having read the numerous similar threads on this forum and as a new member I find myself with a very frustrating problem. For background, I have (actually my wife has) a low mile (14K) 2005 srt6 convertible. It has run like a clock since we got it in 2007. This year, getting it out of winter storage, I had to crank it several times before it would start (cold start) on 3 occasions. Once it started it ran perfectly fine. Finally, on the 4th attempt, it would no longer start (but cranks normally). I changed the CAM and Crankshaft position sensors (Bosch OEM new) and no change...it still just cranks. What's next? Help...I dread getting fleeced at a dealer and would love to find a DIY solution. Fuses look good, other electronics are working. Did I miss a step in the process? Disconnect the battery? Fuel pump (although I doubt it given the sporadic nature of the problem with normal operation once started).. any clues would be greatly appreciated.. thank you.
