my crossfire cranks but wont start, also the engine light has been on since

I was having the same problem and googled the symptom "mystery no start" and found a guy in Sierra Vista, Arizona who advised the issue is the Relay Control Module (RCM). He has step by step instructions to locate it and repair yourself (if you are so inclined). I tried but was unable to get to the pins that needed soldering, so I shipped the part to him and he repaired it and I had it back in one week. I have not had any issues since. ps I found him on a Crossfire forum

I soldered the 3 pins a year ago worked fine for about a year now the prob is back so I re-soldered the 3 pins on the RCM also changed the crank case sensor and the cam shaftproblem.still same problem thinking of replacing the RCM Board
