open injector circuit
The code is telling you open injector on cyl 3. That means the PCM expects to see a certain resistance value on that circuit, and instead it sees infinity, or at least a spec way out of range. Check the resistance of that injector against another injector. If they are the same, then the problem is in the wiring somewhere. Trace it back, somewhere you'll find an open wire or some nice green cheese at a connector. Could be a bad PCM, but not likely. Subsequent codes that you are setting are because with that injecotr not squirting, you are not running right.. Fix that open #3, clear all codes, then verify the repair by seeing if other codes return. Mike
