    Never starts on first try

    I've put an LS2 from a 2006 GTO into a Miata. It runs great, but it never starts on the first attempt. It just cranks and cranks. It always starts right up on the 2nd, or subsequent attempts. It doesn't matter if it's hot or cold, recently started/run or not. Fuel pressure is fine. Injectors/coils have power. We've even tried giving them direct power from the battery. VATS have been tuned out. No OBD codes are being thrown. Yet something is preventing it from initially starting. I feel that it's a computer related issue, like something isn't wired correctly. Any ideas?

    Thanks,
    Jon

    Definitely computer related. Sounds like the VATS was not completely disabled. If it always starts on the second try, let it be. If not, send the ECU to John Spears at Speartech.
