    You have pretty much tried every thing on the fuel and electrical. Must be mechanical. Have you checked all the filters for metal? I hope they are all clean,

    Leak down test is good. Have it at the dealership now for a diagnostic test

    Looking back at your original post the problem could be some type of intermittent short or defective component in the electrical system that drains the battery and affects the ignition. Time to start looking at the wiring harness. Do some research on this forum on what defects others have found in the wiring harness and CDI.
