I am having a starting problem with my 16v scirocco. I am getting primary power to the ignition coil and can smell fuel. When testing for spark I got a yellowish/orange arc. I also tested for continuity in the ignition switch and all tests seemed to pass except for the test between the 30 & Su switches. Engine stumbled a couple of times during the effort to start but never fully turned over. Since the car was last running, I have also removed the air conditioning compressor, and condensor and don't know if this could be the cause of my problem.
