My wife's 760 has not been very happy about starting lately but will eventually after letting it sit for a long time. My suspicion is the fuel check valve and/or fuel pressure regulator, however, the car also (and has since we've owned it):

- surges and sags after starting it
- is harder to start in cold weather
- has a ignition vacuum advance valve with nothing attached to it!

Ack. Anyway, my Neon I can fix no prob but this old dinosaur leaves me stumped (just who designed the layout of that abhorrent V6?) We would appreciate any help.
