What should the fuel injector reading be on a car?
Most injector readings should range between 11 and 24 ohms. Fuel injectors should be tested cold unless otherwise specified, temperature variances will change the readings. If the test shows high resistance or an open circuit the injector needs replacement.

What causes an injector to fail in a car?
Typically, when injectors fail, the solenoids often short internally, causing a drop in resistance. If the specification calls for 3 ohms and an injector measures only 1 ohm; it will pull more current. Too much current flow to an injector; may cause the (PCM) injector driver circuit to shut down.
