I changed the crankshaft position sensor, and my car still won't start what should I do?

Question

2004 Kia Optima 2.4L, I changed the crankshaft position sensor, and my car still won't start what should I do?

Answer 1

Sometimes this code can come up even with a bad cam sensor on these. I would check for spark and fuel and see which is missing. If either. It is likely going to require a lab scope to check the patterns and make sure both sensors are working.. You will also have to check the wiring from the sensors to the pcm.
