Hello Wolfstalker!
what was final resolution on your nonstart? Had similar challenge last Friday and now vehicle sitting!
Had RCM resoldered 1 3/4 ago by an engineer (confident that is not the problem) and car has been perfect since. ...Until now. turned over 3 times, then engine would not start. Dash lights up as should, headlites fine, but car reads "start error". Appreciate your response. Bob D
