I have been knocking out each of these repairs one by one. So far since my trouble began in October I have replaced the battery (under the hood and in my key FOB), re-soldered the RCM, replaced the SKREEM and sent my RCM to Tighed1 for test and repair. I got my RCM back and no change in the current no-start symptom. The best way to describe the current no start is that the engine cranks but there is no spark to fire it all the way up, it just keeps going wha wha wha wha wha wha. I did replace the CKP Sensor about 6 months ago and it seemed to be fine until now. I will admit I purchased the cheapest one I could find so maybe that's the problem. Replace the CKP sensor is the next task. I am wondering if I should just do both the CKP sensor and the CMP sensor at the same time?
