kick it, especially when the starter is older. Wiring in a starter relay would likely solve the problem without replacing the ignition switch, plus prevent it from happening again in the future.

I'm not saying that replacing the ignition switch isn't an appropriate repair, just that there's more than one way to skin a cat. <img src="/forums/images/graemlins/smile.gif" alt="" />
