When Moses was a baby, fuel injection was that mysterious fuel system found on the cars of a few technically innovative manufacturers. The carburetor, tried and true, ruled the roost. Those technicians competent to repair fuel injection systems were ranked right up there with magicians, and harder to find.

Unfortunately, the proliferation of injected cars hasn’t necessarily made diagnosis or repair any easier. We don’t just have fuel injection anymore. Now we have engine control systems. They are sophisticated and complex. Those technicians who didn’t get to tinker with injection systems in a simpler time may have a hard time learning everything at once on the newer cars.
