We decided to back up and take a fresh look at our Sunshine Yellow 1992 Mazda Miata. Why wasn’t it starting?

Air? Check. The filter isn’t brand new, but it’s not too gross either.

Fuel? We have a new pump—yes, it works—and we replaced the old injectors with a set known to be good.

Spark? All of our wires, plugs and connections look good.

What about that extra box underneath the dash—specifically, the Ungo Box alarm system?

Yes, this car has an aftermarket alarm—one so vintage that it's totally unsupported in today’s day and age. Adding to the dilemma is that we don’t have the required fob. Ruh-roh.

We poked around online and found a few others in the same situation. The easy fix? There doesn’t appear to be one. This system is very invasive as it’s wired to just about every system in the car. Until the box says so, it won’t energize the ignition system.

Right now, we’re looking at bypassing or removing the system. It may take us more than a few minutes to do, however.
