My sons got a 2006 600 SDI renegade. The history is we bought needing a front nun 1 owner in perfect condition he hit a culvert. This past summer we replaced the nun and drained the fuel out if the tank, put in new and it started and ran like a Swiss watch. I ran it around the yard a couple times and it ran perfect. It sat in my garage 3 weeks went to move it and it starts up runs 2-3 seconds and dies. It will do this every or every other pull. I've replaced the battery with new, put in new plugs, switched around the 3 relays, even went as far as removing the fuel rail and injectors energizing them with 12 volts and spraying injector cleaner through them. As far as I can tell it's getting fuel for the start charge but that's it. Only enough for the 2-3 second run then dies. When it first ran the engine light was always on there are 2 beeps then 3 quick beeps each time you go to start it. Any input would be appreciated. Thanks
