You know the coil is building a charge but are you 100% sure the ICM in the distributor is working? This module runs the whole show - tells the coil to build a spark and sends a pulse signal for the injectors to do their thing. It seems nobody on the internet can agree with what to call any of the related sensors that are accused of creating the error code 15 fault (idle motor position sensor fault). I got TPS, ICM, PCM, CPS, and then side tracked onto IAC's and power transistors. Then I got really stupid posts like - https://www.maxd50scene.com/threads/...ad-distributor
