Thanks Alan ...yes the car has been sitting for the past 6 monts and I have 
never removed the oil pump...the oil pressure is often slow to prime on it's 
own but it always does it in short order...this time I saw no increase 
within the first 5 seconds and chose not to let the engine run any longer in 
case of damage. The other P6B  started and primed quickly but not this 
one..first time it has happened to me in over 30 years so I think the odds 
have caught up to me :)
