I bought the car with a known broken timing belt. We Replaced all the valves in the head and one bent rod. It started right up, and after the lifters pumped up it runs on 3 cylinders. I immediately thought we pinched the spark plug gap closed with the valve spring compressor so I checked it but it was fine and it has bright blue spark. I can disconnect the spark plug wire while it is running (with insulated pliers of course) and #2 does not effect the engine speed when disconnected. My conclusion is, spark? yes, Compression? yes timing? yes, the other three run perfectly, must be a fuel issue. SO my question is, is there a way to check the fuel injector and see if it is firing? should I swap cylinders and see if the misfire follows the injector? Also there is no error code.
