A weird starting issue developed with my Dad's 2000 Grand Marquis when cold.
It won't start when initially cranked. Engine turns over fine, and fuel is up at the fuel rails, but just cranks and cranks.
Pull off the air intake tube at the throttle body and it starts fairly quickly, but if you re install the air tube right away it dies out. Pull the tube off and it starts fine.
After a couple minutes, you can re install the air tube and it's fine, until you put it in drive, the stalls out.
Redoing the process works fine and so long as you wait a few additional minutes, you can put it in drive and drive it like normal.
I had similar issues (dying out once put in drive) on the 86 a few years ago, and cleaning the bijesus out o the idle air control valve worked wonders. Did they have IAC valves in 2000? Any other ideas?
