DO not be satified with an eyeball check of solder joints on the RCM, most would recommend looking closely with a magnifier.
Others would say if your comfortable with an iron in your hand, hit those joints with some hot solder.
Best case it solves your issue, worst case you got peace of mind.
Typically no crank but lights = RCM.
Engine hot, then dies, Cranks hot but no start, restarts later after a nap = faulty CPS (Crank Position Sensor).
