warm starting 200tq

[cobram@juno.com]

Before you go shot gunning, you should follow the Bentley and start
eliminating the most likely culprits.  Very detailed instructions on how
to check fuel pressure and delivery, spark etc.  That being said....if
the injectors are OEM or haven't been changed in a decade, change those. 
Another likely culprit is the fuel pump check valve not holding pressure,
procedure for checking is in the Bentley.  Carbon, on the 200 not very
likely, but to remove all doubt run a can of GM top end cleaner through
there, can't hurt.  BTW-use the liquid, not the spray, the spray is no
where near as effective as the liquid.
