Max,
Continued run down on fuel rail is the order of the day. After that timing.
The car cranks healthily but no catch, spark, or sputter. Just the churning of the starter. Check engine light not on. Battery pulled to charge, so codes cleared. None have reappeared. The ground is a good suggestion. I always forget that one crucial piece.
Jason,
Thanks for the feedback. Boots are on tight but do remove easier than others I have seen.
Thanks guys. I will continue the diagnose. I just did not want to overlook this possibility.
