17- Spark Reference Circuit
18- Cam/Crank Error
34- MAF Sensor Low Voltage
42- Electronic Spark Control Circuit
53- ?????

I sent a PM to Willren and he said it'* probally the Cam or Crank Sensor that'* causing my car from starting. Which one could it be? Should I replace both just in case? also what is code 53? because it isn't on the list.

Is the Electronic Spark Control Circuit the ignition module?

The circuit is vast. It includes the ICM and the crank and cam sensors. That'* a duplicate code if you want to think of it that way.
