Hi, I'm new to this website and just looking for some answers for my OBD0 to OBD1 conversion I just did. Before I converted the car over to OBD1, the car ran perfect. But now, since I converted it over, I am getting ecu code 9, which is for the crank position sensor. I bought the distributor from King Distributor brand new. I have the directions to convert OBD0 to OBD1 and I've tried different wiring configurations and I still get the same code 9. I also checked the car with a timing light and I was just wondering what mark lines up with the timing belt cover. There is a 3 slit mark and a single slit mark on the crank pulley. The only one that lines up with the crank pulley is the three slit mark. I cannot get the single slit mark to line up which I believe is the right mark. Do you think that may be the reason my engine light is coming on? Or do you think there is another reason behind it? Any suggestions would be helpful. Thank you.
