I had the same problem with my VX. Once in a while it would have to crank many times with partial throttle before it would start. Once started it ran like normal, no problems. It starterd to happen more frequently, especially after it was off for just a short period of time . I finally took it in to the dealer and they performed a fuel pressure test. They replaced the fuel pressure regulator and also the intake manifold gaskets under warrantee....... It seems fine now!
